Hi there, I need some help with my parallel port set up. My old desktop doesn't have a parallel port so I bought one PCI-express card. It seems Mach3 won't recognize the parallel port (though I changed the address to 0xCCF0 in mach3). I tested the pins and there are no voltages on pin2 pin3 etc (but there is voltage on pin13 -3.3V). I read one thread somebody posted last year that had the same issue. It mentioned internal parallel port connector. But I can't figure out exactly how it was resolved. Please help!
p.s. I used parallel port tester to check the port. It seems ok. There was a little movement from the motor when I switch from low to high output.
