Abstract

This project aims to develop a low-cost CNC Router targeted at small entrepreneurs, technical students, and maker community enthusiasts. The motivation lies in the lack of accessible digital manufacturing solutions that combine precision, reproducibility, and affordability. The methodology involved research, reuse of components, electromechanical assembly, and Arduino Uno programming, using the GRBL firmware and Universal G-code Sender software. The tests demonstrated that the machine achieves adequate precision for applications in wood, plastic, and printed circuit boards (PCBs), confirming its functionality and replicability. The results highlight its educational and productive potential, representing a viable alternative to reduce technological exclusion in low-resource communities.
