Thanks, I have mostly sorted this out. The PO upgraded to MK2.5, when I figured that out I loaded correct firmware and it now breezes through the XYZ calibration.

I did not read the 70 pages in this thread. I recently purchased two used Prusa i3's a MK2 and an MK2 upgraded to MK2.5S The upgraded one does not work and I'm looking for a forum where I can get info on how to fix it. I'm new to 3D printing but I'm an engineer so pretty good at fixing things...
