Marlin Firmware

Marlin Firmware is an open-source firmware project that provides a driver for 3D printers and related machines. Its website offers firmware downloads, configuration and installation guidance, documentation, development resources, and tools for working with printer settings. Users can find instructions for configuring boards, probes, displays, and features, alongside guidance for contributing code and reporting bugs.

Marlin supports a broad range of motion and machine-control functions. Its documented capabilities include automatic bed leveling, linear advance, input shaping, filament runout detection, firmware retraction, temperature control, and power-loss recovery. The documentation also serves as a detailed reference for G-code commands used to control movement, heaters, fans, probes, storage, and other printer components. Additional commands address laser and spindle operation, CNC workspace planes, and coolant controls.

The site provides utilities such as bitmap and RGB565 converters, calibration tools, and links to the source-code repository and bug tracker. Overall, Marlin Firmware combines downloadable printer-control software with technical documentation and practical resources for configuring, operating, and improving supported machines.
