This is a compact CoreXY CNC machine for PCB making at home, capable of engraving copper and specifically taking FR4 PCBs.
Ordering PCB in Egypt is like pulling teeth, you have to wait till ur lil brother grows, and after it comes, you have to pay the customs with ur cidney, so no I'M MAKING MY OWN PCBs.
I knew it was a hard project, but damn, I didn't know I'd learn this far. This project helped me learn more about rigidity, motion control, mechanical fundamentals, and much more that I can't count.
