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.

Components used to build the DIY Arduino CNC machine project include an Arduino Uno development board, CNC stepper shield running GRBL for control, together with NEMA 17 steppers and motor drivers ...

Update: The Cronos grbl board mentioned below gets analysed in this further EinW blog My small cnc mill project needs motors (so I am told) that are too powerful for the normal drivers included on ...

[Reiner Schmidt] was tired of renting an expensive 5-axis CNC head for projects, so he decided to ... His initial version uses an Arduino with stepper drivers, and is designed to fit onto the ...
