CNC Hot Wire Cutter for RC Airplane Wings
Arduino Blog
EDITOR BRIEF
A custom CNC hot wire cutter was built to make lightweight foam wings for RC airplanes. It uses a heated nichrome wire moved on four axes so it can cut straight or more complex wing shapes, and it runs on parts similar to a 3D printer with G-code from an online wing-design tool.
INSIGHTS
This is a good example of combining mechanics, electronics, and software to solve a practical build problem. If you’re learning, try mapping how G-code and stepper motors control motion in a machine like this.
