Your 3D printer firmware is the system software that controls the movement and operation of the motors, heating elements, and other components. We might call it the brain or engine of the machine, and it's usually stored in the printer's microcontroller, a small computer programmed to accept commands from the user. There are several 3D printer firmwares to choose from such as Marlin, RepRap and Klipper.
