We've seen one case when a N17/N23 switch caused a motor to make a crackling noise, meaning the switch did not make perfect contact; toggling the switch a few times cleaned it, and the noise was gone.
Thanks for your time also!
I did what you suggested , it still is doing the same thing. No movement in X axis and the Z and Y axis are all studdering back and forth.
