The Filament Sensor is used to detect the filament feeding status to help prevent print failures and improve overall printing efficiency. 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.
