So I er... found the problem...
My PSU did not have enough muscle to push the motors. I have a "Logic Power state" led in the circuit that shows when theres power on the IC's. My test equipment (a row of LEDs) used for marking the sequence from the motor out connections obviously requires WAY less power than the actual steppers.

I found that by ripping two old computer PSU's and bridging them for 24V worked a chink! Sweet actions left and right. I wonder if the pulsing had something to do with this issue since the other software packages work just fine. Anywayz, after some time on the motor tuning screen I FINALLY got my rig to move.

Thanks for ALL your help Hood. BTW I downloaded a layout screen I think you made from the Mach website, cool stuff man!

Ok, I took some readings, this is what I found:

Dir pin switches between 0.06 - 3.31 volts.
Step pin is very low at 0.05 - 0.17 volts during normal motor tune. If I set the velocity at maximum and accel at minimum I get a reading of 1.05 volts for the step pin.

I'm using the Tach42 board from the PMinMO site.

Could there be a problem with the mode my Port is set to? I think at the moment is is set to Bi-directional. Is that ok?

Ok, the Outputs are not connected to anything but I tried to enable them to see if it could make stuff move. I've reinstalled the program but still nothing. I set the Step pulse speed at 5 and Dir at 5. BTW, all outputs are now set to be disabled but when I "run" a program output1 flashes in the Diagnostics view. None of the pins show activity in this view either.

I'll post another xml of my configs.

thanks for all the help so far!

Everything I think I need right is right. The board I'm using is the Tach42 from PMinMO so the pins are per that design. I have resorted to measure the voltage off the pins during operation but NO change. Interestingly enuf, if I enable the "Low active" triggers next to the motor pin setups I get a voltage reading but my step pins aren't pulsing.
 Here is the xml anyway as you requested Hood.

Well, yes many times. By installing "drivers" I assume allowing the entire setup program to run it's course? I had a look at my hardware config and noticed that I now have a "Mach pulser" installed. I cant config any setting on it.

I had a go with Quantum on my laptop but the same issue persists, no movement.

Help Help!

I installd Mach 3 and done the port setups as required by my stepper driver but no joy! What am I missing? TurboCNC and KCam both get my machine runnig but Mach3 doesnt do a thing, not even some jitter.

Everything is powerd up well but it's like there's a settirng I cant get to. It also appears that the LPT port is passive or "off" under Mach. Any ideas or suggestions?

I run XP with SP3 @2000MHz with 512Ram
