Problem raith SNF 2011-05-12 18:27:17: Users should call me if they observe any T robot arm position errors

Good Evening
Users should call me if they observe any T robot arm position errors.
I have done what I can to resolve and sometimes it loads just fine but often see software errors and varying end of travel positions.
Likely belt is worn or the coder wheel is lossening up on the axle.
