Tevo Tarantula filament sensor

thingiverse

This is a custom filament runout sensor designed specifically for the OctoPi case I created earlier. It's incredibly compact and highly adaptable. I've chosen to utilize the Z+ Port, so you'll need to update the FIL_RUNOUT_PIN setting in pins_RAMPS.h to 19: #define FIL_RUNOUT_PIN 19 In Configuration.h, locate the //FILAMENT_RUNOUT_SENSOR define and remove the comment. If you prefer to stick with the default pinout, you should also invert the sensor's logic and disable the internal pull-up: // #define FILAMENT_RUNOUT_PULLUP // Use internal pullup for filament runout pins. and set inverting to true
