I have tried to post this twice. Maybe the third time...
OK, I'll try to realign the angles. I have been hesitant to try because the angle are 2" x 3" x 3/16" and I don't know if I can get them any straighter (pictures attached). The problem was made worse by the fact that they used top guide bearing and side guide bearings. As a first measure, I have backed off the side guide bearings. They were actually fighting the stepper motors through the arcs. The problem is now much improved. As for realignment, I would need a very accurate 8 ft straight edge, assuming the angles can be flexed into a straight path. Anyway, I will give this challenge further consideration.
Regarding the soft limits, I found the XML file on the drive computer. It is attached to the previous post. Any suggestions would be appreciated.
