I've had things like this happen before. Try reinstalling Mach3 and the Plug-in with a fresh install ie: Delete the old first and Don't install the parallel port driver when installing mach3.

If still does it then I'd say yes could possibly be faulty but I'd be very surprised. I've fitted Dozens now and never had a faulty unit, I've killed a couple but that was my fault.!
