Filament sensor F.I.N.D.A. - this sensor is in fact a PINDA sensor with MK2 / S without a thermistor. It is used as a filament sensor triggered by a steel ball. The material for 3D printing passes through the selector, lifts the steel ball towards the sensor, while in the upper part of FINDY there is an LED that turns off as soon as the filament is detected. When the filament is pulled out, the ball drops and the LED lights up red.
