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.

[Allan Schwartz] decided to document his experience using Fritzing to design, fabricate, and test a custom Arduino shield PCB, and his step-by-step documentation makes the workflow very clear. Anyo… ...
