Slim X Axis Cable Chain with Extruder and Hotend Mount for Ender 3 Pro

thingiverse

*****Please post your makes and report your issues, thanks***** <h2>Slim X Axis Cable Chain for Ender 3 Pro</h2> *****READ INSTRUCTIONS BELOW***** _________________________________ <b>Full Z-heigt</b> <b>Full X-width</b> <b>No supports for printing</b> <b>Great filament guide</b> <b>Absolute clean design</b> <i>Be careful when printing on full height, there may be some conflict from the cable chain with the ptfe-tubing!!!</i> __________________________________ **UPDATE 27. July 2020** I renamed the extruder-mounts and added versions for dual-drive extruder and 32mm. **UPDATE 29. June 2020** I replaced the hotend mount with a new version that has a tighter fit. This should prevent it from getting loose or making ratling noise. **UPDATE 8. May 2020** I replaced the extruder mounts with new ones to fit different machines perfectly (with stock and accesorie extruder). Simply measure the distance between the edge of the extruder/bracket to the outer diameter of the leadscrewnut to determine, which one you need. (See the picture) **UPDATE 1. May 2020** <s>I just added an alternative extruder mount for 0.5mm more clearence if your z-nut/rod is closer to the aluminium profile and the original would not fit. (Thanks @Manderlindli for reporting this issue)</s> **UPDATE 28. April 2020** I just added an alternative extruder mount for better fit with the stock extruder. The original still works! But its pushed down a little by the cable claw. The new one has a cutout for the claw. __________________________________ <h2>Y Axis and Z Axis - Heated Bed and Extruder</h2> I used the cable chain parts for the other axis from: https://www.thingiverse.com/thing:2920060 And the cable links from: https://www.thingiverse.com/thing:3491926 (do not use his bed spacers and mount!!!) __________________________________ **Why i designed this!** I am new into 3d-Printing and just got an Ender 3 Pro a month ago. I wanted a clean printer with no cables hanging around. The design from johnniewhiskey is great. But i also wanted to add a cable chain on the x-axis. I tried some extruder and hotend mountings and it worked but i was not satisfied. I searched on Thingiverse for a design. But there is no design i know that allows to move the z-axis to 250mm. There is no design that prints without support. There are great designs for mounting the cable chain on the front, BUT it can be a pain to install it because of the cable lenght and routing. __________________________________ <h1>Instructions</h1> <h2>Requirements</h2> <h3>Material</h3> 6x slim cable ties (mine were 1mm x 2.5mm) 1x m6 push fit (optional, came as a spare) 1x piece of ptfe-tube about 25mm long (optional, cut it from your bowden) <h3>Tools (all shipped with the ender)</h3> blue cuter allen keys wrench <h3>Print</h3> 1x hotend mount 1x extruder mount 16x slim links 16x slim link covers *Choosing the extruder mount: Remove one screw of the leadscrewnut and the extruder spring. Measure the distance between the edge of the extruder/bracket to the outer diameter of the leadscrewnut (Photo). The measured distance coresponds to the name of the file you need. The tolarance is about +/- 0.75mm There are three versions for each distance: <b>stock</b> for the stock plastic extruder with the claw on the side <b>alu</b> for the silver or red aluminium extruder with single drive and idlerwheel <b>alu-dd</b> for the red aluminium extruder with dual drive gears (bond-tech)* 0.2 layer height, 3 perimeters, 20% Infill (Honeycomb) Cable chain from thingiverse for Y and Z axis. As mentioned above. >I used the cable chain parts for the other axis from: >https://www.thingiverse.com/thing:2920060 > >And the cable links from: >https://www.thingiverse.com/thing:3491926 (do not use his bed spacers and mount!!!) <h2>Installation</h2> <h3>Preparation</h3> Make shure all the links are moving freely. Especially at the mountings! <h3>#1</h3> Cut the cable ties that hold the tube and the cables together. Remove the filament out of your system. <h3>#2</h3> Unscrew the springt and remove it from the extruder. Remove the extruder lever. <h3>#3</h3> Install the hotend-mount and secure the cable with cable ties. Install the slim cable links with covers (16x) on the cable and attach it to the hotend-mount. <h3>#4</h3> Unscrew the two bolts from the lead-screw-nut and take them apart. Pay attention not to loose the 4 smal spring washers. The lead-screw-nut must rest in place! <h3>#4</h3> Guide the extruder-mount over your lead-screw. Place your cable on the inside of the extruder-mount and add some cable ties, do not tighten them yet! <h3>#5</h3> Wiggle the extruder mount in place. If you have the stock extruder pay attention to the cable claws (pictures) and guide it in there first. <h3>#6</h3> Reinsert the two screws for the lead-screw-nut to secure the extruder mount. Allign the mount before thightening. IMPORTANT: Only use the 2 spring washers on the bottom! If you have proper alignment of your complete Z-rod and extruder bracket you can assemble it without the spring washers <h3>#7</h3> Attach the cable chain on the extruder mount and secure the cable ties next to the x-axis. Make sure ther cable is not too tight or too lose in the chain. Secure the lower cable ties for the z-chain. <h3>#8 (optional)</h3> Screw in the ptfe-push-fit and add some tubing. You may could remove any printed filament guide on top of the printer. <h3>#9</h3> Reasemble your extruder in the oposite direction. The lever first and then the spring. <h3>#10</h3> Add cable chain for your z-axis. As mentioned above. Whatch picture for routing the cables.
