The rapid advancement of electronics technology necessitates a modern, safe, and user-friendly approach to printed circuit board (PCB) fabrication. This study aims to develop a prototype PCB milling machine based on an open-source control system utilizing Arduino Uno R3, CNC Shield V3 and GRBL firmware. The system is designed to replace the hazardous chemical etching method with a safer, three-axis milling process. A Waterfall research design model was applied and three main tests were conducted: continuity, voltage supply, and system functionality. Findings demonstrate that the machine performs reliably in terms of power distribution, motor movement, PCB engraving and Bluetooth control. Improvements were made in calibration values and cutting tool selection to ensure optimal engraving quality. The results indicate the effectiveness of this machine in fulfilling the technical and safety requirements of TVET education, while also exposing students to real-world industrial automation systems. Therefore, this machine offers an innovative and low-cost alternative to conventional PCB manufacturing methods in technical education institutions.
