CNC Router
Introduction
This CNC Router was designed to shape styrofoam and, or wax, for Casting metal machine parts.
Overview
- Lost Foam casting is by far the easiest type of casting for novist and expert alike
- It was designed to be easily constructed and have up to four axis for complex parts
- Parts can be scavenged from old dot matrix printers and discarded storm windows
- Some parts will have to be bought from hardware stores and electronics supply stores
- It can also considered to be a bootstrap machine that can shape parts to make itself stronger
Electronics
- The stepper motors were removed from three Dot Matrix printers and are "Unipolar" 5 or more wires
- The power supply was removed from common desktop or tower PC 400 Watts is minimum for 3 Axis
- The stepper motor drivers are "Linisteppers" Designed for Unipolar stepper moters and were bought as kits from:

- However they are opensource and can be made at home if you have the skills
- Unless you buy the breakout board advertised for the Linisteppers you will have to build your own and we will supply a schematic we used to build ours.
