“In this project, I’d like to share how to build a 2-axis thermocol/ polystyrene cutting CNC machine with its frame and supports made of electrical wire casing/duct and 3D printed parts. Basically it is a thermocol cutting tool which can be used to cut different shapes from the thermocol sheet. It can be used as a craft making tool. The idea of using electrical wire casing / duct as linear rails makes the whole machine affordable and of less weight. With this cutter you can easily cut Thermocol / polystyrene, styrofoam or any other similar material.
This machine is made up of easily available parts like 28byj-48 Stepper motors, Arduino nano, old radio antenna rods, string / thread and 3d printed parts. Hope you like this Idea.
