@alex-cr et all...

FYI to close the loop for those who have offered help: I contacted Filastruder - they sent me a replacement LDO motor for the Orbiter v1.5. I got to play with it a bit this evening and bench test it - it is working perfectly. Now I can complete the upgrade and actually test it using some plastic.

I also purchased the Duex 5 add-on board so I can replace the burnt driver and add some additional drivers so I can now implement a three stepper Z axis.

Thanks again for your help - Mike

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.
