Find your Cura settings directory:
- Windows:
%APPDATA%\cura\<version>\ - macOS:
~/Library/Application Support/cura/<version>/ - Linux:
~/.cura/<version>/
There should be subdirectories definitions, extruders, and scripts. Copy the files from this repository into the matching subdirectories, and then (re)start Cura and add your new printer profile.
The Creator 3 Pro seems to be unreasonably particular about G-Code format and order, so a post-processing script is required and must be manually activated from the Extensions->Post-Processing->Modify G-Code menu. Make sure to enable 'FFC3Pro Post Processing Script' in addition to any other post-processors you may want.
Once you have the printer profile installed, you may want to import my recommended settings using the .curaprofile file. These settings contain some further changes to the machine properties. From there, you can modify and create your own settings profiles.
