I posted about this topic last week and I thought my problems were over. I was wrong.
I have done some cuts with my new machine, but it seems that intermittently my Y-axis stepper motors just decide to start moving at different rates. This does not happen in the middle of a GCode file run, but it does happen sometimes when I boot up my board. When inputting 10mm moves it seems that my right y-motor is moving way too much. Here is a video:
I don’t understand the source of the problem, yes, but what is more puzzling is why sometimes this functions fine and other times it does not. The fact that it operates fine sometimes tells me it’s not a wiring issues. Previously I had switched the slots of the stepper drivers and I have checked and double checked all VRef pots. Here is my previous post in case it is of any use:
I would really like to figure this out so I can actually use my machine. Any help is appreciated. Thanks!
