The Filament Sensor for A1 mini and A1 printers provides accurate detection of filament presence and run-out during 3D printing. When printing with multiple filaments, the filament sensor can recognize the input and output of filaments and transmit the information to the AMS Lite for filament switching. It can also detect filament jamming situations and transmit the information to the printer immediately. This part includes the filament sensor and two BT2-5 Screws.
