Replacements

Listings that take over the same core job as RepRapFirmware.

  • Klipper

    Run 3D-printer control across a Linux host and the printer's microcontroller.

    FreeOpen sourceLinuxSelf-hosted

    Klipper runs control across a Linux host and the printer's microcontroller and adds pressure advance calibration, but it needs a compatible controller, a Linux host and careful configuration.

  • Marlin

    Control compatible 3D printers with configurable open-source firmware.

    FreeOpen sourceSelf-hosted

    Marlin supports many printer-controller boards rather than a limited set, but the firmware must be configured for the exact printer and electronics.

  • Kalico

    A community-maintained fork of the Klipper 3D printer firmware that accepts features upstream considers risky.

    FreeOpen sourceLinux

    Kalico is a community fork of Klipper that runs on a Linux host and adds riskier features that can damage hardware if misconfigured.
