QIDI X-MAX Carriage upgrade

prusaprinters

<h5><strong>IMPORTANT: </strong>This design is based on <a href="https://www.printables.com/model/59209-hercules-qidi-x-max-carriage-for-bmg-dragon-e3d-v6">Hercules - QIDI X-Max Carriage</a> done by member <a href="https://www.printables.com/social/48305-humebeam/about">humebeam</a>. Not sure if this counts as an actual remix since most of the original design has changed and the complete carriage remodeled. <i>All the firmware instructions from above mentioned link still apply, while the BOM has changed slightly.</i></h5><p>&nbsp;</p><p>First thing i wanted to tackle is the printability. While i do not have anything against printing with supports, i tend to avoid them whenever possible. This meant some parts have to be printed as separate objects, this is actually a good thing as well as you can simply replace parts of the carriage without the need to reprint the whole thing, like ribbon cable anchor/holder, cooling funnel etc…</p><p>Next thing was to change the mount for the Dragon hotend. To do this, i have re-modeled the BMG extruder back plate so the Dragon screws on to it directly, no more twisting and turning of the hotend when changing the nozzle. This part is printed and fits the original (or Triangelab) BMG extruder.</p><p>&nbsp;</p><h5><strong>Features:</strong></h5><ul><li>ALL parts printed without any supports</li><li>Modular design means parts can be changed/added/removed without re-printing the whole thing</li><li>Strong mount for the Dragon hotend - one hand nozzle change</li><li>Greatly improved hotend cooling thanks to the turbine air funnel. This prevents air back pressure and allows use of silent fans without fear of clogging the hotend.</li><li>Zip tie holes for securing all cables</li><li>Inductive probe mount - suitable for OMRON, Panasonic or P.I.N.D.A. probes</li><li>Greatly improved part cooling thanks to advanced fluid simulations done on the part cooling duct.</li><li>ADXL345 mounting point for Adafruit ADXL345 - Automatic Input Shaper tuning with Klipper conversion</li></ul><p>&nbsp;</p><h5>BOM:</h5><p>This is basically the same as from the HumeBeam's article. I like to use high quality parts like BMG/Slice Engineering/Phaetus… but Triangelab is the next best thing and perfectly suitable.&nbsp;</p><figure class="table" style="width:100%;"><table><thead><tr><th>Part</th><th>No.</th><th>Link</th></tr></thead><tbody><tr><td>BMG Extruder</td><td>1</td><td><a href="https://www.3djake.at/bondtech/extruder-bmg-rechts?sai=3001">3DJake</a></td></tr><tr><td>Phaetus Dragon Hotend (Triangelab OK) Both SF and HF are ok!</td><td>1</td><td>&nbsp;</td></tr><tr><td>T-K500 Thermocouple (3 x 15 mm)</td><td>1</td><td>&nbsp;</td></tr><tr><td>40x10 or 40x20 Fan for hotend cooling, pretty much any will do.</td><td>1</td><td>&nbsp;</td></tr><tr><td>M3 brass heatset inserts</td><td>14</td><td>&nbsp;</td></tr><tr><td>Nema17 pancake stepper</td><td>1</td><td>&nbsp;</td></tr><tr><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td></tr></tbody></table></figure><p>&nbsp;</p><h5><strong>Printing:</strong></h5><ul><li>Material: <strong>PC or PCCF is highly recommended</strong> due to very high temperature resistance.
