    Hi,

    there are a number of motion controller that do the conversion of the USB signals to something to plug in to the break out boards.

    There is a very mixed reaction to using the generic USB to LPT adapters that can be bought in computer shops. I think it may be that they are primarily for printers and not for running CNC machines.

    If you do not have a parallel port on your computer you should consider looking at a PCI card or even better a dedicated motion controller.

    You may be thinking you can do it on the cheap but I found that you spend more time and money trying to make things work if you do not get a good solution.

    Mach3 uses its own drivers for the printer port. The timings are critical and you can't emulate that with a USB -> Parallel converter. It won't work and you will just be wasting time and money.
