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.

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 ...

The ‘under’ in Undershield comes from this shield being mounted underneath the Arduino, unlike every other shield on the planet.

Making an Arduino-based CNC plotter out of a DVD player is as easy as 1, 2, what’s Arduino again?

OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus demonstration software.
