CORRECTION: I have figured it out!
I had the 0.2mm nozzle loaded.
If I change to the 0.4mm nozzle, PLA-CF shows up normally again.
I suggest making a better error message for this:
Example: “NOTE: The filament of type $TYPE_HERE in your AMS is not compatible with your nozzle, please change the nozzle or filament type.”
I’m seeing the same problem with PLA-CF.
In the Device tab, it shows up as PLA-CF in the AMS.
But when I sync, I get an error about filament types and it shows up as ABS.
“There are some unknown filaments mapped to generic presets. Please update Bambu Studio or restart Bambu Studio to check if there is an update to system presets.”
I seem to recall not having this problem with this filament last month.
I had to (re?) enable PLA-CF and PLA-Metal in the Filament Selection and PLA-Metal now shows up, but PLA-CF doesn’t.
I think Bambu Studio forgot what PLA-CF is and is now ignoring when it is installed.
