MK3 / MK3S Extruder upgrade for flexible materials

prusaprinters

<p>Finally, after great response, I ported the files to the platform they belong to.</p> <p>makes higher printing speeds at flexible materials possible, retraction should work too.</p> <p>Main changes to the original:</p> <ul> <li>shifted stepper position to corrected filament path</li> <li>shifted idler position to correct filament path</li> <li>constructed a filament guide to stop the filament from popping out the extruder</li> </ul> <h3>Print instructions</h3><p>MK3S: print everything that says "MK3S"<br/> MK3: print everything else</p> <p>X-Carriages are Optional to give an even better alignment. I would suggest it if you are about to build up a new printer, or about to reassemble the X-Axis anyway. Otherwise in my opinion (and after some tests) it's not worth it rerouting all the cables.</p> <p>special thanks to, gregsaun, JLTX and bastian.s for the great conversation at the PRUSA forum, see the thread here, there you can find some other ideas and designs as well:</p> <p><a href="https://shop.prusa3d.com/forum/how-do-i-print-this-printing-help--f63/any-ideas-how-to-get-this-flexable-material-to-pri-t14765.html#p82986">https://shop.prusa3d.com/forum/how-do-i-print-this-printing-help--f63/any-ideas-how-to-get-this-flexable-material-to-pri-t14765.html#p82986</a></p> <p>some more detailed information about the design and some background information on flexible materials, here:</p> <p> <figure class="media"> <oembed url="https://youtu.be/6z8kk-MUXo0"></oembed> </figure> </p> <p>Supports: none<br/> Resolution: 0,2mm<br/> infill: 25-40%<br/> Material: PET-G</p>
