Not true. You can send it .ini files
Nallath, can you elaborate how to pass .ini files to the cura engine command line slicer? When looking at the help page (CuraEngine help), I don't see any option to pass a ini file.
If this is not possible to add the ini file, I wonder if it is possible to add the ini variables to the json file provided in the Cura/resources/machines/ directory.
