Hi, John
Ran your XML, It errors for me like it dose for you.
I think I pined it down to Your Output 1 was set to Port 2 pin 1, I changed it to Port 1 Pin 1, put it back in Exact stop and enabled
Backlash.
The only other item i changed was your X and Y Home pins sharing pin 12 reset X to pin 11.
You need to reload your View screen also.
It works fine hear now, Try the Att. XML.
Hope this get'ssss It, Chip
