      Hi all,

      OK, so probing and all is working 100%, but the compensation is in the wrong direction.

      In the documentation it states "Note: If you are experiencing the Z axis compensating in the opposite direction needed, that means your Z motors are swapped. You can either swap the X values in the M671 command, or swap the stepper motors plugged into the Duet."

      I do not understand what I need to swap?

      Here the info:

      ver
      Board: Duet 2 WiFi (2WiFi)
      Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.3beta2 (2021-03-10)
      Duet WiFi Server Version: 1.23

      config file
      M671 X0:0:324 Y74:324:199 S10 ; X0:0:324 Y74:324:199

      bed.g file
      M561 ; clear any bed transform
      G29 S2; Clear bed height map
      ; Probe 3-point
      M401 ; Deploy probe - deployprobe.g
      G30 P0 X0 Y30.7 Z-9999 ; Front Left
      G30 P1 X0 Y280.7 Z-9999 ; Back Left
      G30 P2 X324 Y155.7 Z-9999 S3 ; Center Right
      M402 ; Retract Probe - retractprobe.g

      And yes, two z leadscrew on left of bed; one on right of bed in middle, hence
      0,74 & 0,324 & 324,199 (xy coordinates)

      Any help/suggestions appreciated!

      Tinus

        M584, M671 and the probe points have to be in the same order
        you can't have
        M584 left:right:back
        M671 right:left:back etc
        They must be
        M584 left:right:back
        M671 left:right:back

        G30 P0 Left
        G30 P1 right
        G30 P2 back

        edit: removed the G30 probe order being important after dc42's comment

          Actually the order of the G30 probe points doesn't matter.
