This is how I wired mine with the Driver 50 from roy, according to his Uniport manual - http://www.slidesandballscrews.com/pdf/uniport.pdf - it shows it how I was explaining it. But, your driver wiring diagram shows it different.

To be honest i have not had too much experience with the PM542 drivers but looking at the wiring diagram you may be right. Do you have the 270 ohm resistors inline?

What I can not still understand is your output configuration in Mach3, why you are using ouput pins 8 and 9 for the X, 6 and 7 for the Y and 5 and 4 for the Z beats me. Have you tried a different LPT cable?.

So can you summarize what is and what is not working at the moment?

John, have you played with these drivers before?
