Thanks for the link to the parallel port monitor that Tweakie sent. I tried it, but it doesn't show that the outputs at my pins are changing. The monitor showed pins 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 13 active regardless of what ever commands I gave Mach3 for movement in the X, Y, and Z axis.
I used a multimeter to check the pins and configured the "motor outputs" for the x axis and made the step pin # 2 and the dir pin # 3. Both were toggled for Active Low.
I used the "Servo Freq. Generator" in the Diagnostics screen and measured the voltage at each pin. Pins 1, 2, and 4 alternated between 0V and 3V every one second, which corresponded to the one second "reversal period" in the servo frequency generator. Pins 8, 9, 10, 11, and 12 responded the same way except they alternated from 1.5V to 4.5V. All other pins measured 0V. I used pin 24 as ground in my measurements. These were all measured off the computers parallel port not the breakout board.
I thought I was onto something and satisfied that I was getting something from the parallel port. However, I'm a little suprised by which pins responded to my x axis "motor output" configuration. I expected pins 2 and 3 to be the only pins with voltages. Is this normal?
If it is normal, then I can narrow down my troubleshooting to the C10 breakout board and not my computer and Mach3.
I don’t have a desktop computer to install Mach3 on.
