X axis stepper is skipping! And possibly Y axis as well.
I’ve removed the belts to isolate the issue. In the video you will the x axis stepper skip at certain points… not the acceleration moves but you will actually see it skip. The black marks helps see the movement. The background noise is the y axis and it does something similar but more subtle. There is only one single y axis motor with a torque tube type shaft on each end to turn the belts on the Y.
Any ideas what is causing this, how to confirm and further isolate the issue. Things to try?
