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.

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.

“The pen plotter in question is a DIY machine that Oaks constructed using linear rails, stepper motors, and an Arduino Uno board with a CNC Shield that runs Grbl firmware. The computer connected ...
