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.TBL Fixed Console Capture 2-21-22.JPG Hieght Map 2 2-21-22.JPG
Now I am off to the races. I am so glad I bought a Duet.
Thanks for the help Phaedrux.
