I got home and the Y axis wouldn't even jog over and back without error. The Z and X passes the cycle 50 test.

I poked around and noticed that I had knocked the ground off off the motor PS. Hooked it up, all axis passed the cycle50 test.

I did a test cut (air) of the Aztec center test file and for the first time ever everything returned to zero after the job.

Running more test now, but is it really possible that the reload did in fact fixed it and the missin ground caused the confusion?

I for one am hoping so at the moment.

More later.
