Voron V2 BTT Smart Filament Sensor Mount

prusaprinters

<p>I recently decided to install a BTT smart filament runout sensor on my Voron V2.4. I side mount my spool holder (front left of the machine) so I wanted a sensor inline with the bowden guide which would be easy to load, easy to access, and which would not interfere with my removable panels. I needed to also adjust the bowden guide as the heights no longer matched and I wasn't happy with mounting the sensor lower as it interfered with the panels.</p><p>&nbsp;</p><p><strong>Hardware Required</strong></p><ul><li>BTT Smart Filament Sensor (remove backplate, reuse screws)</li><li>2x M3 hammerhead nuts</li><li>2x M3 x 8mm socket head screws</li></ul><p>&nbsp;</p><p><strong>Print Settings</strong></p><ul><li>Print parts as oriented</li><li>Supports may be needed on the sensor mount and bowden retainer</li><li>4 walls and 40% infill</li><li>Some filing may be needed on the sensor mount where it snaps into the top extrusion depending on your support/bridging settings</li><li>May need to drill out the bowden guide PTFE path depending on your printer tuning/bridging settings</li></ul><p>&nbsp;</p><p><strong>Assembly</strong></p><ol><li>Remove the backplate from the BTT sensor (save the screws)</li><li>Replace with the printed backplate and attach with the two bottom screws</li><li>Attach the sensor mount to the backplate with the four remaining screws</li><li>Attach bowden guide and sensor to the top extrusion using the M3 bolts and hammerhead nuts</li><li>Feed in bowden through the bowden guide and into the sensor coupler</li><li>Insert a small length of PTFE on the other side of the sensor to guide filament in</li></ol>
