Did it all day again today.
The A would lock up, I'd swap X and A, and they would both work.
At the end of the day A locked up again, I swapped cables and it followed the cables (X was now locked and A moved).
Checked all the connections. It seems early today it was locked and after I checked and tightened everything in the back of the computer it worked...but I don't know if it's related
I was able to cut parts intermittently. I cut small ones and baby-sat until it happened again.
My thought is it's whatever drives the A axis
but don't know.
