Hi Chip
Yes the Z motor moves without any commands, its shaft twitches every +- 15 - 20 seconds.I have the motors sitting on my bench, first want to make sure I can solve this problem before installing them on my machine.I have played around with the Step/Dir pulse settings but to no avail.I am running a HobbyCNC 3 axis pro board with HobbyCNC 305oz/in stepper motors.I have ticked low actives on for Dir/Step, all the pins are set correctly, all the axis move when commanded its just the Z motor twitches on its on.If I disconnect the parallel port cable everything is fine so it cannot be my driver board.Thanks for the Advice
