Design And Construction Of A Mini CNC Plotter Machine

Abstract

The Mini CNC Plotter Machine is a compact, computer-controlled device designed for precise drawing and engraving applications. It operates using stepper motors controlled by an Arduino board, typically interfaced with GRBL firmware and G-code commands. The system translates digital vector designs into accurate physical outputs on paper or light materials such as cardboard and acrylic. Equipped with an X-Y-Z axis mechanism, the plotter ensures smooth and coordinated movements, enabling high-resolution sketches and text rendering. A pen or engraving tool serves as the output medium, mounted on a movable platform. The machine is often built using recycled components like DVD drives, making it cost-effective and environmentally friendly. Ideal for educational, prototyping, and small scale design tasks, the Mini CNC Plotter offers hands-on experience in automation, robotics, and computer-aided design (CAD/CAM). Its simple construction and affordability make it an excellent project for students and hobbyists interested in CNC technology and digital fabrication.
