I am looking for a PCI parallel port card card that is known to work with mach 3. I have tried 3 different cards and none of them worked. If somebody could tell me where I could buy one I would really appreciate it. -Adam
P.S. I am looking for one that is as low profile as possible.

I baught my PCI parallel card from CompUSA for I think $15. And it worked fine the first time.
Do you know what brand card it was?
where can I figure out what the address of my port is? I am running windows xp and mach 3
ok, I figured it out last night, i get 5v out of my port now but when the relay for the spindle / coolant turn on those pins drop to 1.4 volts. what's up with that? the relays do activate and hold but why such a drop??
It might be to do with the current being drawn by the relays, you might be better off using your PC's 5volt to power a transistor and let the transistor pull the relay in using a seperate 5volt supply or better still use an opto isolator instead of a relay as they have a lower power consumption.
can you provide a schematic and part numbers? I thought that was the problem but wasn't sure.
I'm at work at the moment, but will look into when I get home, someone else might pop in in the mean time and give you a better solution but I will look it up when I get home and post a reply.
