Helping my brother - via email - venture into the CNC hobby. He's built a small machine and is now getting his electronics ready to go. His PC didn't have a OEM parallel port so he's ordered a PCI parallel card and will be connecting this to his breakout board.
Are there any caveats to be aware of when configuring Mach3 with add-on cards? I use an older PC that had its own parallel port so getting Mach3 going was a snap, so I have no experience with his setup.
Just trying to head off any potential problems in order to get him up and running with minimal fuss...
Thanks!
