Additionally, because the UC100 offloads the time-critical bits, it allows Mach3 to run on versions of Windows which do not use the PP.
Yes, I understand that part of the information and fully support using the UC100 and would bin the one I have that the previous owner purchase. That I fully understand but what I cant get is I said earlier that rather than spending money on the PP to USB convertor why don't I put that money towards another BOB or external unit that is either flashed or direct USB controlled

"I can not do away with the conversion process, you will always need a motion controller" Indicating that I would always need the UC100. This is the bit I don't understand.
