DESIGN AND CONSTRUCTION OF A MINI CNC PLOTTER MACHINE

Abstract

A Mini CNC plotter machine is a compact, computer-controlled device designed for precision drawing, and prototyping tasks on various flat surfaces. Utilizing stepper motors and a microcontroller, typically an Arduino, the machine interprets G-code instructions to control the X, Y, and Z axes, enabling accurate two-dimensional or shallow three-dimensional plotting. It commonly employs servo motors or solenoids to handle the pen or tool head for movement and engagement with the work surface. These machines are widely used for educational, DIY, and small-scale design applications due to their affordability, portability, and ease of customization. They are compatible with open-source software like GRBL and Inkscape, allowing users to create vector-based designs easily. Mini CNC plotters support various materials such as paper, cardboard, wood, and plastic, making them ideal for circuit design, label marking, and artistic works. Their simplicity and functionality make them a valuable tool for hobbyists and educators alike.
