Thermocol / Styrofoam Cutting CNC V3

How to make Thermocol / Styrofoam Cutting CNC V3 https://youtu.be/-FoAI8sUIp8?feature=shared This project outlines the construction of a DIY CNC hot wire cutter designed to carve intricate shapes and patterns in Thermocol (Styrofoam) using affordable components. The machine uses a 3D-printed frame for structural integrity, modified 28BYJ-48 stepper motors for precise movement, A4988 stepper drivers for motor control, and an Arduino Nano with a CNC Shield V4 for processing G-code commands. The hot wire, powered by a controlled heat source, cuts through the material by melting it along the programmed path. This CNC machine is ideal for hobbyists, model makers, and small-scale prototyping. 1. Arduino Nano: Acts as the brain of the machine, running GRBL firmware to interpret G-code and control stepper motors. 2. 28BYJ-48 Stepper Motors (2 units, modified to bipolar): Low-cost, 5V unipolar stepper motors converted to bipolar for better torque and compatibility with A4988 drivers. 3.
