In this post i will present you my first double sided custom pcb made using a simple but “effective” CNC 3020. I’m a CNC newb so my milling process, and the following outline uses what I’ve concluded to be the most common tools. These tools are Eagle CAD, PCB-gcode, Mach 3 CNC, 0.1mm 30deg V-Shaped Engraving Bit, and of course random surplus carbide PCB drill bits from Amazon and several other online markets.
I have to say that this is my first attempt to create a custom pcb so i tried to follow the safest way. (aka large traces width). After designing my circuit using the EAGLE PCB software, i use the pcb-gcode plugin (free) to produce the G-Code for the CNC and using the Mach 3 software i started the milling process.
The following images are the 2 sides of the design and the schematic.
