Project Overview

This project focuses on the design and development of a high-precision CNC machine for drilling and engraving PCB boards. The machine reduces human errors during the manufacturing process and provides a safer alternative to traditional chemical PCB production methods.

The system is controlled using Mach3 software, which allows accurate control of the machine's movement along the X, Y, and Z axes.

In addition, the project includes a web platform where users can download ready PCB designs and upload them directly to the machine through the Mach3 program. The platform also allows users to upload their own designs and communicate with the project team for support or inquiries.
