I finally got my PCB mill all wired up and I started with the stepconf

Neither the X axis or the Z axis work. They just shudder. However, the Y axis 
works fine it will do 180 ipm. So I took the stepper off of the X axis to see 
if it would turn by itself and it would not. It just shuddered. So I took the 
motor off the Y axis and put it on the X to see if it would work and no joy. It 
just shuddered. So just to check things out I put the motor from the X axis on 
the Y axis and guess what it worked fine.



Any suggestions in where to go from here?


First thing is to check your wiring. If you have a couple wires crossed up between driver and motor, you would get this kind of issue. Also, if there is a wire that is not making connection at the driver, you could get the same result.
