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.

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.

Making an Arduino shield can be simpler than you think. This time I designed one to program Attiny and Atmega ...
