Filament sensor for 3D printer

Feltsensor used in RepRap 3D printers. It is connected to the main board of the device. Main task of the sensor is current control of feeding material for printing. If its travel is correct, the LED located on the sensor lights up green. In case of sudden interruption due to depletion of the filament, printing is stopped. This is indicated by the green LED going out. Stopping the work allows you to avoid damage to the model being formed. After replacing the printing material, the device resumes operation. The sensor is compatible with 1.75 mm diameter filament. The kit includes a connecting cable.
