Overview
Prototyping a circuit board in this way is a good idea so you can be sure that things are working before sending your PCB off to a fabricator. This method is also a good way to do low run or one off testing PCBs.
G-Code is made up of some simple commands that tell a CNC mill how to move so that your designs come out correctly. This is also called a Tool Path. PCB-GCode is an add-on for EAGLE that lets you create a Tool Path in G-Code so that it can be made by a CNC Mill like my Shapeoko 2. Though there are many ways to create G-Code for PCBs, I will focus on EAGLE and PCB-GCode because they are rather easy to use and the software is free for making basic PCBs Continue reading Create G-Code from an EAGLE File
