@nerdyrcdriver I had to turn them up actually to help with the issue. I loosened some of the bolts on rollers and middle to make it move easier as well. All things I should not have to do. I think drivers and motors replaced is an option to look at. They could be permanently damaged at this point. I’m wondering if nema23 steppers and bigger drivers would help. I don’t think there are new style motor mounts for nema23s yet.
At that point I wonder if I should upgrade the belts to chains. Sprockets and idler bearings for #25 bicycle chain is cheap. If it further solidified the machine by eliminating belt backlash that wouldn’t be bad!
