@mikeatfhc you may be probing too fast for the Z motor to stop instantly when the probe triggers.

@dc42 I've tried slowing down my probing to F20 but I am still getting a very out of level bed.
Here is my Endstop section of my config.g - any other pointers?

Often times the reason for auto leveling to produce bazarre results is that the order of the points for the steppers defined in M671 doesn't match the order of the drivers defined for Z in M584. this causes the firmware to move the wrong steppers than expected.
https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling
You must use the M671 command to define the X and Y coordinates of the leadscrews. The M671 command must come after the M584 command and must specify the same number of X and Y coordinates as the number of motors assigned to the Z axis in the M584 command; and these coordinates must be in the same order as the driver numbers of the associated motors in the M584 command. The M671 command must also come after any M667 or M669 command.
So take a look at that and confirm.
M584 X0 Y1 Z2:5:6 E4M671 X-45:170:342 Y35:250:35 S10Another way to test is to manually level the bed so that it's starting with a very flat plane. Then run your bed.g and see if it makes any adjustments. Run bed.g a few more times and see if the adjustments are getting worse with each run. That indicates it's not adjusting the right motor.
-
It took a couple of reads for me to grasp what you were saying here, but after the lightbulb went off - it was obvious that the firmware didn't know which lead screw to adjust if they were not in the expected order in M584.
Checked my wiring... sure enough the wires to the stepper drivers were out of order - I needed 2:5:6. Swapped the wires, problem solved immediately.
I ran the G32 routine a few times and the differences in height became smaller indicating its working perfectly now. I re-ran my Mesh and got this height map and these results from G32 in my console.
Now I am off to the races. I am so glad I bought a Duet.
Thanks for the help Phaedrux.
