The drivers are DM542A with a max peak of 4.2A. According to some papers I found online with 1,2,3 off= 4.2A. So I just switched to mach. Can still turn by hand. My enable is not wired at all (just like in the video I shared.) My PUL+(+5v) and DIR+(+5v) are wired to the +5 volt side of my terminal block(as in the video)

When everything is powered on i can feel some pull on the ball screws but i can still turn them by hand. It just feels different when powered on.

Hey TPS, Thanks for sharing that video. The way he wired both pulse- and dir- to ground doesn't make sense to me. I could be wrong though. I basically followed these videos I found. FYI most of the wiring is in the second video but there is some in the first.

OK, I'm back with a 32 bit system. I reloaded Mach 3 along with the parallel port driver. Successfully ran the driver test with a system excellent result. Reinstalled the info for the ports and pins. I still have no axis movement and now the DRO's are showing no movement either. According to what I've read I should have movement at this point. Or am I mistaken?
 So as I'm playing around here I see if I turn the estop port to 0 I show movement on the DRO's when I set that port back to 1 it keeps alarming with external Estop requested?

Darnit  I forgot to check the 32 bit thing and as my luck would have it. Its a 64 bit. I guess I'll be going back to the flea market tomorrow morning.  What did I get myself into. lol

 OK, so I found an old computer this morning at the flea market that's running windows 7. After the Mach 3 install I attempt to run the driver test and I keep getting a window popping up that says: No Driver Sensed Installed. Run Driver Test
Any suggestions?
