Have a B0326-II that has some issues. Main side seems fine, sub side is a pain. When I set a part up, and run it to only run one part, all is fine. But, when I run it in continuous cycle, diameters on X axis(sub side) change by about +.003, just on the first operation, and hold there. Touch off on Z axis at zero, and have to make a +.015 offset to achieve my OAL. Doing any kind of break/radius during the first op, I have to really alter programming in order to achieve what I need, a .01 45 deg. looks like a backwards radius. I have checked ball screws, no backlash. Believe it to be electrical. Any ideas/suggestions are appreciated.
