How to wire Arduino w/GRBL for Parallel Port Control

 

So in this episode we are going to look at wiring the  Arduino running  GRBL to a parallel port CNC machine control yet before you get too concerned this is actually a pretty simple project as what we’re going to cover are the pinouts from the Arduino and matching them up with the opinions of the standard parallel port again most of this is simple soldering to a DB 25 connector which we will plug into the parallel port.
