Ender 3 Y-axis Idler Assm for Motor Relocation

prusaprinters

<p>So I wanted to put on a larger motor and a dampener for the y and x-axis on my Ender 3. Turns out the motor was far too big and when I went to make a whole new bracket I had an idea: just flip the Y-axis bracket vertically and mount that way.</p> <p>The new stepper clears the bed leveling knobs by a few millimeters with the plate upside down but I now needed a new Idler pulley system to keep it from catching on the 2040 bar and seeing as I have a number of GT2 pulleys sitting around from my HEVO build, I decided to put them to good use. Its always good to have spare GT2 belt pulleys around.</p> <p>Final Parts List:</p> <p>M3x16 machine screws (designed for socket-cap style) : 2 count</p> <p>M3 Hex Nuts : 2 count <a href="https://www.amazon.com/dp/B01H3DSGAC/">GT2 20t Toothed Idler Pulley, 3mm ID</a> : 1 count <a href="https://www.amazon.com/dp/B07BPHPYTN/">1 GT2 16t Smooth Idler Pulley, 3mm ID</a> : 1 count <a href="https://www.amazon.com/dp/B01MRVXQ3Y/">GT2 Belt</a> : approx. 30.0625" (30 1/16 inches) or 764 mm length <a href="https://www.thingiverse.com/thing:2814851">GT2 End Crimp</a> : 2 Count</p> <p>Its been in use for over 40 hours of print time now. Hasnt failed and actually helped reduce my Y-axis ringing I was having (0.9°/step motor with more torque might have helped too...). All the links in the parts list are listed in custom section as well for those who hate blind links.</p> <p>13MAR21 Edit: Was having some squeaking issues where the bearing seals on the idlers were rubbing against the part, so I reduced the height of the standoff nubs to allow for some play. Also cleaned up the 2040 profile horns.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>15% Gyroid</p></div> <p><strong>Filament:</strong> <a href="http://www.amazon.com/s?url=search-alias&amp;field-keywords=Overture+PETG">Overture PETG</a> Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Need supports for the 2040 profile overhangs sadly</p></div> Custom Section ============== <p><strong>Amazon Links to parts from Parts List</strong></p> <div><p>Belt: <a href="https://www.amazon.com/dp/B01MRVXQ3Y/" rel="nofollow">https://www.amazon.com/dp/B01MRVXQ3Y/</a></p> 20t Pulleys: <https: b01h3dsgac="" dp="" www.amazon.com=""></https:> <p>16 toothless pulley: <a href="https://www.amazon.com/dp/B07BPHPYTN">https://www.amazon.com/dp/B07BPHPYTN</a></p> </div></p></p></p> Category: 3D Printer Parts
