CNC Electronics and Wiring

Most of the tutorials on this site are created in response to the difficulties I see users having with machines mechanics, structural dimensions and the electronics that drive their CNC machines. Overwhelmingly, I have noticed the electronics pose the most difficulty with new users. I have put together another set of wiring instructions that demonstrate a methodology that begins with a simple and straightforward wiring of only one driver and motor and follows with the remaining drivers while testing throughout. The steps per inch for many forms of mechanical option are also explained in depth. I thoroughly explain the wiring of the power supply, an optional 5v power supply to provide a 5v digital supply to the parallel breakout board. The wiring of the parallel breakout board from the output terminals to the driver digital pulse (step pulse) and direction lines are explained. The new parallel breakout board appears a bit different, but the process of wiring and testing is the same. Go to the new parallel breakout board to get more information and the wiring diagram.
