Mechanical Filament Runout Sensor for Prusa MK2, MK2S

prusaprinters

<p>New version of the filament sensor from NSGrimace using the snap-on design from CNCKitchen. As optical sensors usually have problems with translucent and transparent filaments, a mechanical microswitch is a good solution to reliably check for the filament.</p> <p>I wanted the sensor to be as small as possible without using screws. I added several improvements to the design:</p> <ul> <li>The housing does not touch the standard idler</li> <li><p>Screwless cover and microswitch mounting<br/> The switch is monitored by Octoprint/OctoPi using the Filament_sensor_reloaded plugin. <a href="https://plugins.octoprint.org/plugins/filament_sensor_reloaded/">https://plugins.octoprint.org/plugins/filament\_sensor\_reloaded/</a></p> <p>Important: The actuation point might differ for different microswitches. You can solve this by moving the mounting rods accordingly.</p> <p>Try it and leave some feedback :-)</p> <p>Happy Printing!</p> </li> </ul> <h3>Print instructions</h3><h3>Category: 3D Printer Accessories Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2DxjZlB">i3 MK2S</a></p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.15 mm</p> <p><strong>Infill:</strong> 16 %</p> <p><strong>Notes:</strong></p> <p>Printed in PETG</p>
