The F.I.N.D.A probe is the next generation of the P.I.N.D.A sensor with the difference that it works mechanically. The principle of operation is very simple,after inserting filament a small ball of stainless steel is lifted. The probe detects its proximity, which is unambiguous that the filament was loaded. Thanks to the fact that the probe works mechanically it can work with various types of filaments, regardless of the color or material.
Ball is not included
