Mechanical Filament Runout Sensor for Prusa i3 MK2s
thingiverse
I wanted the runout sensor as close to the extruder as possible since I'm using an enclosure. It was never an option to have it outside the enclosure. The printed part is attached using spare zip ties from assembly. A short one attaches it to the Pulley Idle and a long one closes the "box" and keeps the sensor in place. This setup is designed for use with the black mechanical endstop that I used, available at https://www.aliexpress.com/item/5pcs-High-Quality-Black-Mechanical-Endstop-without-the-wheel-For-Reprap-ramps-1-4-3D-printer/32652391956.html?spm=2114.13010608.0.0.Df5CY3. The sensor is connected to my Raspberry Pi 3B running OctoPrint. The Enclosure Plugin in OctoPrint sends the command "M600;" once the sensor is triggered, which moves the printhead, sounds a notification, and starts the filament-change command on the Original Prusa i3 MK2s. The wires are connected to pin 4, 6, and 8 for my specific setup with a Raspberry Pi 3B and this type of sensor.
