It uses inexpensive 3d printer electronics and parts easily found in your local DIY store.

I use it to make RC wings and fuselages but it can be used to make many other foam projects.

Part 1 is the introduction give a brief overview of this step by step series to build your own CNC foam cutter

Part 2 Updated (Oct 2020) is the electronics build and configuration, this video including calibration and end-stop

Part 3 is the mechanical build.

Part 4 is the video showing wiring, axis checks, calibration checks(use this video for calibration) and making our first test cut. The last section shows software you can use to generate G-code for your wing

The free eBook also includes detail on how to build the parallel port version, if you want to use Mach3 or Linux CNC
