I can upload and give as much information as possible able my software and driver and the machine. I answered all the troubleshooting quesions at the beginning of this thread. But I do not believe that this is related to the electronics. I have cut these same circles on this same machine without this issue. I had Jitter problem so you recommended resquaring the middle and tighten the rollers. That is all that has changed for these results to change. My thoughts were that maybe there is still a problem with the middle assembly or too much belt tension on one axis causing missed steps. Thanks for all the help.
