Hi,
you will need an external motion controller to use that PC. You CANNOT USE ANY 64BIT OS
to run Machs parallel port, you MUST use an external motion controller.
If yo really want to use Machs parallel port because its free then you need a PC with Windows7 or earlier,
32 bit only.
A UC100 (not a Chinese rip-off copy) or a 57CNCdb25 are both USB connected whereas the more
capable Ethernet SmoothStepper, 57CNC, and UC300 are all Ethernet connected.
