Filament Runout Switch Mount

prusaprinters

<p>I have made so many things from Holspeed's filament roller, thanks for that! This is just another place to put a microswitch on your Ender 3. I wanted to give it a straight path with enough clearance to get my fat fingers in there to feed filament.</p> <p>Credits also to eussrh for the switch holder! I did square off the discharge end to accomodate for the reed. I also put a slight bend in the reed at the exit end of the enclosure.</p> <p>For this, I used a Philmore part number 30-18222 and three 2mm x 16mm screws and nuts for the switch and a 608 bearing and a 3mm x 20mm screw and nut for the roller.</p> <p>You will need two spacers for the inner bearing race.</p> <p>I used the ZMax, which is the D19 highlighted in the pinout diagram for the MKS Gen L. Marlin defaults to Servo_3, but even when using the pull up resistor I was getting an intermittent, but that might just be my board.</p> <p>I tested this repeatedly using both Pronterface and live testing.</p> <p>I know there are many different styles of these floating around, but I mashed this together to fit my requirements. Maybe someone else will get some benefits from it as well.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.12</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> any PLA any</p> </p></p></p> Category: 3D Printer Parts
