OK,
I think I figured it out. After doing a "REF ALL", if I hit shift to rapid jog the X axis, the dro was way off.
I tried this a couple times. Then I did it all over again in slow jog, was ok. So I dropped my X velocity from 157 ipm to 150ipm.
Accel is 13.6. That seemed to fix it.
I'm also enclosing my xml, in case anyone wants to check it.
Thanks
Ed
