I swapped the Z and Y cables and the Z motor behaved the same way. I then returned the old computer and everything worked as it should. So it is not the stepper motors nor the gecko drivers and power supply, thus everything points to the new computer. Curiously, the pin voltages from the old computer do not return to 0 volts when unapplied. The new computer does return the voltage to zero. I would think it would be the other way around. Pin 11 reads a constant 4 volts.
I also swapped pins 2 and 3 with 4 and 5 essentailly changing the control of the Y-Axsi motor to the X-Axis controls and the same problem occured. This narrows it down to pin#11. So I think? unless I'm misunderstanding how Mach3 controls the motors? Could I have a bad pin on my motherboard? It shows a constant 4 volts at pin#11 on both my old and new computers? I get the impression it has something to do with how windows is running Mach3.
If you can make sure I have everything OK in my xml file attached on the original post.
Thanks for your time and input.
