Arrg!! My machine is working well, but has the repeatability of a blind squirrel. I can't run more than 40-50 lines of code before an axis will fault for some reason. I can't seem to find any possible explanation for this. I don't know if this is the servos stalling or what.

I am running G320's with 1000 PPR Renco differential encoders and Electrocraft 60v servos. I am a little unsure here. I called Mariss and he said a diff. encoder could be used as a TTL so long as only channels A and B were connected. He also said I could use 10 ft cables no problem as the geckos can filter noise, but at 45,000 Hz isn't it more than likely that the servos will fall 128 counts behind?

The only other cause that I can come up with is my ballscrews are too tight and I am stalling the servos. I set about 100 lbs of preload so it takes a fair amount of force to turn them over, but I can still do it by hand so a 720 oz-in should have no problems right? The machine snapped one of my cutters like a twig today so I am also skeptical about this cause. Please help.
