I bought a parallel port card from Jameco and put it in the PC. The CD says PCI16C550 (NETMOS)
It installed to windows fine and shows up in the device manager as NETMOS PCI ECP Parallel Port LPT2
It lists the following under resources:
Input/Output Range: A800-A807
Input/Output Range: AC00-AC07
There are no errors showing in device manager.
When I go into Mach3, I checked Port Enabled under Port #2 and entered 'a800' which turns into '0xa800' when I go back and check it.
When I change the step port and dir port to 2 instead of 1 in the Motor Output tab, and move the parallel port cable to the card port, I cant get any movement from the CNC.
I'm using a Rutex R2110 motherboard with R2000 drives, but I am guessing this makes no difference as from what I understand the parallel port is being used output-only for the step and dir.
Anyone have any tips for trying to debug what is going on, or perhaps can recommend somewhere to buy another parallel port card to try?
