The pin just stays at 5V all the time, even when I try jogging. Makes me wonder if the parallel card is bad. I did find other posts where people used this one successfully, but it is an old card. Or could I have an incorrect setting in the 'Port Settings' for the parallel port? Right now I have these defaults:
- Filter Resources Method = "Never us an interrupt" (other choices are "Try not to use an interrupt" or "Use any interrupt assigned to the port"
- Enable Legacy Plug and Play detection is disabled
- LPT Port Number is LPT1 (Although I don't think this matter as long as I use the correct port address in Mach, which I'm pretty sure I have correct, because definitely has some connectivity.)
Thoughts? Try a different parallel card?
