<p>This is a simple filament guide to use a cheap LM393 sensor as filament sensor.</p> <p>It is inspired in the filament sensor of Prusa i3 mk3, but simplifying the requirements and the cost.</p> <p>BOM:</p> <ul> <li>1 x ball of 3.85mm. You can get this disassembling a 608z bearing.</li> <li>1 x magnet 6x10x2</li> </ul> <p>Build:</p> <p>Just print the piece, put the magnet before put the bearing, and insert the piece between the sensor.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Prusa Bear Custom</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>0.1</p></div> <p><strong>Infill:</strong></p> <p>20</p> <p><strong>Filament:</strong></p> PaL PLA <p>Gray Post-Printing =============</p> <p><strong>Concepto</strong></p> <div><p>This adapter looks incomplete and maybe it is, but the idea is that you adapt this into what ever, in my case I am using this into a bondtech extruder:</p></div> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/87/76/7f/1d/87/WhatsApp_Image_2021-05-25_at_19.40.51.jpeg"/></p> </p></p> Category: 3D Printer Parts
