Now, by using the cursor left/right and verifying the change in the "X Pos" on the diagnostic screen, I can toggle the state of the pin 13 LED. This verifies that the Mach3 X-Axis Direction output can be set correctly by Mach3. Note, I'm ignoring the X-Step signal because this is a very short duration pulse that won't be shown on the LED status on the diagnostic page.

Ignoring the Step signal - which is critical to this, but noting the difficulty in measuring it. If the X-DIR signal and X-Step signal work then the X-Axis of the machine when plugged in should work and should be under user control with the Cursor Keys. If not, then we move to the Syil.
