A CNC PCB Milling Setup is a precision machine designed to create Printed Circuit Boards (PCBs) by removing unwanted copper from a copper-clad board. Instead of using chemical etching, this method relies on a computer-controlled milling tool to engrave circuit traces directly, making it an eco-friendly and fast way to prototype electronics.

This setup is ideal for engineering students, electronics hobbyists, and small-scale manufacturers who want in-house PCB prototyping without outsourcing.

Parts Used:

1. CNC Controller Board (Arduino + GRBL or similar)
2. Stepper Motors & Drivers – control X, Y, and Z axis motion
3. Spindle Motor / High-Speed Rotary Tool – performs milling
4. PCB Holding Bed – flat surface to hold PCB firmly
5. Lead Screws / Ball Screws – provide linear motion
6. Linear Bearings & Rails – ensure precise movement
7. Limit Switches – prevent axis over-travel
8. Power Supply – for spindle and motors
9. CNC Software (e.g., FlatCAM, GRBL Controller) – for G-code generation and control
