My computer that came with my used CNC pooped out and now I'm trying to find a solution to get back up and running. I'm a total noob and I don't know much about computers either, so be nice. I've taken the old Hard drive out of the old PC and connected it to the new PC to run my CAMBAM & MACH3. I also installed a parallel port on the new PC. So far so good - When I run Mach3 it won't control my CNC. How do you know what the port # is? I've tried changing the # on my Mach3 "ports & pins" settings with no luck. What should I try next? OR is there a simple USB option that will save me the hassle of getting a volt meter and hours of testing and resetting port #'s? At this point, I can either call a computer tech or put that money towards a USB-Parallel thing. Please help!!! Thank you!
