The original
Kalico
A community-maintained fork of the Klipper 3D printer firmware that accepts features upstream considers risky.
Replacements
Listings that take over the same core job as Kalico.
Klipper
Run 3D-printer control across a Linux host and the printer's microcontroller.
Klipper is the upstream firmware Kalico forks, keeping the same configuration structure and documentation but leaving out features considered risky for hardware.
RepRapFirmware
Control supported 3D-printer electronics with configurable firmware.
RepRapFirmware is GPL-3.0 firmware with networked control and configuration files, but it only runs on supported controller boards such as Duet electronics.
Marlin
Control compatible 3D printers with configurable open-source firmware.
Marlin is GPL-3.0 firmware running on the printer board itself with no Linux host, but it must be configured and built for the exact printer.
