Duet 2 wifi homing issue

nicaris

Hi all
Could use some help homing my Ender 5 plus running a Duet 2 wifi .
I completely mashed my config (working on a different printer ) but this had been working fine.
Now I can home X and Y but when I try to home Z the print head moves away form the X endstop .

Links to my Config.g and Homeall :
config.g homeall.g

@nicaris After homing X and Y, your homeall.g tries to move to the bed centre:

; home Z
var xCenter = move.compensation.probeGrid.mins[0] + (move.compensation.probeGrid.maxs[0] - move.compensation.probeGrid.mins[0]) / 2 - sensors.probes[0].offsets[0]
var yCenter = move.compensation.probeGrid.mins[1] + (move.compensation.probeGrid.maxs[1] - move.compensation.probeGrid.mins[1]) / 2 - sensors.probes[0].offsets[1]
G1 X{var.xCenter} Y{var.yCenter} F6000 ; go to bed centre
G30 ; probe the bed

Does it move to the centre?

You have a BLTouch configured. What reading do you see in DWC for 'Z-Probe'? It should be '0'. Does the probe pin deploy? If not see https://docs.duet3d.com/User_manual/Troubleshooting/BLTouch_troubleshooting

Test the direction of movement of the Z axis, see https://docs.duet3d.com/en/How_to_guides/Commissioning#h-10-check-stepper-motors
If you command a positive move of the Z axis, the bed should move away from the nozzle. Does it? If not, change the direction of the motor by changing the S parameter of the M569 command of the corresponding motor(s).

Please post the response to M122, so we can see which firmware version you are using.
