optical light barrier as filament sensor invert
-
I built an optical light barrier as a filament sensor (see screenshot). The filament sensor also reacts when I put the filament in. But I want the error message with pause when the filament is missing, so the barrier is not interrupted. Nothing has changed about S1 and S2...is there another option?

@axiom have you tried inverting the pin logic by putting an ! mark in front of the pin name in the M591 command:
