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.

“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 ...

All of the hardware, except for the camera, is controlled by an Arduino Giga using a CNC shield; the camera is directly under the control of a host computer.

UPDATE: The FR4 Machine Shield is now on Kickstarter We know the concept from quadcopters, little robots, and generally things that are small enough to make use of their PCBs as a structural ...
