I was just running my steppers to make sure they moved good, and I am having a issue with the Z axis. Some times it stopers turning with a awful noise from the stepper. I first thought the lovejoy connectors where turning on the shaft as I have not put flats on the yet, but to find out that is not it. The steppers are just not turning.....like not enough power or something. I slowed it down from 200 t0 5 and it still happens. I have 200 Oz steppers from Hobby CNC. The X & Y where doing it to, but I slowed them down, and it stopped there. Is the 200 Oz just to weak for the Z or do I have something wrong.

HELP!!!!!!!!!!!!
