Hi, I have Mach 3 running a cnc router, I have used it successfully several times, but if it is left for a week or two, on startup I can't get the Z motor to run, it will make sounds like it is running and sometimes will jump when I jog it, in the past it has seemed to cure itself but not today, I played with motor settings in all combos, nothing seems to help. Any body run into this problem?
Thanks
Terry
