Hi Chip..
Thanks for your help!
Your little printer port tester program is really helping. This is what i found out. 4 pins per axis. Those 8 pins for x,z axis are each reading 3.5v(or very close to that) when turned on at the board input. Axis y pins are only reading 1.7v when on at the board input. Connecting pins 18-25 together. (didn't help).
I've already re-soldered the x-axis printer cable to the y-axis input on the board and it worked correctly., thus eliminating the board as a problem.
Next step is to read the voltage directly from the computer port. If they are good at the port, the cable could be shorting or bad.
What do you think?
