What does it mean when the arrow jog keys stop functioning properly?
Specifically, the X is fine, but the Y axis, both arrows, up and down, move the gantry the same direction. This happened out of the blue. I cant see anything overtly wrong with the leads. Here's something though, just after I turn the controller on, I can get it to move correctly over a period of about 10 seconds, then it's back to both arrows moving the Y the same direction. Also, Ref all home has the same effect, it tries to home, but the Y is moving in the wrong direction.
Now, the stepper sounds like its having a rough go of it, as well. What should I dissect first?
Thanks Guys,
Eric
