SOLVED!!!!! 

the whole problem was from the fact that the onboard parallel port was 3.3v.  I spent so much time assuming that i had a signal, that i didn't check to see what the actual voltage was.  now it works exactly as it was supposed to!!

for those who run across this thread or have this same problem, i ordered this parallel port from newegg.com for around $14 with free shipping (which is why this post is 10 days later.  shouldn't have cheaped out and paid to get it sooner!)

Hey Tweakie!

I solved my Laser issue! I dumped the Blue board and went with break out board & 2 driver boards for X & Y. I forced myself to read the MACH 3 manual  ::). I ran the Z DIR pin into the Relay on the Break Out Board. I then ran the Output of the Relay to the "L" on my PSU. I turned on the Spindle Control on MACH 3. No Ground wire needed. IT WORKED! This is not exactly what I wanted it to do "REALLY :o?!?" I wanted it to be variable controlled but I will take this win anytime!! I will figure that out later.


Thanks Tweakie for your help

Jeff

Glad to see you got yours working! Are you able to vary the Laser Power Output "Variable" or is it ON - OFF like mine now? I want it to be variable power.
Going to order one myself, we both had the exact same issue. Could you post screen shots of you MACH 3 setup for this Laser?


Thanks in Advance
Jeff
