Stepper jitters
« on: July 15, 2013, 07:55:24 PM »
I have had 4 stepper motors running on a Gecko 540  on the bench and all was looking good.Last night my steppers all got he jitters. When i enter a feed comand they just vibrate backwards and fowards a step or so but will not rotate, all four axis are the same.
What have I done wrong or where can I look?

Answered in your other post but will repeat here, it sounds like you have the step and dir pins set wrong, ie you are putting the step out on what should be the dir pin and vice versa.
