hello everyone. i apologize in advance if this is in the wrong forum but i was unsure where to place it. i am an electrical engineer. ive never built a cnc before and this is my first try at it. i have no problem to build the hardware (eletromechanical or circuit boards) but my laptop does not have a parallel port. i want to use a usb port instead. i can easily design a conversion from usb to parallel or serial on the pcb but i am unsure how to go about this with computer. i was looking at mach3 software and the manual goes into parallel ports and how it uses them. it states that i cannot use a usb to parallel conversion cable. is there a way i can have like a "virtual parallel port" through software that the mach3 application could communicate to and i would build the usb to parallel conversion myself on the stepper driver side?
thank you in advance.
