<p>Remixed from the optical filament sensor at <a href="https://www.thingiverse.com/thing:1646220">http://www.thingiverse.com/thing:1646220</a> but modified with two M5 holes to allow it to be mounted to a 2020 extrusion.</p> <p>It uses a no-name optical endstop (like this one <a href="http://www.geeetech.com/images/v/Geeetech_IMG_5412.jpg">http://www.geeetech.com/images/v/Geeetech_IMG_5412.jpg</a>) switch and just "guides" the filament threw it.</p> <p>Endstop is connected to a Rasperry Pi running Octoprint, which is handing the correct parking and resuming by using the Filament Sensor Plugin <a href="http://plugins.octoprint.org/plugins/filament_sensor">http://plugins.octoprint.org/plugins/filament_sensor</a> .</p> <p>Works with all 1.75 mm filament (you should be able to drill it up to work with 3mm), except transparent ones.</p> <p>I've also added a version where the holes under the sensor electronics are threaded for M3 screws to hold it in place.</p> <p>I also have one that takes an M6 threaded bowden connector on the output. I recommend printing that at high quality for the threads to work, though.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Folgertech FT-5</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.2</p></div> <p><strong>Infill:</strong></p> <p>20%</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>For the version with the bowden connector, I recommend printing that at high quality for the threads to work.</p></div> </p></p> Category: 3D Printer Accessories
