Firmware Firmware refers to the embedded software programmed into a 3D printer’s control board to manage its functions. It acts as the bridge between the printer hardware and the slicing software, interpreting G-code commands and executing movements, heating, and extrusion. Popular firmware options include Marlin, Klipper, and RepRapFirmware, each offering customization and features for different printer setups. Updating or configuring firmware can unlock advanced capabilities such as auto-bed leveling, thermal protection, or filament runout detection. Proper firmware configuration is critical for ensuring printer reliability, safety, and optimal performance. Users often customize firmware settings to match hardware upgrades like new extruders or sensors. |
