Great debugging everyone!
I’m feeling that the problem described here is related to
http://forums.maslowcnc.com/t/updated-firmware-with-new-board-has-problems/230
Does that sound right?
I have a fix which I think solves the issue, but I didn’t have a fully test it on Friday so more testing is necessary before we can declare it fixed.
I would love any feedback you can give me on of the fix solves the problem for you.
@blurfl is absolutely right that the issue has to do with the PID tuning so this thread is also relevant:
