Qidi X-Max (X-Plus) Internal Filament Guide v2

prusaprinters

<p><strong>SUMMARY</strong></p><p>This internal filament guide set works with X-Max and probably the X-Plus. It replaces the simple OEM vertical guide with a 4mm ID X 6mm OD PTFE tube that runs from the spool to the extruder. There are four parts: Upper Guide, Lower Guide, Lower Guide Standoff, and PTFE Tube connector for BMG type extruders.</p><p>The setup uses about 1.5 meters of PTFE Teflon tubing 4mm ID X 6mm OD 1.5: <a href="https://www.amazon.com/gp/product/B01CUPV90M/ref=ppx_yo_dt_b_asin_title_o08_s01?ie=UTF8&amp;th=1">https://www.amazon.com/gp/product/B01CUPV90M/ref=ppx_yo_dt_b_asin_title_o08_s01?ie=UTF8&amp;th=1</a></p><p><strong>REQUIRES</strong></p><p>A free spinning internal spool holder such as this one: Qidi X-Max (X-Plus) Internal Spool Holder: <a href="https://www.prusaprinters.org/prints/155518-qidi-x-max-x-plus-internal-spool-holder">https://www.prusaprinters.org/prints/155518-qidi-x-max-x-plus-internal-spool-holder</a></p><p>Because the upper guide occupies the back / left corner, it will interfere with Qidi's carriage cover on the X-Axis. There are a couple of options:</p><ul><li>Adjust the print area: use NotePad or other text editor to create a gcode file with the following then copy it to your USB Flash drive and run it like any other print file.</li></ul><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ; Set XY distance<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; M8024 I270; X<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; M8025 I242; Y</p><ul><li>Or upgrade to the Hercules carriage from Humebeam: <a href="https://www.prusaprinters.org/prints/59209-hercules-qidi-x-max-carriage-for-bmg-dragon-e3d-v6">https://www.prusaprinters.org/prints/59209-hercules-qidi-x-max-carriage-for-bmg-dragon-e3d-v6</a> (I have asked Hume for a mod to the Icarus carriage to provide the same angled cable clip as the Hercules)</li></ul><p><strong>PRINTING</strong></p><ul><li>Resolution: 0.2</li><li>Infill: 20%</li><li>Filament brand: Any</li><li>Filament color: Any</li><li>Filament material: PLA works fine</li><li>Refer to the file notes for supports, adhesion and other guidance</li></ul><p><strong>POST PRINTING</strong></p><p>Use a soldering iron to press in threaded brass inserts to fit M3 hex-head bolts in the upper guide and in the standoff.</p><p>Hold the upper guide on its side and slip it over the Y-Axis drive rod. Then rotate the upper guide into place such that the back of the guide goes behind the Y-Axis drive rod and the top-opening frame slips into the notch. Position the guide fully to the left. Use a 2mm drill to mark the location for a 3.5mm or 4mm hole through which a 3M bolt can pass. Move the guide out of the way to drill the hole. This will allow securing the upper guide to the top-opening frame with a short 3M hex-head bolt.</p><p><img class="image_resized image-style-align-left" style="width:50%;" src="https://media.prusaprinters.org/media/prints/155501/rich_content/dfc1fdcc-d23e-4217-8b7d-c9a8f91173bf/upper-guide-2.jpeg#%7B%22uuid%22%3A%227aeb5852-8374-4787-8be1-62049dd8dfdf%22%2C%22w%22%3A628%2C%22h%22%3A471%7D"></p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Install the standoff reusing the screws from Qidi's guide, then install the lower guide to the standoff with 3M hex-head bolts. There are multiple holes to choose from so that the height can be adjusted as needed.</p><p>Thread 1.5 meters of PTFE Teflon tubing (4mm ID X 6mm OD 1.5). Trim to fit at both ends. A small zip tie to secure the tubing at the upper end of the upper guide may be needed. I used one of the metal grommets that came with the black OEM tubes at the spool end of the PTFE tubing to minimize ware.</p><p>If using the OEM style carriage and cover, then:</p><ul><li>Use this Bowden Tube Connector from Hume Beam: <a href="https://www.prusaprinters.org/prints/82256-qidi-x-max-x-plus-i-mate-s-bowden-tube-connector">https://www.prusaprinters.org/prints/82256-qidi-x-max-x-plus-i-mate-s-bowden-tube-connector</a></li><li>Adjust the print area as noted above.</li></ul>
