      Hi,
      I have a small stepper motor, and for systemic reasons it has no end stop. This is fine and not problematic.
      At the beginning of the run I would like to do homing to its current location as it is. (To set the existing position as 0 and in addition to lock the motor that will not move easily)
      For the first part I use the command G92 U0 - it performs homing from the duet, the position is set to 0 but for some reason the stepper is not locked. What am I missing to make sure the homing locks the stepper?
      Additionally, I removed the M84 command from the configuration file

      Thanks,
      Adi

        @adistr use command M17 U to energise the stepper motor. M17 is supported in firmware 3.3 and later.
