In this video, I build a fully functional multi-color 3D printed pen plotter with an automatic pen changer! No manual pen switching needed — the machine picks pens on its own and draws beautiful artwork.
🔧 Powered by Arduino, stepper motors, and a smart tool holder mechanism. All parts are 3D printed and open-source.
🎨 Features:
Multi-color drawing with automatic pen change
G-code controlled via GRB
Custom pen holder using servo
Compact and fully DIY-friendly design
Whether you're into robotics, 3D printing, or just love CNC art — this project is for you!
💬 Let me know if you want the STL files, firmware setup, or G-code examples.
