Hi
I was running our old faithfull, 1989 VMC4020 with cnc88 control today, everything was fine, but I hit E-stop instead of feed hold during a program and now the machine REFUSES to raise the Z axis during a tool change. If the program calls for z-moves, it moves no problem, and jogs no problem, but I can't make it change tools anymore! What should I check??
Thanks
John
