Printing with Prusa PETG-CF on Core One

How do I get the printer to recognise a PETG-CF bgcode file produced by Prusa slicer?  I did select in the slicer "Prusament PETG Carbon Fiber".  But the printer firmware doesn't have a matching filament type it seems.   (I am using a hardened nozzle. )

You can add a user profile for the filament on the printer menu with the temperature specs for nozzle, bed and probing temperatures and an appropriate name. Somewhere in the filament menu, manage filaments, or something like that.

The matching filament type is simply "PETG"

Maybe, but isn't that going to have the wrong temps for PETG-CF?  Perhaps I can go and change them, but then that messes up any standard PETG I want to print?

The temperature the filament prints at is set in PrusaSlicer for your filament profile, not the printer firmware. The firmware temperature is only used for load/unload/purging filament etc. Otherwise you can create a custom filament setting. However the set of filament types in the Filament properties in PrusaSlicer is fixed. So if you create a PETG-CF filament in firmware, it will trigger a "wrong filament" loaded warning that you have to manually ignore. It's just better to set it to PETG.

I did create custom profiles some time ago for PCTG on my printers. This previous posting has photos of the menu screen for this:
