new computer with parrelel port?

[Neale]

Haven't tried it with Mach3 but a PCI parallel port adaptor works fine with LinuxCNC. It's the USB to whatever adaptors that you need to avoid. Only small issue is that the parallel port appears at a non-standard hardware address but the PCI adaptor documentation should provide. It's getting more difficult to find motherboards with built-in parallel ports...

I purchased a PCI and a PCI-E PP cards for my AMD based board and they would not work, strange thing was they only did not work on X axis!

In the end I purchased a Intel based board with the built in port, it has some to do with the voltage the port sends out some ports don't cut it, be warned

Modern PP these days only put out about 3.3V in the older days they put out about 5V Most decent BOBs will level shift the 3.3v to 5V . I don't think there will be any problem using a PCI card with a decent BOB. ..Clive

Did you install the drivers and config it correctly ? there is more than one driver config for Parallel Ports with PCI / PCI-E cards this may help anyone struggling to understand SPP / EPP / ECP HowStuffWorks "How Parallel Ports Work"
