I just finished putting together the power supply, setting up the Pro board, and connecting the stepper motors. The problem I am having is that only the X axis moves when being jogged and then it only moves counter clockwise. The Y and Z steppers won't do anything. When I turn on the PS I can feel a thump in each Stepper Motor which I take it as locking up. The Y axis when moving is very smooth. All Steppers feel warm to the touch, but the X and Z steppers have a vibration to them. The Y stepper has no vibration.
The voltage at +5 VDC test Point is 5.03VDC
The current adjustment is set at .4VDC for each axis

I noticed that in the Bios config that the only setting for the LPT1 port is Enabled or Disabled.
Is there any other voltage measurements I can take to trouble shoot why the X and Z axises won't work.
I do design and assemble circuit boards for my company so any help even if a little technical will be greatly appreciated. I am not familiar with this board and don't have any schematics to go by.
I think I will go to www.alldatasheet.com and gather up some of the data sheets of the components on the board.
