DIY Filament Runout Sensor
thingiverse
A basic filament runout sensor. Required Parts: - Kw10 z5p Micro Switch (Or another switch of the same size) - x3 M3x10mm Bolts and Nuts - x2 M2x10mm Bolts and Nuts - x2 Teflon Tube (about 20mm) (optional) Connection: You can use this sensor on any printer. Connect one of the pins of the switch to the data and the other to the GND pin. Thats it. *I recommend using the C and NC pin of the micro switch. Firmware Configuration: - Find //#define FILAMENT_RUNOUT_SENSOR and remove the slashes (//) - Make sure the lines below are the same for you; #define FIL_RUNOUT_ENABLED_DEFAULT true #define NUM_RUNOUT_SENSORS 1 #define FIL_RUNOUT_STATE LOW #define FIL_RUNOUT_PULLUP This configuration worked fine on my ender 3 pro printer with SKR mini e3 v2 motherboard. It will probably work for you too.
