The demand for custom-printed circuit boards (PCBs) is rapidly increasing across various industries, including electronics, automotive, and consumer goods. Traditional PCB manufacturing methods involve costly and time-consuming processes, making them unsuitable for small-scale production and prototyping. This paper presents the design and development of a low-cost CNC machine for PCB printing that utilizes a marker pen to draw PCB layouts directly onto copper substrates. By replacing conventional etching techniques, this method significantly reduces the cost and complexity of PCB fabrication while maintaining high precision and efficiency. The CNC machine operates using an Arduino microcontroller to control stepper motors for accurate movement, along with Inkscape for G-code generation. The proposed solution aims to provide a cost-effective, accessible, and efficient alternative for small businesses, engineers, and hobbyists involved in PCB prototyping.
