Hi all:
I am upgrading a small cnc to a more powerful cnc and am using mach-3.
what I need to know is how to interface the PWM signal from mach-3 to
drive my 12 volt DC motor. You can't just connect the output of the
parallrl port to a mosfet driver, can you??? what kind of circuit do i
need? Anyone?

thanks:
Bill
