Couldn't find a post on this. I just wired up another KL-4030 set of drivers with 35 VDC 10 amp supply and Three 425 oz inch motors. Ok the problem when i flip the switch the motors start moving and jerk a little but never change direction. I thought the motors where suppose to lock up  when power was applied. Any help on this one would be much appreciated.

Thanks

Check your wiring carefully and also check your pin asignment in Mach.
