I got my PETG-CF and PAHT-CF today - both 1kg spools. But my mate opened both boxes and now I dont know which one which is… Babu does not write the filament type on the wrapping. I tried to read the NFC-Tag, but the wrapping seems to act like a shield and I cant the the tag.
I dont want open the PAHT-FC for now.
Has someone a idea how to identify the filament type without opening the bag?
