Official firmware downloads can be found on Creality.com in the 'Downloads' section.
Note: If you have a CR-6 MAX or CR-6 SE with v4.5.3 board (instead of v4.5.2) you need to have a specific firmware release for your board. The regular releases are not compatible.
Community firmware, based on a newer version of Marlin, can be found on the community firmware GitHub page. Be sure to read the readme accurately.
Note: Support for the CR-6 MAX and CR-6 SE with v4.5.3 board is present, but you will need to compile the release yourself.
