An interesting Arduino project has been published to the Instructables website showing how an Arduino CNC shield and controller has been used to create an awesome 3 axis Arduino CNC plotter.

In that case, grab your Arduino and heat up that etching solution to make your own GRBL compatible shield. This familiar footprint manages to contain everything you need for a three-axis machine.

There is already a CNC project for Arduino called Grbl but [Reza’s] approach uses the Arduino libraries in an effort to make the sketch more customizable for the average user.
