Hi 
i was trying to understand how can i drive my 3 axis steppers via usb??
i mean: as i red mach 3 sends via the parallel port 2 signals (step and dir) the step signal is made of a pulse that becomes high (1) for each step that should be done... and the dir signal made of a constant high(1) or low(0) level depending on the sense the stepper should turn (cw or ccw)..
however what can i use to make the steppers "understand" this signal??
i already heard about the solution of the l298+l297 but i prefer another type of solution
thank you
