For the filament sensor the pressed switch is the CONTINUE/RUN condition, while a non-pressed switch is the ERROR/STOP.
For endstops this is reversed. A pressed switch is the ERROR/STOP condition, while a non-pressed switch is the CONTINUE/RUN condition.
A closed loop should be correct condition - filament present (and no brokens wires).
The error condition - filament missing (or broken wire) will be the open loop.
The button is pressed (to the non-normal-position) when there is filament.
Thus one should use Normally Open for the filament sensor.
