Thermocol / Styrofoam Cutting CNC V3

Thermocol / Styrofoam Cutting CNC Machine V3 | 3D Printed | Arduino Nano + A4988 Stepper Drivers

In this video, I’ll show you how I built a 3D printed CNC machine specifically designed for cutting thermocol (Styrofoam) with precision using a hot wire. The machine is powered by an Arduino Nano and A4988 stepper motor drivers, making it a budget-friendly and beginner-friendly CNC project.
