[Thomas Sanladerer] shows how he makes PCBs with a CNC machine and has a lot of good ... he uses FlatCAM to convert the Gerbers to a single G-code file that integrates the paths and drill files.

[Mhouse1] has a different idea: use FPGAs as CNC controllers. FPGAs inherently handle things in parallel, so processing G code, computing ... to get started with our tutorial on cheap FPGA ...
