Hi; I have built mini CNC plotter using some old DVD drives the inspiration for which came from this video. The build uses an Arduino Nano and two L293D motor driver IC's (Not boards). The video included links to a couple of gcode images and an Arduino Sketch which appears to listen for serial data (the gcode file) and activate the stepper motors and servo to perform the drawing of the image.
