Automatic Miniature CNC Plotter Machine

The computer numerical control (CNC) machine is in-demand in industries and technical institutions, enabling the control of tools like milling and drilling. The paper aimed to develop a robust and cost-effective mini CNC plotter machine model for PCB prototyping. The user-friendly design of the CNC machine makes the engraving procedure extremely easy. The goal of this work is to create a tiny CNC device that can sketch graphics or pictures on any surface. In this work, A PCB design program creates a layout, followed by creating G-code with axis information translated by the microcontroller's software, ensuring precise mechanical assembly control.
