The CNC router's firmware? The CNC controller itself is dumb as hell. It's connected via serial to an old offline computer that's only job is to pipe G-code over RS-232. Not even to "load a program" to hold in memory on the controller. Literally to stream the commands to the machine.

My CNC controller has an SD card, Wifi, Bluetooth, and USB. They're not all the same.
Fancy!
