      Hi,

      I have some issues since I updated the FW 3.4.4
      RepRapFirmware for Duet 2 Maestro 3.4.4

      I am using Duet IR sensor, and here is my config:

      M558 P1 C"zprobe.in" H2.5 F120 T3000   
      G31 P500 X0 Y0 Z1.70                            
      

      Thanks

        @blacktoli Try inverting the pin :

        M558 P1 C"!zprobe.in" H2.5 F120 T3000   
        

        and try with the help of M119 if the probe works correctly before probing the bed.

          Be careful inverting the pin. If it was functioning correctly before, inverting will either ignore the trigger and crash into the bed, or not move at all because it thinks it's triggered at the start.

          Check your wiring, check the sensor for debris.
