Grbl

Grbl is open-source software that acts as the brain of a CNC machine, like a 3D printer or laser cutter. It interprets commands from design files and controls the machine’s motors and tools to precisely cut, carve, or engrave materials. Running on inexpensive microcontrollers, Grbl ensures smooth and accurate movement by translating digital instructions into real-world actions. It’s widely used because it simplifies complex machine operations, making automation accessible and customizable for hobbyists and professionals alike.
