Unexpected pause for runout filament sensor

  • Hello everyone,
    I'm trying to setup a trianglelab runout filament sensor. This is a normal microswitch with 3 wires and LOW for presence and HIGH for absent.

    So I setup M591 in this way on the config.g (I use E0 endstop)

    M591 D0 P2 C3 S1

    It seems to work perfectly but sometime it goes unexpectedly in pause with runout message.

    I check the wires and endstop state but I don't able to find the solution. Is it necessary to configure other files?
