was to try to make progress on the motion system, based around a set of motors I ordered the previous week. I could have tried to individually source them, but the all-in-one kit I found was too good to resist.</p> <p>While I waited for those to arrive, I started to print off the supporting pieces. Most of them take the form of an upper and a lower part which is joined together using bolts. This design makes for easier printing of each individual part, as a significant flat spot is then available to adhere the part to the printer bed. A great deal of care and thought went into the Voron 0.1's design here.</p> <p>I knew buying the motors as a set was a bit of a risk, as it could mean substandard parts, but I felt the risk was worth it. Then they did arrive they all seemed to be decent quality. We'll see when I power them on. With all the parts on hand -- or so I thought -- I sat down with the intention to assemble them all. Then I discovered the bolts I did have....were 5mm too short. I put in an order for a replacement and decided to build something else instead.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3552

At the time, I thought for sure I didn't have any plexiglass remaining to make the plate out of. Furthermore, I assumed the tight tolerances required by the machine would necessitate some very careful cutting and drilling.</p> <p>I spent a night or two researching what I would need to do to bring my mostly-complete Dremel CNC machine online to cut the plate, but ran into issues simply finding something to open the CAD files.</p> <p>Then I found a piece of plexiglass on the floor of my basement. Using the same techniques I used for building the <a href="https://deninet.com/TCHeRI">TCHeRI server rack</a>, I cut the plexi down to size using a modeler's saw and a sawing guide. While the fit wasn't perfect, it was more than good enough to act as the printer's deckplate. As expected, I needed to partially disassemble the printer to get it mounted, but that wasn't nearly that difficult.</p></div> </div> </div> <div class="field__item"> <div class="paragraph

the motion system, I decided to work on the printer's lid. The designers call this the "tophat" and it's one of the features of the Voron 0.1 I most liked aesthetically.</p> <p>It also had some of the longest, largest prints of the entire build. The lid is made of four tri-wing pieces with a hole at each end in which to point a heat-set threaded insert. I had previously bought some heat-set inserts and soldering iron tips for them for a small project I never quite finished. Still, the practice was essential; the soldering iron was already primed with temperature settings I found worked very well for the inserts.</p> <p>Once the inserts were installed, M3 bolts and smaller printed brackets held the four tri-wings together to make the tophat. Each corner of the hat also had a small bracket to hold plexiglass panels in place. While I haven't checked for sure, I might have enough plexy on hand to at least finish the sides of the tophat.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3556 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>While I didn't get much built this weekend, I did have some success with acquiring and printing parts. The missing bolts may have been disheartening, but that's to be expected when self-sourcing everything for a machine such as this. Building the tophat and completing the frame definitely makes the printer feel much more real, although it's still yet an empty frame.</p> <p>Maybe next weekend I'll have more luck.</p></div> </div> </div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-hidden field__item"><a href="/topic/3d-printing" hreflang="en">3D Printing</a></div> <div class="field field--name-field-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/tag/diy" hreflang="en">DIY</a></div> <div class="field__item"><a href="/tag/diy" hreflang="en">DIY</a></div> <div class="field__item"><a href="/tag/3d-printing" hreflang="en">3D printing</a></div> <div class="field__item"><a href="/tag/voron-01" hreflang="en">Voron 0.1</a></div> <div class="field__item"><a href="/tag/build-logs" hreflang="en">build logs</a></div> </div> Sun, 07 Aug 2022 19:42:53 +0000 socketwench 1707 at https://deninet.com Voron 0.1 3D Printer Build #1: The frame https://deninet.com/blog/2022/07/31/voron-01-3d-printer-build-1-frame <span class="field field--name-title field--type-string field--label-hidden">Voron 0.1 3D Printer Build #1: The frame</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><a title="View user profile." href="/user/socketwench" lang="" about="/user/socketwench" typeof="schema:Person" property="schema:name" datatype="" class="username">socketwench</a></span> <span class="field field--name-created field--type-created field--label-hidden">Sun, 07/31/2022 - 14:31</span> <div class="field field--name-field-add-sections field--type-entity-reference-revisions field--label-hidden field__items"> <div class="field__item"> <div class="paragraph paragraph--id--3538 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>While I've been very happy with my now heavily modified Ender 3 Pro, it does continue to have a few issues that are so fundamental that no amount of modding can correct them.</p> <ul> <li>The printer is open frame, requiring a large enclosure to house it.</li> <li>The "bed-slinger" design requires even more shelf space to store the printer in operation, making it hard to keep in my office.</li> <li>Due the the moving bed, the top speed of the printer is limited.</li> </ul> <p>And the thing is, I really, <em>really</em> want to print faster and with higher quality. Fortunately, there is an alternative 3D printer design which supports this -- <a href="https://corexy.com/"><em>core-xy</em></a>. In a core-xy printer, the print bed is either fully stationary, or only moves up and down in the Z axis. Instead, the print head is capable of moving across the entire build plate by itself. While it's possible to make a 3D printer meet this definition without being core-xy, many of the fastest printers are. In a core-xy printer, the print head is connected to two separate drives via belts. When one belt spools up, the other has to let out. This allows the motors to also be mounted to the printer frame, reducing overall mass needed to move when the print head travels.</p> <p>While there are several different brands of core-xy printer out there, one struck my interest immediately: <a href="https://vorondesign.com">Voron</a>. Voron isn't a brand, or even really a company, it's a collective which designs some of the best core-xy printers around using open source designs and readily available components. While it was tempting to build a big 2.4, the diminutive <a href="https://vorondesign.com/voron0.1">Voron 0.1</a> (often called "The Voron Zero") was immediately appealing to me. The printer is enclosed and very, very small; I would easily be able to store it in my office without issue. It's small print area of 100mm isn't a huge drawback for me as I rarely do large prints. I prefer smaller prints which can be assembled together. And of course, it's fast.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3539 paragraph--type--image-gallery paragraph--view-mode--default

different in one other respect. You <em>can't</em> buy from them. They have no store, offer no built machines, not even kits. Other companies have stepped in providing pre-made Voron kits, but the current chip shortage has left them all, for me, sold out. So instead, I'm building this by self-sourcing each, and every part.</p> <p>Unlike every other machine I've built, the Voron 0.1 uses linear rails to allow for motion on all three axes. These are precision, machined parts with a sliding carriage. The first step in the build is to assemble four rails, two for the Z axis, and two for the Y axis. The X axis comes much later. The <a href="https://github.com/VoronDesign/Voron-0/raw/Voron0.1/Manuals/Assembly_Manual_0.1.pdf">Voron 0.1 assembly manual</a> provides clear directions on how and where to mount the linear rails.</p> <p>This is also where I ran head-first into another aspect of this project. It's not simply that the printer is tiny, all the parts are tiny too! The linear rails required M2 hardware and special, 15mm square aluminum profiles. After an inexpensive initial test order of these profiles confirmed they were the right size and kind, I ordered more and all the parts needed to make the frame. Taking a lesson from the build of my CNC machine and the Laser machine, I decided to order all the parts pre-cut and tapped to size.With that done, mounting the rails was a matter of inserting M2 nuts into a printed carrier, and sliding that carefully into the extrusion. Printed centering guides and a caliper got me through this first, daunting step.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3541

paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>With the rails mounted to the profiles, the next step was to create the rear assembly. This combines two vertical rails with a square of plain aluminum profiles as support. The Voron 0.1 uses an interesting construction method that I haven't seen before with aluminum profiles. Most profiles look like four arrows pointing away from each other at right angles from a central point. It looks a bit like an X with an arrow tip on each end. Instead of conventional "V-groove" profiles, however, the 0.1 uses a special kind of 15mm square profile. The interior channel isn't so much a V as it is an lower-case t. This allows for M3 nuts to be simply inserted into the end and be perpendicular to the face of the profile.</p> <p>But there's one more trick up it's sleeve on which the Voron relies heavily. Using button-head bolts, you can slide them into the t channel head-down. To access them, a through-hole is drilled in the middle of the profile so that an hex wrench can be passed through and tighten the bolt. It's an ingenious method, and saves a lot of otherwise bulky gusset plates and re-enforcing brackets.</p> <p>To make the access holes:</p> <ol> <li>I used a caliper to mark the distance in the channel to drill.</li> <li>A nail-set was used to mar the profile channel at the location to drill.</li> <li>Using a right-angle drilling guide and the largest bit that would fit in the channel, I drilled on through.</li> </ol> <p>This process seemed harder for the first one, but very straightforward for the rest. As a bonus, if you miss the place to drill, widen the hole some more. The dimensions aren't critical.</p> <p>The next thing to build was what I'll call the rear assembly. It has two profiles with linear rails for the Z-axis, and a square of profiles as a frame. To keep this flat while assembling, I used a woodworking trick of a large piece of plate glass.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3543 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="the-bed-assembly"><h2><a href="#the-bed-assembly">The bed assembly</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The bed assembly was the goal for my weekend. I wanted to put together the small three piece arrangement of profiles and their three printed parts and mount them to the rear assembly.</p> <p>I quickly found that I was missing key hardware for this. Unlike the button head bolts I've used so far on this build, the bed assembly mounted to the linear rails using cap head bolts. While I had plenty of M3 bolts in that form, I had no M2 versions. Acknowledging I'd have to disassemble this later anyways, I used the button head bolts and mounted it on the rear assembly anyways.</p> <p>The result, while simple, left me giddy.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3544 paragraph--type--video paragraph--view-mode--default"> <div class="field field--name-media-video field--type-entity-reference field--label-hidden field__item"> <article class="media media--type-video media--view-mode-default"> <div class="field field--name-field-media-video-file field--type-file field--label-visually_hidden"> <div class="field__label visually-hidden">Video file</div> <div class="field__item"> <video controls="controls" muted="muted" width="640" height="480"> <source src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2022-07/PXL_20220730_224425889.mp4" type="video/mp4" /> </video> </div> </div> </article> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3545 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="the-rest-of-the-frame-kinda"><h2><a href="#the-rest-of-the-frame-kinda">The rest of the frame, kinda</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>I couldn't resist wanting to build the rest of the frame of the printer despite not having all the final hardware available.

For many, they may simply put a half-used spool on a shelf or on a rack where it can be pulled down easily. While this does work, it runs the risk of degrading print quality over time.</p> <p>Most 3D printer filaments are <em>hydrophilic</em>. That is, they absorb moisture from the air over time. For standard PLA, this isn't much of an issue as the filament will generally give good results even if left in the open air. Other filaments, such as ABS or PETG, a much more hydrophilic.</p> <p>Why is this a problem? When the "wet" filament encounters the hotend in printing, the water will instantly boil, resulting in a small snap of expanding water vapor. Since this happens in the plastic, a little bubble or "pimple" develops on the resulting print. Furthermore, wet filament has a tendency for <em>stringing</em>, or leaving gossamer threads of plastic between non-printing moments when the hotend moves to another location for further printing. Keeping filament dry helps to reduce the likelihood of both of these issues.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3529 paragraph--type--image-gallery

keep filament spools dry, but most involve isolating them from free air, and using a desiccant to keep what air surrounds the spool as low moisture as possible.</p> <p>My very, very first filament storage container (version 0) was simply a five gallon bucket with silica gel at the bottom. I could fit four to five spools easily and the cost was very low. If you collect desiccant packs from foodstuffs, medications, or technology packaging you may not even need to buy the desiccant either. It worked, but it wasn't all that convenient and there wasn't a good way to know how dry the filament really was inside the bucket.</p> <p>The second version improved on things significantly. Instead of a single, huge bucket, each spool was now in its own individual storage box. These storage boxes are modified "21 cup" cereal storage containers commonly found in the US. They're wide and tall enough to store one spool easily. I was reluctant to modify these heavily, so I settled on the following:</p> <ul> <li>A small outlet valve would be mounted to the front.</li> <li>A printed "jar" of desiccant was stored in the empty spool center.</li> <li>A roller using bearings would allow the spool to move freely.</li> <li>Any further desiccant could be dumped on the bottom of the container.</li> </ul> <p>The jars also had a special feature. While one side was merely a screw-on lid, the other side had a spot to attach a <em>hygrometer</em>. These meters are also commonly found online, and display both the temperature and the humidity near to the sensor. Since the jar merely sat in the empty center of the spool, no further modification was needed to the 21 cup boxes.</p> <p>A final improvement to the storage solution was to buy a filament dryer. The Sunlu dryer I bought was on sale, and generally considered good enough for use. It also meant not buying a food dehydrator and risking plastic contamination from mistaken cross-use. I modified the dryer nearly as soon as it arrived to add a PTFE fitting as an outlet port, and a small stop on the back to prevent the lid from falling behind the dryer when opened.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3530 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="the-problems"><h2><a href="#the-problems">The problems</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The dryer, while basic, had surprising results. It completely revitalized some ABS that had been left out in the open air for months, making it readily usable again. Storing a similar roll in desiccant after being exposed to open air for weeks didn't result in improvement. The key? Heat. The filament dryer heated the roll, allowing stored moisture to escape.</p> <p>While the dryer was a definite improvement, I quickly found issues with the 21 cup boxes:</p> <ul> <li>The outlet port was leaky and allowed more moisture into the container over time.</li> <li>When removing a spool, the desiccant jar would fall out with a clatter, or worse, break open sending silica gel everywhere.</li> <li>You couldn't read the humidity from the front of the box, only the side.</li> <li>The rollers only had a narrow rolling surface; many spool sizes wouldn't fit at all.</li> </ul> <p>The biggest problem, however, was the desiccant jars. Not only did they fall out annoyingly, but they were far too small to keep the filament dry. I ended up pouring more desiccant at the bottom of each box, but this created further hazards. If the box was dropped, gel would go everywhere. Worse, there was no easy way to collect the desiccant and "recharge" it in a microwave or an oven. It was a messy process, and resulted in exposure to silica gel dust, which is a health hazard.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3531

This would eliminate the need to ever remove the gel from the boxes and improve use and safety. You can actually buy silica gel in such metal boxes already, but I already had a quantity of loose gel, and I wanted to make use of that instead. I thought about printing boxes, but the print times weren't favorable no matter what I tried, and many couldn't withstand a trip through an oven for an intense recharge.</p> <p>The solution I came up with was to buy several metal boxes, often used for breath mints. Since they're metal, they wouldn't melt in a normal house oven, and would be perfectly fine inside the filament dryer. To make sure air could come into contact with the gel, I cut a window in each box -- you can buy them with the windows if you prefer -- using a <em>nibbler tool</em>. Once a port was cut in the bottom of each box, I similarly cut a piece of metal mesh to fit using tin snips, and glued them together using JB Weld.</p> <p>Two of these desiccant boxes can fit on the bottom of a 21 cup container with ease. Three if one is propped up vertically. Even better, three could be put in the filament dryer at a time to recharge the gel. Kapton tape was used to keep each box closed.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3533 paragraph--type--image-gallery paragraph--view-mode--default

After some searching, I found <a href="https://www.thingiverse.com/thing:3988583">this design on Thingiverse </a>which would solve both issues. Instead of the spool resting directly on the bearings, two large rollers were printed instead allowing for multiple spool widths to be compatible. The base or "shoe" of the roller also was perfectly sized to prevent back-to-front motion of the roller in the box.</p> <p>However, the existing design created a new problem: it wasn't compatible with my desiccant boxes. Small raised bumps on the underside of the shoe allowed for nuts or threaded inserts, but made the roller rest unevenly on the desiccant. To solve this, <a href="https://www.thingiverse.com/thing:5425208">I remixed the shoe design</a> to be thicker and completely flat. The added thickness allowed for M3 nuts to be easily embedded into the plastic leaving a flush bottom.</p> <p>Since both the old and new rollers used the same number and size of bearings, I was able to recycle my existing ones with no additional cost.

paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The final, biggest issue was fixing the output port of the box. While I really liked the simplicity of the ones I had printed for the first version, they where very leaky, and allowed outside air to enter the box over time. I thought about designing a replacement cap for the ports, but in the end, the fundamental design of the port was flawed.</p> <p>Again I found <a href="https://www.thingiverse.com/thing:3951296">the solution on Thingiverse as this amazing design</a>. While larger, this port uses rubber O-rings to create an air tight seal. Furthermore, the port's center is a rotatable ball, allowing for filament to exit at a broader range of angles than the existing port. I completely loved this design, but there was one single problem.</p> <p>The original ball has small fins inside to hold a piece of PTFE tubing. The PTFE allows for less friction on the filament as it leaves the box. Try as I might, however, those fins just wouldn't print on my Ender 3 Pro. As you might guess, <a href="https://www.thingiverse.com/thing:5423644">I remixed the design</a> with much more aggressive teeth which easily grabbed the PTFE I had on hand.</p> <p>To ensure a better seal, I used 30 minute clear silicone sealer when mounting the port on the box. It was....intimidating cutting the much larger hole necessary to mount the port on the boxes, but after the first two it was a non-issue. Combined with the O-rings around the ball in and in the cap created an excellent air-tight seal.</p> <p>The remaining problem was hygrometer. Without the jar, it needed a new  place to live on the box. As expected, <a href="https://www.thingiverse.com/thing:4070756">Thingiverse already had the solution</a>. The only confusing moment was realizing that the hygrometer would never go through the box, only the bolt holes do. I added silicone sealer around those as a precaution.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3537 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="summary"><h2><a href="#summary">Summary</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The new filament storage boxes are a huge upgrade from my previous attempt. The seal better, roll better, and I can even check on their status without opening them. Enclosing the desiccant in their own mini boxes results in better ease and much improved safety. Now the process for recharging the gel and drying a spool of filament is the same -- put them in the dryer.</p> <p>Of course, now I have a new problem.</p> <p>I would love it if I could use the new filament storage as intended. When printing, the spool never leaves the box, only goes through the port and into the printer. The problem is that my printer set-up is rather clumsy. The rudimentary shelving unit on which the printer's enclosure rests sits chest-high, with no room at the top to put the boxes. Nor is there room <em>in</em> the enclosure for the boxes. Instead, I remove the spool and put it on the holder on the printer itself. That, unfortunately, will require an even more complicated project to correct...</p></div> </div> </div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-hidden field__item"><a href="/topic/3d-printing" hreflang="en">3D Printing</a></div> <div class="field field--name-field-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/tag/3d-printing" hreflang="en">3D printing</a></div> <div class="field__item"><a href="/tag/diy" hreflang="en">DIY</a></div> </div> Sun, 24 Jul 2022 15:51:23 +0000 socketwench 1705 at https://deninet.com A sign for the Garden https://deninet.com/creation/2022/07/04/sign-garden <span class="field field--name-title field--type-string field--label-hidden">A sign for the Garden</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><a title="View user profile." href="/user/socketwench" lang="" about="/user/socketwench" typeof="schema:Person" property="schema:name" datatype="" class="username">socketwench</a></span> <span class="field field--name-created field--type-created field--label-hidden">Mon, 07/04/2022 - 12:56</span> <div class="field field--name-field-add-sections field--type-entity-reference-revisions field--label-hidden field__items"> <div class="field__item"> <div class="paragraph paragraph--id--3521 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>A front-yard garden often results in a lot of passers by asking questions or compliments.

QR code generators out there which you can use for free. Many require no signup for the most basic of features -- mostly just generating the graphic containing the QR code. Many offer additional features like frames, text, or logos given a payment or a signup.</p> <p>Fortunately, I didn't need either. All I needed was something that could generate the QR code as an SVG graphic file. The process worked like this:</p> <ol> <li>Generate a basic QR code for the URL with no frame, text or logo.</li> <li>Export the QR code as SVG.</li> <li>Import the SVG into the open source editor Inkscape.</li> <li>Add a background shape and text.</li> <li>Export the edited graphic as a high resolution PNG.</li> </ol> <p>That got me an image which is black and quite. The text and QR code being black, and the background shape of the sign in white. Being a PNG, there's actually a third color: transparent. This allows the corners of the side to have a gentle curve.</p> <p>Once I had the PNG, all I had to do was import it into my preferred 3D printing slicer, Cura. Cura has a feature known as lithophane, which takes a grayscale image and converts it into a height-map for 3D printing. Typically, white is the lowest height, and black the tallest, with levels of gray in between. Transparent pixels in the image aren't printed.</p> <p>When importing the image, you configure Cura the height of the base (white), and the total height of the print (black). I configured the base for 2.5mm and the total height 5mm. After that, I had a very nice sliced model.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3524 paragraph--type--image-gallery paragraph--view-mode--default

have an inexpensive 3D printer which can only print one color at a time. I could have faked a multi-color print by changing the filament mid-print, but I had no white filament on hand anyways. What I did have was some Golden Open Acrylic paint.</p> <p>I've used Acrylic paint on 3D models before. While the Golden Open type takes forever to dry it does tend to stick to the comparatively rough 3D printed surface well. So, with a brush and a careful hand, I hand panted in the QR code and text. Each coat only took about 20 minutes to do, but I had to be careful not to mar the base with white paint. Doing so might create errors which means QR code readers couldn't interpret the image.</p> <p>With this done, I needed a way to mount the sign outside. The first was simple. We have a number of purple garden poles which we use to support tall and climbing plants in the garden. Using a hot knife, I created two pairs of slots in the base of the sign through which I could slip a zip tie. Two zip ties and one pole, instant garden sign.</p> <p>A second, more difficult problem was making the sign -- and more importantly, the paint -- durable in a Minnesota summer. While the print itself would likely survive, the paint may degrade quickly without further protection. For this, I got some clear spray paint which was designed for plastics from a local hardware store. After applying multiple coats, the sign was as durable as it was going to get.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3526 paragraph--type--text-with-image paragraph--view-mode--text-image-50 paragraph--type--text-with-image--view-mode--text-image-50 paragraph--type--text-with-image--order--"> <h2> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="but-does-it-work"><h2><a href="#but-does-it-work">But does it work?</a></h2></div> </h2> <div class="paragraph-text-with-image--body"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Absolutely.

While I could have simply printed the human-readable URL, I liked the idea of adding a QR code for quick and accurate scanning as people walked by our house.</p> <p>Hopefully I'll expand the plants page further throughout the season.</p></div> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2022/07/04/Screenshot_20220625-180247.png"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/07/04/Screenshot_20220625-180247.png?itok=apkzphOY 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/07/04/Screenshot_20220625-180247.png?itok=yrk2r9QH 2x" media="all and (min-width: 1200px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/07/04/Screenshot_20220625-180247.png?itok=ar_0m49m 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/07/04/Screenshot_20220625-180247.png?itok=yrk2r9QH 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/png"/> <source srcset="/s3/files/styles/width_470/public/2022/07/04/Screenshot_20220625-180247.png?itok=auFH3SbM 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2022/07/04/Screenshot_20220625-180247.png?itok=6XGROmrS 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/07/04/Screenshot_20220625-180247.png?itok=umkaToSh 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/07/04/Screenshot_20220625-180247.png?itok=apkzphOY 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/07/04/Screenshot_20220625-180247.png?itok=bPHoREhx 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/07/04/Screenshot_20220625-180247.png?itok=ar_0m49m 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/07/04/Screenshot_20220625-180247.png?itok=bPHoREhx 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/07/04/Screenshot_20220625-180247.png?itok=umkaToSh 2x" media="all and (max-width: 319px)" type="image/png"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/07/04/Screenshot_20220625-180247.png?itok=bPHoREhx" alt="A screenshot of the photo app on Android showing the QR code being read accurately" typeof="foaf:Image" /> </picture> </a> </div> </div> </div> </div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-hidden field__item"><a href="/topic/3d-printing" hreflang="en">3D Printing</a></div> <div class="field field--name-field-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/tag/diy" hreflang="en">DIY</a></div> <div class="field__item"><a href="/tag/3d-printing" hreflang="en">3D printing</a></div> <div class="field__item"><a href="/tag/plants" hreflang="en">plants</a></div> </div> Mon, 04 Jul 2022 17:56:29 +0000 socketwench 1704 at https://deninet.com Blinkenlights for TCHeRI https://deninet.com/creation/2022/03/27/blinkenlights-tcheri <span class="field field--name-title field--type-string field--label-hidden">Blinkenlights for TCHeRI</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><a title="View user profile." href="/user/socketwench" lang="" about="/user/socketwench" typeof="schema:Person" property="schema:name" datatype="" class="username">socketwench</a></span> <span class="field field--name-created field--type-created field--label-hidden">Sun, 03/27/2022 - 11:00</span> <div class="field field--name-field-add-sections field--type-entity-reference-revisions field--label-hidden field__items"> <div class="field__item"> <div class="paragraph paragraph--id--3503 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>One of the design motives for <a href="https://deninet.com/creation/2022/01/30/components-and-rack-pi-cluster">TCHeRI (formerly "The Pi Cluster")</a>, was to show off the electronics.

It's why I built the case out of aluminum extrusions and used plexiglass for the side panels.</p> <p>One key item I had yet to add to the case was a logo. While TCHeRI itself now has a logo, my original plan was to use the deninet "brick" logo instead. I actually have two of them already 3D printed; a larger one almost 120mm wide, and a much smaller one. My first thought was to use the large one and split it between the doors, but as the case came together it seemed to simply overwhelm everything else. After a poll on social media, I was convinced to use the smaller, more understated logo.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3504

field--type-text-long field--label-hidden field__item"><p>Kinda.</p> <p>One idea I've had repeatedly is to light up the brick logo so that the banding and "shadow" glow, while leaving the silver parts opaque. The problem was the two logos I already had printed came in two parts. The silver part and red part (the banding and shadow) where printed out of different materials. While the shadow was translucent, the banding clipped over the silver part in the existing prints, meaning lighting it from underneath would be muted at best.</p> <p>Fortunately, I had three things on hand: The STLs for the logo pieces, some silver spray paint, and some translucent red ABS 3D printing filament. In blender, I combined the silver and red pieces into a single model. Then, I printed the entire thing in red ABS. This would allow better transmission of light from the banding, at the cost of needing to mask and paint the model.</p> <p>After filing and sanding the faces of the print as smooth as I had patience for, I masked off everywhere I wanted the original plastic to show through. On a cold, snowy Sunday, I applied layer after layer of silver paint to the part, letting it dry in a bathroom with a window fan venting the fumes outside. Ideally, I'd have just left the part outdoors, but the cold temperatures wouldn't allow this to work, and I didn't want to wait until spring.</p> <p>After letting it dry for 24 hours, I removed the masking tape and the result was nearly perfect. There's a small blemish on one of the faces where the printer underextruded which the paint did not fill in. In the future, I may try to fill that with epoxy filling compound instead. Even so, the result was more than acceptable. As a bonus, the paint was a proper metallic silver, rather than a dullish silver you get from most silver filaments.</p></div> </div> </div> <div class="field__item"> <div class="paragraph

the project was to make the thing glow. I had originally though of using a neopixel ring I had on-hand, or some multi-color two wire LEDs I used in the 3D printed Pumpkins project. Both of these had separate problems. The ring was a lot brighter, but it was physically bigger than the logo itself. Given the place on the cluster's case, I didn't want to make the logo bigger to accommodate the ring. The LEDs would have worked, but they couldn't be synchronized and required 3.3V instead of the standard USB 5V, complicating installation.</p> <p>Either way, I really wanted a microcontroller to control the lights for future tinkering. One micro I had on hand was a Arduino Micro, a now discontinued smaller, breadboard friendly version of the Arduino. It was just small enough to fit under the logo, and I found <a href="https://www.thingiverse.com/thing:4163493">a nice case on Thingiverse</a> I could modify into the outline of my logo. After some more modeling in Blender, I was able to do just that. The pins of the micro actually face toward the logo, with a small chamber in which to mount whatever lights I wanted under the logo. Two through bolts secured the back case to the logo. Instead of bolt holes, I heated an M3 nut at the end of a long bolt and then pressed it into the underside of the logo, matching the bolt holes in the rear case. Repeating the process a second time resulted in a logo with to embedded nuts.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3508 paragraph--type--text-with-image paragraph--view-mode--text-image-50 paragraph--type--text-with-image--view-mode--text-image-50 paragraph--type--text-with-image--order--"> <h2></h2> <div class="paragraph-text-with-image--body"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>But, I still needed to solve that light problem...</p> <p>I have a roll of Dotstar LEDs I bought years ago for a project I never really got around to doing. When I looked more closely at the roll, however, it became obvious I couldn't really use it. The roll wasn't a normal LED strip, but a low density, weather-proof strip. I had intended to use this to wire some windows in my house with a lit up display, so the low density and weather proofing made sense. The weather proofing wasn't too hard to remove as it was just a silicone sleeve around the strip. The real problem was the low density. Each LED was further apart than the logo was wide.</p> <p>I was about to put the project aside and order some neopixels when I found an old LED strip in my junk drawer. This was from the first keyboard I built myself. I did try to install the LED strip then, but it never quite worked in the keyboard, so I removed it and set the strip aside. <em>Could I use this?</em> I thought.</p></div> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2022/03/27/PXL_20220312_231623632.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/03/27/PXL_20220312_231623632.jpg?itok=8SKuDyp3 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/03/27/PXL_20220312_231623632.jpg?itok=Nxor1oQz 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/03/27/PXL_20220312_231623632.jpg?itok=lvs23-zq 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/03/27/PXL_20220312_231623632.jpg?itok=Nxor1oQz 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="/s3/files/styles/width_470/public/2022/03/27/PXL_20220312_231623632.jpg?itok=J8O46eoH 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2022/03/27/PXL_20220312_231623632.jpg?itok=NIIb2Hsg 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/03/27/PXL_20220312_231623632.jpg?itok=-4T6sQbI 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/03/27/PXL_20220312_231623632.jpg?itok=8SKuDyp3 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/03/27/PXL_20220312_231623632.jpg?itok=z_yAiRKq 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/03/27/PXL_20220312_231623632.jpg?itok=lvs23-zq 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/03/27/PXL_20220312_231623632.jpg?itok=z_yAiRKq 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/03/27/PXL_20220312_231623632.jpg?itok=-4T6sQbI 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/03/27/PXL_20220312_231623632.jpg?itok=z_yAiRKq" alt="A small string of LED lights soldered together by wires" typeof="foaf:Image" /> </picture> </a> </div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3509 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Unlike the Dotstars and Neopixels, the no-name strip from the keyboard wasn't four wire, but <em>three</em> wire. After some searching online, I found the pinout and necessary libraries to run the strip. The only problem was the strip was still longer than the entire logo. I would need to cut it in two. Worse, some of the connectors on the strip itself had failed or broken from my earlier, ham-fisted attempts to get it working in the keyboard.</p> <p>This is where the Pinecil came to save me. It's smaller size and narrower tip compared to my Hakko soldering station allowed me to carefully resolder the broken connections on the LEDs themselves. This allowed me to not only repair the strip, but cut it in two and use all six LEDs. The LED strip is connected to the micro using dupont connectors which attach to the micro's pins. I wanted a solderless set up here for future modification without requiring soldering. While this did add size to the overall device, most of it will be inside TCHeRI's case, and not readily apparent.</p> <p>When left out of the case, and both halves put together, the result looked rather like a Star Trek combadge toy I had as a kid:</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3510 paragraph--type--video paragraph--view-mode--default"> <div class="field field--name-media-video field--type-entity-reference field--label-hidden field__item"> <article class="media media--type-video media--view-mode-default"> <div class="field field--name-field-media-video-file field--type-file field--label-visually_hidden"> <div class="field__label visually-hidden">Video file</div> <div class="field__item"> <video controls="controls" muted="muted" width="640" height="480"> <source src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2022-03/PXL_20220313_050758993.mp4" type="video/mp4" /> </video> </div> </div> </article> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3513 paragraph--type--text-with-image paragraph--view-mode--image-text-50 paragraph--type--text-with-image--view-mode--image-text-50 paragraph--type--text-with-image--order--"> <h2> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="mounting-in-the-case"><h2><a href="#mounting-in-the-case">Mounting in the case</a></h2></div> </h2> <div class="paragraph-text-with-image--body"> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2022/03/27/PXL_20220313_202709512.MP__0.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=U3Hhs5uS 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=n1EgvOu6 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=ikthCUvL 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=n1EgvOu6 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="/s3/files/styles/width_470/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=IwTN3_VJ 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=BL_VS5p_ 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=mBCz7nmq 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=U3Hhs5uS 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=xPK4s1r6 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=ikthCUvL 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=xPK4s1r6 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=mBCz7nmq 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/03/27/PXL_20220313_202709512.MP__0.jpg?itok=xPK4s1r6" alt="The logo mounted on TCHeRI&#039;s plexiglass door" typeof="foaf:Image" /> </picture> </a> </div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>With the logo finished, mounting it in TCHeRI was a simple process of locating where to make the holes in one of the plexiglass doors. Using a bit of poster tape, I positioned the logo on the plexiglass so it would look nice and level. Since I had melted nuts into the logo, finding where to modify the door was as simple as opening the door, locating the nuts, and marking the inside of the door using a sharpie. I could then carefully remove the logo.</p> <p>Like I did with the panels, I used the Pinecil to melt the plexiglass to make the necessary bolt holes. Some careful work with a utility knife blade allowed me to clear away the now unnecessary melted plastic. This created a kind of sandwich: Logo on the outside, plexiglass door, rear case with the LEDs and micro. In a dark room, the entire plexiglass door becomes illuminated with distinct, but understated rainbow colors.

I decided to calculate how much I was spending on web hosting each month compared to how much hardware I'd have to buy to run those sites on a Kubernetes cluster out of my house. Unsurprisingly, the math was damning; the hardware was likely cheaper, even if I bought new hardware every year. Of course, this doesn't factor in time for software updates, materials, energy costs, and other upkeep.</p> <p>I had run my own web server once. The junkbox system ran this site for almost two years, but in the end I decided to go back to third party hosting. This was before SSDs and more powerful single board computers made a powerful counterargument. Factoring those in, as well as the fiber line I have to my house, made me want to try again.</p> <p>Even if it ended up being a silly project, I might learn something from the attempt.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3456 paragraph--type--image-gallery paragraph--view-mode--default paragraph--type--image-gallery--count-4"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="mostly-printed"><h2><a href="#mostly-printed">&quot;Mostly printed&quot;</a></h2></div> <div class="field field--name-field-para-images field--type-image field--label-hidden field__items"> <div class="field__item field__item__1"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2022/01/30/1.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2022/01/30/1.jpg?itok=JzPWdax9 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2022/01/30/1.jpg?itok=0F66kih7 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/01/30/1.jpg?itok=ik2mZy5V 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2022/01/30/1.jpg?itok=0F66kih7 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2022/01/30/1.jpg?itok=PjVNC8nd 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1880/public/2022/01/30/1.jpg?itok=RyR3T8mi 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/01/30/1.jpg?itok=jjSkid3R 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2022/01/30/1.jpg?itok=JzPWdax9 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/01/30/1.jpg?itok=0w_cEpNL 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/01/30/1.jpg?itok=ik2mZy5V 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/01/30/1.jpg?itok=BdL4FO4v 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/01/30/1.jpg?itok=jjSkid3R 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/01/30/1.jpg?itok=0w_cEpNL" alt="A single rail slot Pi holder rests on top of a Pi 400.

did was do some searches on Thingiverse. After some searching I found a <a href="https://www.thingiverse.com/thing:4756812">simple, modular rack</a>. Instead of holding each Pi in a little drawer, it has a sliding mount form which the Pi hangs. Furthermore, each Pi can be paired with a 2.5" SSD for additional, fast storage. The most attractive part was that each part wasn't a long print, meaning I wouldn't need to risk a lengthy, all-night job.</p> <p>Originally, I was going to print all the components in black and red. The chip shortage, however, made Pi 4s difficult to find, although Pi 400s were much more available. I decided to buy one 400 for the kubernetes management node. And since the 400's color scheme was <em>white</em> and red, I decided to print everything in those colors with the plan to also make the case in white too.</p> <p>For power, I decided to use Power Over Ethernet (PoE) and a small PoE network switch to match. This would reduce cabling for the cluster. I slowly started to acquire the hardware for it, eventually <a href="https://www.thingiverse.com/thing:5139533">remixing an existing rack mount</a> for the switch. Instead of buying two switches, I only bought one and used some spare filament to print a dummy switch just to maintain aesthetics.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3459 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="a-compelling-case"><h2><a href="#a-compelling-case">A compelling case</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Originally, I was going to acquire all the hardware for the cluster, print the rack mount components, and then make the rack itself using plywood and other woodworking methods. The more I thought about this, though, the less it seemed to appeal. While building the rack using plywood would allow me to flex other skills, it would also hide all the work I had done for the cluster itself. Furthermore, I didn't know what to use for the rails on which the rack components would mount.</p> <p>The thought occurred to me that instead of the typical L-brackets used in pre-fab racks, I could use aluminum profiles. Also called aluminum extrusions, these profiles had a slot in which you can mount components face on. For this reason, they're popular for 3D printers, and I used them to build the bed of my CNC machine and laser engraver. Building the case out of profiles would allow me to practice more complex construction methods I would hope to use for a future build of a CoreXY 3D printer. I could also use plexy for the sides to show off my work.</p> <p>There was only one problem, I didn't have any profiles left. I did, however, have a 3D printer and a roll of cheap, recycled PLA...</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3458 paragraph--type--image-gallery

either that or waiting.

There was also no need to dispose of the faux-strusions either; they could be torn apart easily and kept around for future prototyping projects.</p> <p>To hold the rack together, I decided to turn again to the 3D printer, and print out mounting brackets and washers to hold everything together.</p></div> </div> </div> <div class="field__item"> <h2></h2> <figure class="paragraph paragraph--id--3461 paragraph--type--image-and-description paragraph--view-mode--image-text-50 paragraph--type--image-and-description--view-mode--image-text-50"> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2022/01/30/9.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/01/30/9.jpg?itok=ZR1ZVc7u 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/01/30/9.jpg?itok=hrMHB4vY 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/01/30/9.jpg?itok=VVpprC2- 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2022/01/30/9.jpg?itok=hrMHB4vY 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_470/public/2022/01/30/9.jpg?itok=SNgDRo0f 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2022/01/30/9.jpg?itok=t4L-TEc5 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/01/30/9.jpg?itok=7U4oYgI9 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2022/01/30/9.jpg?itok=ZR1ZVc7u 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/01/30/9.jpg?itok=G-FD-y0Q 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2022/01/30/9.jpg?itok=VVpprC2- 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/01/30/9.jpg?itok=G-FD-y0Q 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2022/01/30/9.jpg?itok=7U4oYgI9 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2022/01/30/9.jpg?itok=G-FD-y0Q" alt="The proof of concept rack, showing both switches mounted and the Pi rack" typeof="foaf:Image" /> </picture> </a> </div> <figcaption class="field field--name-field-para-description field--type-string-long field--label-hidden field__item">The result was surprisingly good.</figcaption> </figure> </div> <div class="field__item"> <div class="paragraph paragraph--id--3463 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="sometimes-the-simplest-solution-is-best"><h2><a href="#sometimes-the-simplest-solution-is-best">Sometimes the simplest solution is best</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Originally, I was planning on just resting the Pi 400 on top of the rest of the Pi rack.

This size was more necessitated by the print size of my Ender 3 than anything else. 150mm plus the length of bracket needed to mount on the rail easily fit on the print bed. Mirror that, you get a full-width tray. I used blender to design a new tray heavily remixed from an existing option. I printed a pair in the recycled PLA I used for the printed profiles, as I was expecting to order white filament in the future and print final versions.</p> <p>And this is where I ran into another problem. I finally had the budget again to buy real profiles. I was hoping to buy a set and paint them to match the Pi400's color scheme. Aluminum, as I found out, is notoriously difficult to paint. It requires careful cleaning and sanding for paints to adhere. Buying extrusions in my chosen color, unfortunately, where straight out. They required a special order, and, because of the pandemic, had no promise of availability or arrival time. Even if I accepted the risk and painted them myself, it's the dead of winter in Minnesota, and I have no heated garage.</p> <p>Given all of this, I gave up on the idea of a mostly white cluster case, and defaulted to my normal red and black. I haven't decided if I'll reprint the Pi rack itself in black, although that is certainly possible when I have more black filament in the future.</p></div> </div> </div> <div class="field__item"> <div

The PoE switch and the Pi400 all have AC power bricks. While I could just use a conventional power strip, I wanted something more modular for this particular rack. Searches for something suitable online turned up nothing appealing, so I decided to design one myself.</p> <p>To make the job easier, I was only designing the case for the power strip, rather than all the components. I already had the switches and the IEC power ports on hand. All that left was the AC outlets themselves and some wiring. Fortunately, you can order panel-mount AC outlets which are commonly used for office furniture. After several design iterations, I settled on a design that was 170mm wide, 50mm deep, and 70mm tall. Each strip would have three AC outlets with individual switches, and one IEC input with primary switch.</p> <p>In theory, spade connectors would only be necessary to wire everything together with 16 AWG wire. The IEC port also has a built-in fuse for added safety. It's definitely overbuilt for the current requirements I'll be asking of it, but that also means an added margin of safety. AC power is not something to take lightly.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3467 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="more-next-time"><h2><a href="#more-next-time">More next time</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>While there's still lots to go with this project, I want to make an effort to make smaller posts more often.

Many will buy a 3D printer and use it only to make decorative items. While there is absolutely nothing wrong with that, I know I would be ultimately disappointed in a printer as a tool if I were so constrained. The key to unlocking the potential in a 3D printer is if you also can model in 3D.</p> <p>I've modified a few existing designs before. My first was a <a href="https://www.thingiverse.com/thing:4949322">simple bed leveling guide</a> because I simply couldn't remember which way to turn the leveling knobs on my Ender 3 Pro. It was a modification of an existing design, but the project gave me much needed confidence. I followed this with a <a href="https://www.thingiverse.com/thing:5139533">modification of a rack mount for a network switch</a>. Both of these were little more than modifications on a existing project; move this, add a cutout here, shrink this, and so on.</p> <p>Recently, however, I found myself wanting to extend another tool I printed earlier.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3435 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="donuts-over-cookies-pyramids-on-the-side"><h2><a href="#donuts-over-cookies-pyramids-on-the-side">Donuts over cookies, pyramids on the side</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The <a href="https://www.thingiverse.com/thing:3451870">Bench Donut</a> is a kind of multi-purpose workholding tool. It resembles a hockey puck, with the top and bottom flat surfaces covered in a grippy material such as rubber. I didn't have any rubber at the time, so my version used anti-slip cloth which was left in a drawer when I moved into my house. To add more flexibility to the donut, an integrated threaded insert is at the axial center, suitable for an M6 bolt. While 3D printed, the bench donuts are heavy as they are filled with sand. Combined with the grippy surface, this results in a handy workholding solution.</p> <p>I printed 8 of these donuts after receiving a gift of a circular saw. By placing the donuts on the floor, and then a sheet of material to cut on top, you can create sufficient clearance to use the saw anywhere there's a flat and level surface. The few times I've needed to do this sort of operation, the donuts were invaluable. As a bonus, they're so small you can shove them all into a backpack with ease.</p> <p>Another tool I also printed over the last year was a set of "painter's pyramids". These little tools are like the bench donut in that they elevate the work off of any flat surface, Unlike the donut, they also come to a point so as to minimize surface effects on material where finish is drying such as paint. There's a <em>lot</em> of painter's pyramids -- also called painter's triangles -- on Thingiverse. I needed them quickly, so I found the fastest to print design and went with that. The one's I printed worked, but I was ultimately unhappy with them. They were so small they would often move and skitter around the floor. The points were also very, very sharp, and clumsily stepping on one was not an experience I want to repeat.</p> <p>When I had the opportunity to pull out the donuts to cut plywood for my on-going CNC machine project, I found the painter's pyramids right next to them. I couldn't help but think, <em>I can do better</em>.</p> <ul> </ul></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3437 paragraph--type--image-gallery

Commercial versions of this also come with the option of painter's pyramids. Still, I wanted one I could print myself, was open source, and would work with the donuts I had already printed. I opened Blender and started to model an initial version. Thanks to my previous projects, I now had the skills to model something sufficient from scratch. The idea was simple: a blunted pyramid on top of a hollow cylinder which can clip on top of a bench donut.</p> <p>From the start, I wanted to minimize the need for support material in the final print. For this reason, I broke my model into two pieces, a base and the pyramid itself. The modeling process was more straightforward than I imagined now that I was used to Blender's UI:</p> <ol> <li>Create a cube the size of the pyramid.</li> <li>Use the chamfer tool to create a pyramid on one half of the cube with the top still flat.</li> <li>Use the subdivide tool to subdivide the flat top.</li> <li>In edit mode, raise the now very small top polygon to create the blunted tip.</li> <li>Select the bottom of the half-pyramid/half-cube, shortening the cube half as much as possible.</li> <li>Use some more cubes and boolean modifies to create cutouts to reduce filament use.</li> </ol> <p>I went one step further by trying to make space inside the pyramid for an M6 threaded insert I borrowed from another model.

again from scratch. This time, I borrowed a piece from the bench donut itself. Instead of a threaded insert, an M6 bolt or nut could be embedded into the pyramid. To keep that hardware captured, I made a simpler base with a "false nut" on top. This little extrusion would fit in the space for the nut in the pyramid, solving the locating problem.</p> <p>Again, this worked, but it had a new problem. The false nut was tall enough that while a bolt would fit inside with the pyramid seated on the base, a nut would not. I also wasn't entirely fond of requiring glue for this project. I started wishing I could instead connect the pyramid to the base using regular hardware, such as M3 bolts.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3440

I didn't like this, but it was a very small amount of material so I hoped it would be okay. Imagine my surprise when I found out the false nut itself was the other problem.

made, I could tell that others might want more options for building the pyramids. A hardware-less glue-only version would be nice, as it has half the print time of the standard base. I would also want a clip-on version, which eliminates the need for an M6 threaded rod to join the pyramid to the donut securely.</p> <p>The glue-only version was easy. A cylinder the same size as the hardware base, but with four tiny pins on one size. These pins loosely fit in the M3 holes in the pyramid, allowing locating without much additional material.</p> <p>The clip on version required more editing, but it was essentially extending the existing flush model. Then, I used the same method to make the first clip-on version with the updated base. Since I wanted no support material, only the hardware version of the base is available as a clip-on, as one side can be placed flat on the bed.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3446 paragraph--type--image-gallery paragraph--view-mode--default paragraph--type--image-gallery--count-1"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="conclusion"><h2><a href="#conclusion">Conclusion</a></h2></div> <div class="field field--name-field-para-images field--type-image field--label-hidden field__items"> <div class="field__item field__item__1"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/11/28/6.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2021/11/28/6.jpg?itok=98Rf_wnN 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2021/11/28/6.jpg?itok=sNRFGlW- 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/11/28/6.jpg?itok=DHNqPJfW 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2021/11/28/6.jpg?itok=sNRFGlW- 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/11/28/6.jpg?itok=7Dk5Ztsp 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1880/public/2021/11/28/6.jpg?itok=H6SGinqk 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/11/28/6.jpg?itok=btCOBZYz 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2021/11/28/6.jpg?itok=98Rf_wnN 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/11/28/6.jpg?itok=ZYuM_lOD 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/11/28/6.jpg?itok=DHNqPJfW 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/11/28/6.jpg?itok=_A5sPkkg 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/11/28/6.jpg?itok=btCOBZYz 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/11/28/6.jpg?itok=ZYuM_lOD" alt="A completed set of painter&#039;s pyramids, with the original printed pyramids and donuts" typeof="foaf:Image" /> </picture> </a> </div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3447 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Instead of keeping the design to myself, I posted <a href="https://www.thingiverse.com/thing:5148375">the final version on Thingiverse</a> for others to use.

I love the chill in the air, the lighthearted spookiness, and of course, and the decorations. There's something causally morbid about the season which appeals to me deeply. In previous years, I had a set of Trick-or-treat pumpkin baskets that I filled with sand and left on my doorsteps with some repurposed lawn-lights. I had a plastic skeleton posed in my porch.</p> <p>Then 2020 happened. COVID. George Floyd. The Uprising. Somewhere along the way I put away the skeleton and threw out the plastic baskets where were now bleached from UV exposure.</p> <p>This year, I wanted to get back into that a bit, but leverage my interest in electronics and 3D printing. <em>So</em>, I thought, <em>Why not print some pumpkins and put some lights in them?</em></p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3414 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="lets-try-something-different"><h2><a href="#lets-try-something-different">&quot;Let&#039;s try something different&quot;</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Almost all my 3D prints to date have been in Hatchbox filament. Due to<a href="/blog/2021/08/27/3-weeks-jammed-3d-prints-fixed"> my recent jamming issues</a>, I had become unhappy with the choice and decided to try something else. While I could have ordered any number of popular filament brands on Amazon, I wanted to move away from that too and try to order something from a local supplier.</p> <p>I had ordered parts previously from <a href="http://th3dstudio.com/">TH3D</a> and <a href="https://www.fargo3dprinting.com/">Fargo 3D Printing</a>. The latter of which is very much the closer of the two to me geographically. While they don't make filament themselves per se, they are an official supplier for <a href="https://www.3dfuel.com/">3DFuel</a>, a popular local filament producer. One of their key products is "ProPLA" which, after annealing, has more impact strength than ABS.</p> <p>While strength wasn't a key consideration for me in this decorative project, I wanted to give them a try anyways. So, I ordered a roll and went to Thingiverse to find some pumpkins. Unsurprisingly, there were several available, but <a href="https://www.thingiverse.com/thing:2590046">I liked the design of this one the most</a>, as it was hollow, had some cute faces with it already, and it seemed easy enough to design my own if I wanted.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3415 paragraph--type--image-gallery

usually do, shoved it into the printer and printed a <a href="https://www.thingiverse.com/thing:1545913">Calibration Cat</a>. I like the calibration cat as it's a quicker print than the benchy -- a small boat commonly used as a printing test -- and it's a fun little trinket to give away. Unlike standard PLA, this ProPLA required printing at much higher temperatures, almost like ABS. The first calibration cat I printed, however, turned out as good as could be expected for an unknown filament.</p> <p>Still, I wasn't yet ready to accept that the filament was fine and move on to printing some pumpkins. I then turned to the tried-and-true benchy. It's a longer print, but it is definitely a more comprehensive test. Things looked promising at first, but as soon as the print got to the boat's cabin, things went wrong.</p> <p>The extruder was struggling and clicking. All the thin sections on the cabin came out either blobby or weak. One was so weak I could snap off the top with my fingers and little effort. Wasn't this supposed to be better filament? Was I just doing something wrong? Was the printer not up to it? It was already mid-October and I didn't want to spend an entire month troubleshooting as I did before. I needed to get these decorations done at least a week before the 31st.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3417 paragraph--type--image-gallery

After some searching, I came upon <a href="https://teachingtechyt.github.io/calibration.html">Teaching Tech's 3D Printer calibration page</a>. The information on the page itself is generally useful, but the key feature is a series of gcode generators which can be used for practical filament tests. Since I only had an afternoon to spend on this, I focused on the two aspects I felt I could control the most: temperature and retraction.</p> <p>Temperature and retraction can have dramatic effects on the quality of your prints. Too much heat can cause the filament to burn, which can result in jamming. To little heat can result in high backpressure and also lead to jamming. Retraction is a less intuitive parameter. When the print head is moving while not printing, it is best to back off the filament in the extruder, creating a small void inside the nozzle. The key effect of retraction is to control print artifacts like <em>stringing</em>, where hairlike threads of plastic show where the extruder moved from place to place on a print when not laying down plastic. I was hoping that by running these tests, I'd get a better sense of how the ProPLA worked, allowing me to print with a higher rate of success when I moved on to the pumpkins.</p></div> </div> </div> <div class="field__item"> <section id="paragraph-id-3432" class="paragraph paragraph--id--3432 paragraph--type--cta paragraph--view-mode--callout-centered"><div class="field field--name-para-bgimage field--type-image field--label-hidden field__item"></div><div class="cta--callout"><h2><div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="like-what-youre-reading"><h2><a href="#like-what-youre-reading">Like what you&#039;re reading?</a></h2></div></h2><div class="clearfix text-formatted field field--name-para-subtitle field--type-text-long field--label-hidden field__item"><p>Consider donating to us on Ko-fi or subscribing on Patreon!

Anything higher than 1mm of retraction produced good results, although the best results appeared to be at 3mm.<br /> <br /> I assumed I had that sorted, and then reprinted the benchy. The results were even <em>worse</em> than before, including a completely jammed extruder. When I finally managed to get the filament out of it, I found after the toothed gear, the filament seemed to get noticably bigger in diameter. So big, in fact, that the extruder couldn't advance it any more.</p></div> </div> </div> <div class="field__item"> <h2></h2> <figure class="paragraph paragraph--id--3419 paragraph--type--image-and-description paragraph--view-mode--image-text-50 paragraph--type--image-and-description--view-mode--image-text-50"> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/10/31/8.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/10/31/8.jpg?itok=VCWSk8FU 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/10/31/8.jpg?itok=sPX1qmfJ 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/10/31/8.jpg?itok=INpVF2UN 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/10/31/8.jpg?itok=sPX1qmfJ 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="/s3/files/styles/width_470/public/2021/10/31/8.jpg?itok=2oRxF3Yc 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/10/31/8.jpg?itok=ojc2AZgB 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/10/31/8.jpg?itok=rcGxXwdu 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/10/31/8.jpg?itok=VCWSk8FU 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/10/31/8.jpg?itok=xO9XCbDC 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/10/31/8.jpg?itok=INpVF2UN 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/10/31/8.jpg?itok=xO9XCbDC 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/10/31/8.jpg?itok=rcGxXwdu 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/10/31/8.jpg?itok=xO9XCbDC" alt="A skull shaped candle and three small candles all in black wax burns" typeof="foaf:Image" /> </picture> </a> </div> <figcaption class="field field--name-field-para-description field--type-string-long field--label-hidden field__item">Perhaps I should ask the Dark Lords Of Printing for guidance...</figcaption> </figure> </div> <div class="field__item"> <div class="paragraph paragraph--id--3420 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>I decided to do more research, hoping that maybe, someone else was experiencing similar issues as I was. What I learned is that "ProPLA" isn't exactly PLA. It's <em>mostly</em>, PLA with additives and other plastics which can increase its strength. The feel of the plastic right off the spool is notably different than standard PLA, and it should be treated as a specialty filament.</p> <p>One post suggested backing off on the extruder spring (the <em>tensioner</em>) to give the filament a bit more wiggle room against the toothed gear which advances the filament into the hotend. That made sense to me, and I took apart the extruder to try it when I discovered something. My extruder <em>had no way</em> to adjust the spring pressure. In fact, the spring was just captive by two screws, neither of which compressed the spring further to add more tension. Near as I can tell, the aftermarket metal extruder I have was missing a key part which allowed the tensioner to function. When I took apart an unused dual gear extruder, the missing part became apparent.</p> <p>I was about to switch to the dual gear, when I realized that it wouldn't fit on my modified printer. A bolt was in the way. So instead, I decided to borrow the spring from the dual gear extruder, which had more pressure than the one I was currently using. This added more force to the tensioner. While this was the opposite of the advice from the post, it was working from the assumption of at least some tensioner pressure, rather than nearly none as I had.<br /> <br /> The same post also suggested that ProPLA was susceptible to retractions, so I turned off all retractions and printed another benchy.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3421 paragraph--type--image-gallery paragraph--view-mode--default paragraph--type--image-gallery--count-1"> <div class="field field--name-field-para-images field--type-image field--label-hidden field__items"> <div class="field__item field__item__1"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/10/31/9.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2021/10/31/9.jpg?itok=jXfiOjbF 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2021/10/31/9.jpg?itok=DJJN5NVi 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/10/31/9.jpg?itok=HgbuPa9E 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2021/10/31/9.jpg?itok=DJJN5NVi 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="/s3/files/styles/width_940/public/2021/10/31/9.jpg?itok=zyf4zXCL 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1880/public/2021/10/31/9.jpg?itok=oz4nepUf 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/10/31/9.jpg?itok=MDegjeKg 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2021/10/31/9.jpg?itok=jXfiOjbF 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/10/31/9.jpg?itok=vCBrkiJH 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/10/31/9.jpg?itok=HgbuPa9E 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="/s3/files/styles/width_375/public/2021/10/31/9.jpg?itok=0dnjWp_A 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/10/31/9.jpg?itok=MDegjeKg 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/10/31/9.jpg?itok=vCBrkiJH" alt="A completed benchy, stringy, but complete" typeof="foaf:Image" /> </picture> </a> </div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3422 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>While the result was stringy as all heck, it was a complete benchy and showed none of the issues as before.</p> <p>This process took an entire afternoon to sort out, and it didn't seem like either temperature or retraction was the key problem here.

text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>While I sat on that problem, I turned to printing the remaining two pumpkins of my planned four pumpkin set. The remaining faces included with the original Thingiverse design, however, weren't all that appealing. After the last year, I didn't want something too ghoulish. While the included faces were good, I wanted something cuter.</p> <p>I thought about this while sitting with my cat one night and it hit me. I should make my own designs. The Thingiverse design did include a plain back which could be importing into modeling software. I drew up a simple cat face as an SVG in Inkscape, and then imported that as a file into Blender. Using a boolean operator, I cut out the SVG face from the model. Once saved, I could import <em>that</em> into a slicer and send that to the printer.</p> <p>When that worked, another opportunity hit me. One of my favorite games is the <em>Animal Crossing</em><em> </em>series. I've been a fan since <em>New Leaf</em> and found it a good way for me to relax and disconnect. I may be unusual as a player because I'm not terribly interested in the acquisition or design aspects of the game, to me it's more a therapy exercise. So, when Nintendo did provide a template to carve their in-game avatar of Halloween, Jack, I thought, <em>I bet I could print that</em>.</p> <p>Instead of importing the graphic, I did the same process as I did with the cat face. I created the SVG whole cloth, only using the carving template as a reference. Then the same process could be used to create the necessary gcode for the printer. It worked amazingly well, and it's a regret that due to licensing issues, I cannot release the SVG or the STL files for others to print.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3427 paragraph--type--text-with-image paragraph--view-mode--image-text-50 paragraph--type--text-with-image--view-mode--image-text-50 paragraph--type--text-with-image--order--"> <h2> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="hit-the-lights"><h2><a href="#hit-the-lights">&quot;Hit the lights&quot;</a></h2></div> </h2> <div class="paragraph-text-with-image--body"> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/10/31/15.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/10/31/15.jpg?itok=ICFK8MQO 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/10/31/15.jpg?itok=2GhqQrL2 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/10/31/15.jpg?itok=SuDMY4k3 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/10/31/15.jpg?itok=2GhqQrL2 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="/s3/files/styles/width_470/public/2021/10/31/15.jpg?itok=gH_WdetY 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/10/31/15.jpg?itok=J2OHz8YI 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/10/31/15.jpg?itok=eZ1nLWVZ 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/10/31/15.jpg?itok=ICFK8MQO 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/10/31/15.jpg?itok=N1MSrMVa 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/10/31/15.jpg?itok=SuDMY4k3 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/10/31/15.jpg?itok=N1MSrMVa 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/10/31/15.jpg?itok=eZ1nLWVZ 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/10/31/15.jpg?itok=N1MSrMVa" alt="Three LEDs glow on a breadboard connected to a printed battery holder" typeof="foaf:Image" /> </picture> </a> </div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Now I had to solve the lighting issue. I still didn't like my options I found online, nor did I like any I found locally. The natural conclusion I was arriving at was to build them myself. I do have a quantity of LEDs, as well as the parts to construct several "joule thief" circuits capable of lighting them for days and days. But, none of the LEDs I had were multicolored. <em>For that</em>, I thought, <em>I'd need a microcontroller and more money than I'm willing to spend on this project</em>.</p> <p>Then I found out that two wire, multicolor LEDs were a thing. These have the form factor of a single-color LED, but have internal circuitry to change colors only requiring power. I ordered a pack of them for $7 and hooked them up to my prototyped joule thief.</p></div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3428 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>It...didn't work. After talking to some people online, the consensus was that the joule thief wasn't giving the LED enough power, and due to the noisy output, was "resetting" the internal microcontroller of the LED, resulting in them being stuck on the initial red color. I decided instead to just power the LEDs directly, but I'd need more than one AA for each.</p> <p>Getting the batteries wasn't so much of a problem as was the lack of holders for the batteries. I only had ones for a single cell, and not enough to start with. To solve that problem, I turned to 3D printing once more. <a href="https://www.thingiverse.com/thing:456900">This battery holder design</a> only needs some wire for contacts, and uses a clever bit of plastic to provide the spring action to press the contacts against the battery. Instead of soldering each circuit, I bought a set of four tiny, adhesive backed breadboards and set up the light for each. The result was excellent.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3429 paragraph--type--image-gallery paragraph--view-mode--default

Furthermore, I also hung up the skeleton, with some additional lighting which clicks on in darkness.</p> <p>The project wasn't all that complicated in the end, but it was a good learning experience and relied on multiple disciplines to succeed.

Instead of pulling out the phone to buy something, you start wondering, "Can I print that?" As a result, I have a few 3D printed things around the house which otherwise would have been a purchase. Broom holders, wall hooks, a handle for a brush, and a pill crusher are only some examples. It might not save you money, but there is a kind of pride to be found in repeatedly going back to something around the house and remembering, "I made that".</p> <p>The thing is, printing is only half the fun of having a 3D printer.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3396 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="why-mod"><h2><a href="#why-mod">Why mod?</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The first natural question a lot of people have, is, "why bother modifying your printer at all?" Printers, like most things under Capitalism, are <em>compromise devices</em>. They are manufactured with a conflict between how much they cost to manufacture, the features they can provide, and the quality delivered. "Pick two," as the meme goes. Even if it weren't for the pressures of profiteering, there are even some physical limitations which can make a "no compromise" printer impossible. It is my belief that there isn't such a thing as a no compromise printer, but there can be no compromise enough for <em>you</em>.</p> <p>Modifying allows you to impose your own personal context and needs upon the printer, customizing it so that it better suits what you want or need it to do. Those who are deeply invested in printing as a hobby, may even have multiple printers each configured with a particular slant of features such as speed, quality, or build volume.</p> <p>One of the original motivations which led me to the Ender 3 Pro is that it's a fairly inexpensive printer which can be very easily modified. Indeed, there are a lot of commercial or DIY modifications that can be found for it. This allows you to expand the printer's capabilities over time rather than save up for the "ultimate" printer. More important to me is how modding is a challenging learning experience.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3397 paragraph--type--image-gallery

class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The Ender 3 is a <em>bowden tube</em> printer as shipped from the manufacturer. This setup places the extruder stepper motor away from the print head, using a slippery piece of PTFE tubing to route the filament from the motor to the hotend, where the plastic is melted. This is a tried-and-true extruder set-up, and is used on a variety of printers from economical to the elite. It does have a few downsides, however:<br /> <br /> 1. It can only work with rigid filaments and not flexible ones (reliably).<br /> 2. Loading, unloading, and changing the filament can be awkward.<br /> 3. The PTFE tubing must be of high quality, otherwise it can introduce <em>filament drag</em> (excess friction on the filament) which leads to underextrusion.</p> <p>The key advantage, however, is that the heavy stepper motor doesn't have to move with the print head. This can me higher acceleration and print speeds with fewer artifacts such as <em>ringing </em>(repeated artifacts of features such as corners or holes on otherwise flat surfaces). Those who stick to a bowden tube typically trade flexibility for higher print speeds, often to stunning effect.</p> <p>For me, I'm not here to win any speed races. I'd rather have more flexibility and much, much easier loading. Within the Creality enclosure on a 100% stock printer, to say it was awkward to change filament was an understatement. So much so that I often just left the spool of filament in the printer once loaded for months at a time (don't do this).</p> <p>All of this led me to wanting mod the printer to use direct drive. In a direct drive, the stepper motor is as close to the hotend as possible, often moving with the print head on the same assembly. While printed options existed, they often required modifying the printer's firmware to support them, and that was a step too far for me at the time. When I heard about Printermods Modular Direct Drive (MDD), I ordered a kit as soon as the money was available.</p></div> </div> </div> <div class="field__item"> <div class="paragraph

In short, the MDD is, like everything else, a mod which particular compromises in mind. It's optimized for cost and reusing the existing extruder stepper and hotend.

The instructions come with pictures, and you can find several videos online about how to assemble it step by step. Primarily, the kit is a new mounting plate for the gantry slider, with some plastic pieces and hardware to tie it all back together.</p> <p>Disconnect the bowden tube and use the exposed bolts to remove the fan shroud around the hotend. Then unbolt the hotend itself, leaving the gantry slider bare. The trickiest part is knowing and accessing the eccentric nut at the bottom of the slider. This nut isn't concentric with the axis of rotation, but offset. This allows the normal nut tightening action not only to go down along the bolt, but side to side. In the Ender 3, it's used to tighten one of the roller wheels against the aluminum extrusion which makes up the gantry. Remove the old slider, transfer the wheels to the new backing plate, put it back on the gantry.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3401

installed, you need to move the existing extruder motor to the plate. This involves unbolting it from the existing mounting bracket. You could then replace it, unchanged, onto the new direct drive mount. One thing that occurred to me while doing all of this was to do other smaller upgrades while I was at it.</p> <p>The MDD instructions actually request to inspect the extruder arm carefully once you have it off the printer. The stock extruder is made of plastic, and the tensioner arm is known to crack and break over time. While mine did not have this issue, I did decide to upgrade the existing extruder for one made of metal.</p> <p>During disassembly, I noticed some plastic shavings. This is a telltale sign that the extruder had been grinding at some point. This happens when there's sufficient pressure on the filament as it moves through the entire extruder assembly that the toothed gear "skips" on the filament as it tries to advance it. And, if I recall, the printer was in fact jammed at this time after operating for months without fault.</p> <p>I didn't buy any special kind of extruder for my replacement, but whatever was popular online. While it didn't come with instructions, once I had disassembled the previous extruder, putting the new one together was a simple enough task.</p></div> </div> </div> <div class="field__item"> <div

that came with the Ender 3. This hotend requires a length of PTFE tubing in it from the blunt end of the nozzle to the extruder. This length of tubing is very short and straight, so it still allows more force to be transferred from the extruder to the hotend with less drag than a full bowden tube.</p> <p>Of course, the first thing I needed to do was get the tube <em>out</em>. As I mentioned above, the printer was jammed at the time, the first time it had jammed in all the months I had been using it at this point. Since this was the first time I was disassembling it, it didn't occur to me to disassemble the hotend with it hot, as is recommended. Instead, I tugged and pryed on it until finally, the tube came out. I was lucky I didn't damage the hotend with all that violence.</p> <p>Once the tube was out, it found it to be a filthy mess. The entire surface was sticky, with a glob of unidentified stuff at the top, and a blacked mass clogging the end of the tube. Furthermore, the tube itself was clogged. I could just cut off the damaged sections, but PrinterMod's included a short length of PTFE with the kit, so I intended to use that.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3405 paragraph--type--text-with-image paragraph--view-mode--text-image-50 paragraph--type--text-with-image--view-mode--text-image-50 paragraph--type--text-with-image--order--"> <h2></h2> <div class="paragraph-text-with-image--body"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Worse, though, was the nozzle itself appeared to be clogged. This is actually normal, and fortunately, the Ender 3 comes with a small bag of spare nozzles just in case. The bigger problem was the heatbreak.</p> <p>The heatbreak is a short length of stiff metal tube between the heatsink and the heater block. The purpose is to keep the heat from the heater block in the heater block (to "break" it) and not have it travel up into the heat sink where plastic would melt prematurely. When I pulled out the PTFE tube, it was a sticky mess, so presumably, was the inside of the heatbreak.</p> <p>While I had spare nozzles, I didn't have any spare heatbreaks, so I decided to try to clean it by soaking it in acetone. After the inside was reasonably clean, I could reassemble the hotend and mount it on the gantry slider plate. A small but key step is to include the plastic spacer that keeps the heatsink from being completely flush with the plate.</p></div> <div class="field field--name-field-para-image field--type-image

Auto Bed Leveling (ABL) sensor. The one I chose was a BLTouch, from Creality's official kit. This was actually a thank you gift from a tech conference I spoke at, Florida Drupal Camp. While Florida is just not my jam, I love that camp. It's always been an enjoyable and enlightening experience and I hope to go back again in the future.</p> <p>At the time, I knew I couldn't get the BLTouch working, since this would require firmware changes I wasn't ready yet to tackle. But since I did have the hotend in pieces, I might as well physically install it.</p> <p>Creality's BLTouch kit has a small mounting bracket with the same mounting holes as the fan shroud. Once you mount the BLTouch sensor, you put the bracket, and the fan shroud back on the gantry assembly at the same time. It's...clumsy to say the least. After a few tries you do get the hang of it.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3408 paragraph--type--image-gallery paragraph--view-mode--default

the printer components, with only changes in mounting brackets to facilitate it. Nevertheless, I was still overjoyed when flipped the printer back on, heated it, and began pushing filament through it.</p> <p>After re-leveling the bed, I decided to print one of my favorite test prints, a "<a href="https://www.thingiverse.com/thing:1545913">calibration cat</a>". I love this print as it's both useful as a calibration device, as well as cute and a nice little trinket to give away to friends. The print turned out flawlessly on several different filaments, and the results compared identically with previous prints I made of the same model with the stock printer.</p> <p>The filament path was now much more direct than the original bowden setup. As recommended, I removed the spool holder and flipped it around so the roll was in line with the gantry. Now, I only needed to drag down the filament from the spool and insert it into the extruder head. This was a massive improvement for loading and changing filament, particularly from within an enclosure. Everything was now front-loaded, the only complication being that the extruder gearing was facing toward the rear of the printer. In practice, this is only a problem when the printer jams. It's better to remove the extruder stepper motor and not disassemble the hotend to clear it. This is awkward, but less fiddly than removing the hotend.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3410 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="summary"><h2><a href="#summary">Summary</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>I can't tell you which mods to do on your printer.

It simplified filament changeovers, while expanding the capabilities of the printer.</p> <p>While the heavier extruder head can create more artifacts with printing, I haven't found the ringing to be significantly bad enough on my modified printer to worry about it, even at speeds up to 100mm/s.</p> <p>Next time, we'll get that BLTouch working, but we'll do more than that.

tricorder was complete, I tried to print something else. While the print looked like it was starting okay, within the first 20 or so layers it would start showing a familiar pattern of failure. The filament wasn't bonding well with the other layers, resulting in a weak print. Worse, now the printer wasn't "working it through', but completely jammed. The extruder gear would eventually wear through the filament and now nothing would print.</p> <p>Again, I assumed the problem might just be transient. Ender 3s, such as mine, are prone to jamming issues and it's a surprise I hadn't encountered the problem before in previous year or so of printing. Since my printer has been modified from stock using <a href="https://printermods.com/products/direct-drive-mod-for-creality-ender-3-cr-10">Printermod's Modular Direct Drive (MDD) kit</a>, there was little filament to grab a hold of to clear the jam. I had no choice but to take the hotend apart to clear it.</p> <p>This wasn't the first time I had taken the hotend apart. I had to do so to install the MDD in the first place, and took the opportunity to replace the heatbreak and the nozzle.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3377 paragraph--type--text-with-image paragraph--view-mode--image-text-50 paragraph--type--text-with-image--view-mode--image-text-50 paragraph--type--text-with-image--order--"> <h2> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="how-is-a-hotend-built"><h2><a href="#how-is-a-hotend-built">How is a hotend built?</a></h2></div> </h2> <div class="paragraph-text-with-image--body"> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/08/27/mk8_hotend.png"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/27/mk8_hotend.png?itok=CoOKArBn 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/27/mk8_hotend.png?itok=aZqSS_FB 2x" media="all and (min-width: 1200px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/27/mk8_hotend.png?itok=a0lTST_x 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/27/mk8_hotend.png?itok=aZqSS_FB 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_470/public/2021/08/27/mk8_hotend.png?itok=-M2FL7Th 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/08/27/mk8_hotend.png?itok=VJ3IyV-w 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/27/mk8_hotend.png?itok=fK0N9VdC 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/27/mk8_hotend.png?itok=CoOKArBn 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/27/mk8_hotend.png?itok=mrNglk0K 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/27/mk8_hotend.png?itok=a0lTST_x 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/27/mk8_hotend.png?itok=mrNglk0K 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/27/mk8_hotend.png?itok=fK0N9VdC 2x" media="all and (max-width: 319px)" type="image/png"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/27/mk8_hotend.png?itok=mrNglk0K" alt="A diagram of the MK8 hotend" typeof="foaf:Image" /> </picture> </a> </div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The Ender 3 uses an "MK 8" hotend. This hotend is fairly common and generally effective, but it does have a... Let's not say a "design flaw", but more of a design compromise. It requires a section of high-temperature PTFE tubing to extend all the way down the hotend to the tip of the nozzle. Depending on your printer set up, that PTFE tube can be fairly short -- as it is for my direct drive printer -- or longer in a "bowden tube" setup.</p> <p>Of course, the nozzle and PTFE aren't just floating in air, there's an entire hotend assembly around it. Directly above the nozzle and surrounding the tube is the heatbreak, a rigid metal pipe. The goal of the heatbreak is to separate ("break") the very hot heater block from cooling heatsink.</p> <p>When printing, the filament travels down the PTFE tube, through the heatsink, heatbreak, and into the nozzle. Toward the bottom of the heatbreak, the filament enters the <em>melt zone</em> in the heater block. Structurally, the nozzle and heat break are screwed into threads in the heater block. The heatbreak is retained in the heatsink via small screws which pin it in place.</p> <p>As the extruder motor pushes filament into the hotend assembly, the plastic melts as near to the nozzle as possible, and is pushed out the aperture to the print. At least, that's how it's supposed to work, in theory.</p></div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3378 paragraph--type--image-gallery

field__item"><p>The MK8 hotend is rather particular in how it likes to be reassembled, there are two very common failure modes for this hotend.</p> <p>The first is that the nozzle and the heatbreak are not fully seated against each other. This creates a gap between the two in the melt zone in which plastic can get stuck. Typically, this results in the hotend leaking, as melted plastic will travel up the hotend threads, or down the nozzle threads creating a globby mess.</p> <p>The other failure is a little more subtle. This time, the nozzle and heatbreak are firmly seated against each other. Yet, the PTFE tube is <em>not</em> seated fully against the nozzle. This creates another gap in which melted plastic can get stuck. This plastic may not escape the hotend, but are instead constantly rolled around inside out in a little donut shape. Since it's heated for so long, the plastic burns, chars, and creates additional resistance the extruder motor has to overcome. This is called <em>filament drag</em>, and it's very, very common for the original Ender 3, although less so for the Ender 3 Pro such as mine.</p> <p>I was sure that filament drag was the problem, and at first, it was. I didn't know how to assemble the hotend properly, and only lucked out when I did the MDD mod. The second time was a leaky disaster due to improper seating of the nozzle and heatbreak. The third and fourth time I cleared and reassembled the hotend, I was working to mitigate the bowden gap.</p></div> </div> </div> <div class="field__item"> <section id="paragraph-id-3394" class="paragraph paragraph--id--3394 paragraph--type--cta paragraph--view-mode--callout-centered"><div class="field field--name-para-bgimage field--type-image field--label-hidden field__item"></div><div class="cta--callout"><h2><div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="like-what-youre-reading"><h2><a href="#like-what-youre-reading">Like what you&#039;re reading</a></h2></div></h2><div class="clearfix text-formatted field field--name-para-subtitle field--type-text-long field--label-hidden field__item"><p>Consider supporting us.

Most advocate for pressing the PTFE tube in prior to securing it in the fitting using a small C clip. My problem was my printer was direct drive. The MDD mod made most of those techniques impossible due to the extruder motor was in the way, barely leaving a gap for fingers between the bottom of the motor and the fitting.</p> <p>After two more failed prints, I went back and tried to research another solution. <a href="https://www.youtube.com/watch?v=7tCxO17XZtw">A popular method</a> is to split the PTFE into two parts, and install a small printed washer just under the fitting. The fitting can then press against the washer and thus the short length of PTFE. This closes the boden gap, and allows for play in the PTFE tube leaving the hotend. This would <em>probably </em>work for my modified printer, but I was concerned about the washer melting if there was a cooling issue.</p> <p>Since the PTFE is so short in my printer, a simpler idea came to mind. Instead of separating the PTFE into two pieces, I could do the same thing I did with the nozzle. I could install the fitting snugly into the heatsink, then back it off one whole turn. This done, I could then install the PTFE, add the retaining clip to hold the PTFE in place, and then tighten down the fitting.</p> <p>This done, I hoped that finally the jamming issue was behind me.</p></div> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/08/27/mk8_hotend_extruder_0.png"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/27/mk8_hotend_extruder_0.png?itok=nPyLKTrm 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/27/mk8_hotend_extruder_0.png?itok=ZWAQG1_6 2x" media="all and (min-width: 1200px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/27/mk8_hotend_extruder_0.png?itok=4uP6GP2t 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/27/mk8_hotend_extruder_0.png?itok=ZWAQG1_6 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_470/public/2021/08/27/mk8_hotend_extruder_0.png?itok=fru2fP5x 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/08/27/mk8_hotend_extruder_0.png?itok=zogrSjqL 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/27/mk8_hotend_extruder_0.png?itok=kNCh2Odh 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/27/mk8_hotend_extruder_0.png?itok=nPyLKTrm 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/27/mk8_hotend_extruder_0.png?itok=RxzRbKiQ 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/27/mk8_hotend_extruder_0.png?itok=4uP6GP2t 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/27/mk8_hotend_extruder_0.png?itok=RxzRbKiQ 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/27/mk8_hotend_extruder_0.png?itok=kNCh2Odh 2x" media="all and (max-width: 319px)" type="image/png"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/27/mk8_hotend_extruder_0.png?itok=RxzRbKiQ" alt="A diagram of the hotend assembly, with the addition of filament and the extruder" typeof="foaf:Image" /> </picture> </a> </div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3382 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="it-wasnt"><h2><a href="#it-wasnt">It wasn&#039;t</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>While the first few calibration prints worked well and completed successfully, anything more jammed.

A lot of the symptoms I was getting suggested a temperature problem, yet the printer's own readout seemed relatively stable. It "wobbled" a little when changing temperature, but eventually stabilized. Octoprint told a different story. There was significant oscillation in the temperature, but rarely larger than 1C.</p> <p>There are two components in a 3D printer which control the hotend temperature. The first is the heater cartridge, the second is a thermistor. This last component monitors the temperature of the heater cartridge, allowing the printer's mainboard to control the temperature of the hotend. The thermistor in an Ender 3 is basically a temperature controlled resistor, if it returned inaccurate values, the printer would think it was up to temperature, but could be much hotter or colder.</p> <p>I needed a second opinion, and luckily, I had one available.</p> <p>My multimeter came with a temperature probe, so I took it out and put it against the hotend. To my surprise, the readings were wrong; 20C at the lower operating temperature of the printer, 40C at the higher end, and 30C in the middle. A lower temperature would mean the filament wouldn't melt as easily or as quickly, forcing the extruder to work harder, eventually resulting in a jam.</p> <p>"That's it!" I placed an order to replace both the heater cartridge and the thermistor and waited for several days.</p> <p>But something nagged at me...</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3385 paragraph--type--image-gallery paragraph--view-mode--default paragraph--type--image-gallery--count-1"> <div class="field field--name-field-para-images field--type-image field--label-hidden field__items"> <div class="field__item field__item__1"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/08/27/PXL_20210813_210029655_0.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=y-_Kxvct 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=qk5lCQ-5 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=xnI0l1yZ 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_2400/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=qk5lCQ-5 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=s7RD2Z-C 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1880/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=fKitV0UT 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=ui0h5o80 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1500/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=y-_Kxvct 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=Uv7Dv3_U 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=xnI0l1yZ 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=azvLudpS 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=ui0h5o80 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/27/PXL_20210813_210029655_0.jpg?itok=Uv7Dv3_U" alt="A multimeter takes another reading from the hotend, this time only a few degrees off" typeof="foaf:Image" /> </picture> </a> </div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3386 paragraph--type--text paragraph--view-mode--default"> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>My knowledge of electronics is servicable, but it comes mostly from books and not experience.

I removed the silicone sock which insulates the heater block and removed the retaining screw which holds the thermistor in place. I put the multimeter's probe into the screw hole and waited.</p> <p>The results were damning. Instead of 30C off, it was only 4C. The themistor was never the problem.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3387 paragraph--type--image-gallery paragraph--view-mode--default

It certainly works, but it comes with some drawbacks. The biggest of which is that the stepper motor for the extruder is facing away from you and toward the back of the printer. While you can check it with an inspection mirror -- and I did check it multiple times -- it's still easy to miss issues simply due to the motor's orientation. Furthermore, the orientation also discourages you from removing the extruder to service it, as the bolts which hold it on to the gantry are...you guessed it...facing away from you.</p> <p>I pulled the printer out of the enclosure and began to remove the extruder assembly. As soon as I had a direct line of sight, I spotted two new problems I had missed again and again since the jamming began.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3389 paragraph--type--text-with-image paragraph--view-mode--image-text-50 paragraph--type--text-with-image--view-mode--image-text-50 paragraph--type--text-with-image--order--"> <h2></h2> <div class="paragraph-text-with-image--body"> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/08/28/mk8_hotend_upperGap.png"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/28/mk8_hotend_upperGap.png?itok=QF39cSRI 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/28/mk8_hotend_upperGap.png?itok=yI3-kntt 2x" media="all and (min-width: 1200px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/28/mk8_hotend_upperGap.png?itok=bMXYfML5 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/28/mk8_hotend_upperGap.png?itok=yI3-kntt 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_470/public/2021/08/28/mk8_hotend_upperGap.png?itok=m1Qs__Z4 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/08/28/mk8_hotend_upperGap.png?itok=3eaj68Pv 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/28/mk8_hotend_upperGap.png?itok=oSm-guxm 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/28/mk8_hotend_upperGap.png?itok=QF39cSRI 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/28/mk8_hotend_upperGap.png?itok=HtDjvyvc 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/28/mk8_hotend_upperGap.png?itok=bMXYfML5 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/png"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/28/mk8_hotend_upperGap.png?itok=HtDjvyvc 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/28/mk8_hotend_upperGap.png?itok=oSm-guxm 2x" media="all and (max-width: 319px)" type="image/png"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/28/mk8_hotend_upperGap.png?itok=HtDjvyvc" alt="The extruder diagram, showing an upper bowden gap" typeof="foaf:Image" /> </picture> </a> </div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The MDD requires a short length of PTFE from the nozzle to the extruder assembly to guide the filament through to the nozzle. We already know the PTFE-nozzle junction is critical to avoid jamming. I had assumed the other side wasn't that picky at all.</p> <p>It turns out, I was wrong.</p> <p>The MDD reuses the stock extruder. The stock extruder typically expects a bowden tube set up with a fitting to hold a length of PFTE from the extruder assembly to the hotend. In a direct drive set up, this length is much, much shorter. Yet, the extruder still has a exit port with room for a PTFE fitting, rather than just a bit of PTFE. There's no room between the extruder assembly and the hotend to use both fittings, and the MDD's own installation instructions recommend leaving the fitting <em>off</em> of the extruder.</p> <p>Because of this, it can create a secondary bowden gap between the PTFE and the extruder if the PTFE isn't long enough. Rather than melting, it's possible for the filament to kink up and twist within the gap, lodging itself in there and creating additional filament drag. Worse, this failure mode is completely undetectable without disassembling the extruder assembly completely.</p> <p>A possible solution would be to use a different extruder more suited to direct drive, or modify a PTFE fitting to narrow the exit port of the extruder to eliminate the play. Either way, it doesn't solve the much more vexing issue that the extruder motor and gearing is facing the <em>rear</em> of the printer, making this an ongoing hazard.</p></div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3390 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="so-that-was-it-right"><h2><a href="#so-that-was-it-right">So, that was it, right!?</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>Before reinstalling the extruder assembly, I validated that the inside of the hotend was perfectly clear. Again, the MDD doesn't help here since the extruder assembly is completely in the way. Once back together, I started another print and hoped it wouldn't jam this time.</p> <p>As you can guess, my luck was poor, and soon the printer was jammed up once more.</p> <p>I had been fighting this issue for weeks at this point, felt I covered nearly every possibility short of replacing the entire gantry assembly, and <em>still</em> the damn thing was jamming.</p> <p>With no other options, I decided to sit in front of the printer and watch it print, maybe something would stand out. After an hour of watching the printer and hearing the extruder continue to struggle, I did begin to notice something. Every time the printer advanced, it would tug at the filament spool. I had replaced the spool holder from a fixed model which comes with the machine, to one with bearings to remove a possible source of drag.</p> <p>And yes, it did remove the drag...and also uncovered another issue. The filament spool, no longer held back by the friction of the stationary roller, would advance considerably, and the filament would twist and curl around itself. Even if it didn't catch on any moving part, the twisting required more work on the part of the extruder. Worse, as I watched it print, I saw the filament twist get worse and worse. Since the filament was no longer under tension when coming off the roll, the twist never made it to the hotend and was melted away. Instead, it propagated up the roll to join any other twists which were already present in the filament as it came off the spool.</p> <p>I removed the spool several time while the print continued, trying to undo the twist, but eventually I decided to just put a piece of tape over the roller bearings -- essentially changing it back to a stationary roller -- so that the filament would remain under tension. After a few tense layers, printing got easier.

The sparkle black filament I was printing was PLA, so I had assumed it had the same melt temperature as all the other PLA I had bought from the same manufacturer.</p> <p>It wasn't. Instead, it was 20C higher. My typical PLA temperature of 200C was at the low limit of it's melt range, and with my printer's thermistor running 4C cold, it wasn't high enough. I increased the temperature another 30C to the upper limit of the filament's range.</p> <p>Since then, no issues. An overnight print ran successfully, then another all day print. Then a week's worth. Since then, I still have occasional clicking from the extruder, but it hasn't resulted in any failed prints. My filament is in poor shape, however, and I have significant stringing in nearly all my prints now. That's a problem for another post.</p></div> <div class="field field--name-field-para-image field--type-image field--label-hidden field__item"> <a href="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/2021/08/28/PXL_20210814_195828203.jpg"> <picture> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/28/PXL_20210814_195828203.jpg?itok=4zhohGIN 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/28/PXL_20210814_195828203.jpg?itok=2ii2Wv6T 2x" media="all and (min-width: 1200px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/28/PXL_20210814_195828203.jpg?itok=9mbyySb8 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_1200/public/2021/08/28/PXL_20210814_195828203.jpg?itok=2ii2Wv6T 2x" media="all and (min-width: 992px) and (max-width: 1199px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_470/public/2021/08/28/PXL_20210814_195828203.jpg?itok=ibbgWou9 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_940/public/2021/08/28/PXL_20210814_195828203.jpg?itok=YkFBFtFd 2x" media="all and (min-width: 768px) and (max-width: 991px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/28/PXL_20210814_195828203.jpg?itok=RoEF3iYl 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_750/public/2021/08/28/PXL_20210814_195828203.jpg?itok=4zhohGIN 2x" media="all and (min-width: 576px) and (max-width: 767px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/28/PXL_20210814_195828203.jpg?itok=84CiyfMT 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_600/public/2021/08/28/PXL_20210814_195828203.jpg?itok=9mbyySb8 2x" media="all and (min-width: 320px) and (max-width: 575px)" type="image/jpeg"/> <source srcset="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/28/PXL_20210814_195828203.jpg?itok=84CiyfMT 1x, https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_375/public/2021/08/28/PXL_20210814_195828203.jpg?itok=RoEF3iYl 2x" media="all and (max-width: 319px)" type="image/jpeg"/> <img src="https://deninet-live.nyc3.cdn.digitaloceanspaces.com/deninet.com/files/styles/width_300/public/2021/08/28/PXL_20210814_195828203.jpg?itok=84CiyfMT" alt="A closeup of a filament roll label, showing specifications." typeof="foaf:Image" /> </picture> </a> </div> </div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3392 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="conclusion"><h2><a href="#conclusion">Conclusion</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>The last few weeks were the most challenging I've had in my 3D Printing journey. Not only was the jamming issue vexing, but having the source of the jamming result from so. many. little. factors. was astonishing. A hotend gap, a dirty and jammed extruder, mods I made to the printer, combined with issues with the filament itself all contributed to the repeated print failures.</p> <p>If I had the choice to make again, I would likely not want to use the MDD. It's a good mod, and certainly accomplishes the goal of making an Ender 3 direct drive on the cheap. Yet, it isn't working well for me due to my use of an enclosure. I may modify my printer again in the future to use a different gantry assembly which faces the front of the printer.</p> <p>While the experience has been frustrating, I learned a astonishing amount about hotends, how they're built, serviced, and their failure modes. I have to remind myself that printing is merely a side benefit, and learning is what I'm here for.</p></div> </div> </div> <div class="field__item"> <div class="paragraph paragraph--id--3393 paragraph--type--text paragraph--view-mode--default"> <div class="field field--name-field-para-title field--type-string field--label-hidden field__item" id="thanks-to-my-sponsors"><h2><a href="#thanks-to-my-sponsors">Thanks to my sponsors!</a></h2></div> <div class="clearfix text-formatted field field--name-field-para-text field--type-text-long field--label-hidden field__item"><p>This post was created with the support of my wonderful supporters on <a href="https://www.patreon.com/">Patreon</a>.</p> <p>If you like this post, consider becoming a supporter at:</p> <ul> <li><a href="https://ko-fi.com/socketwench">ko-fi.com/socketwench</a></li> <li><a href="https://liberapay.com/socketwench/donate">liberapay.com/socketwench</a></li> <li><a href="https://www.patreon.com/socketwench">patreon.com/socketwench</a></li> </ul> <p>Thank you!!!</p></div> </div> </div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-hidden field__item"><a href="/topic/3d-printing" hreflang="en">3D Printing</a></div> <div class="field field--name-field-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/tag/3d-printing" hreflang="en">3D printing</a></div> <div class="field__item"><a href="/tag/diy" hreflang="en">DIY</a></div> <div class="field__item"><a href="/tag/troubleshooting" hreflang="en">troubleshooting</a></div> <div class="field__item"><a href="/tag/patreon-supported" hreflang="en">patreon supported</a></div> </div> Fri, 27 Aug 2021 16:22:10 +0000 socketwench 1688 at https://deninet.com
