SunRobotics PORT BUFFERED BREAKOUT BOARD FOR 3 AXIS CNC MACH3 Micro Controller Board Electronic Hobby Kit

Mach3 CNC Stepping Motor Driver Interface Adapter Breakout Board +USB Cable. Parallel Port Breakout Board is a low cost complete solution for small cnc machines like CNC routers and can be controlled directly from PC parallel port. This board can be used to control CNC machines which use 3 Stepper or Servo motors. The drives for steppers or servos must have impulse (step & direction) input. Only 3 connections are required for each drive – Step, Direction and GND. If PC is not having parallel port an add-on Parallel Port PCI card can be added to get one. You can also add multiple cards and breakout board to create more complex system with many IO pins.:
