Hello All,
An issue is back with Y axis motor outputs. I had grinding issues in the past and it was cable related and may have been the issue I have now all along. These are the Nema 23 motors. At mid to low feed rate speeds I am getting some “audible jitter” in motor movement. It is not affecting carves whatsoever, but its irritating and feels wrong for lack of a better word. This is my second controller and complete 2nd cable set. I have replaced cables with no change. What I have found is that if I swap the Y and Y slave motor cables at the controller itself, the problem follows the controller output (m2), not the cable. Mechanically both rails are smooth as silk, just never at the same time; only when cabled to m1. I really don’t want to buy another controller and am looking for any suggestions, even if component level or a good price on a used controller. My intent is to elite upgrade at some point, but not in an effort to fix this issue and pass the problem on to someone else. Any help appreciated.
Thanks-
