Make a mini CNC drawing machine

Make a mini CNC drawing machine

Arduino TeamJanuary 21st, 2019

For an easy plotter design that you can build with only simple hand tools, be sure to check out this tiny project from Mr Innovative. The machine features a pair of stepper and lead screw assemblies to maneuver a pen in an X/Y plane, along with a clever string and servo setup to handle retraction.

An Arduino Nano and two L293D ICs mounted to a custom PCB are used to control the device, though a breadboard could certainly substitute for the PCB in a pinch. Drawings are translated into the proper format via Inkscape and Processing. 

More details on the miniature machine, including code, can be found in Mr Innovative’s write-up.
