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.

So we’ve been doing a lot of experimentation in the lab lately with motion control and one of the latest projects we’ve been working on is converting our Probotix Fireball V 90 from parallel port control using Mach 3 to using GRBL on the Arduino as a replacement. The reason for this is we want to take advantage of the many second-generation programs out there such as Easel and others which streamline the workflow of the CNC process. However one of the first challenges is getting GRBL on your Arduino itself and to do this we took a quick scan of the Internet and couldn’t find any good videos demonstrating how this process works, so the next step was to create one of our own and in this video we will show you how to flash the Arduino and send commands to GRBL and more importantly where to find all this in addition below we have placed the key URL links to what you will see in the video there so they are easy to find.
