Now each time you click the yellow arrows (up and down for the Y axis) the computor will output one pulse to the stepper motor driver circuit. I am from India and most of the off-the-shelf drives as well as Drive Kits mentioned in most of the posts are from the US...but for a Hobby CNC Enthusiast like I have the pm55l-048 motor to test with. So for a 3 axis machine we really only need 6 pins in out parallel port.
