Yet Another Filament Sensor for the Ender 2 (4mm Bowden Tube Version) This sensor is pretty simple and reliably detects filament runouts. The sensor can be directly connected to the Ender 2 Board, no additional hardware required. To test the setup I did cut my filament several times and printed multicolor objects for fun. It worked great.
