When I jog the y axis it only moves in one direction. Also, when I am running a program, at any point in the program, it will lose control and the y axis will just move in one direction until it hits the stop (and destroys my part).

I will be stuck for a while and then “out of the blue” it will start working again. The problem will come back when I am cutting a part, (destroying that part)!

And then it all goes away and starts working normal again...

And then it happens again....:tired:


Any one have any suggestions?
