Getting Bambu filament is a bit scare at the moment.
Anyway, I was looking forward for this new feature in the update of the FW for AMS (reading the patch notes it seemed that it would be available generally, but when looking on the printer screen you can read that it is only available for Bambu filaments). How is this measured? Is there a weight cell? And would it be possible to extend that to non-Bambu filaments (e.g. by providing the empty spool weight)?

From my understand it is calculated by pulling exact length of filament and seeing how far the spool has rotated using the RFID tag, reason its only for their filament is they know the exact size and can use the above info to calculate.

Thx for the explanation - then it makes sense that they don’t implement it for other brands

My plan since Bambu isn’t selling the RFID tags by themselves for colors etc is to order in a color (if they ever get any in stock) and then use that spool and RFID for other refills of the same color or to move 3rd party filament over to that spool. I printed out 2 adapters to do it with the drill, one for normal size spool holes and one for larger size. Both work quite well.
It should be realy easy to reset a spoolcounter and subtract the amount of filament printed, why so complicated with rfid tags?!
Because they want to push their system.
Because measuring is more accurate than calculating.
Because implementation in SW is easier.
More likely it’s because they can’t identify a spool that doesn’t have an RFID tag on it. How would they know if you swapped spools or moved the spool to another slot or AMS? How would they know if you put an already-used spool in?
I don’t know if they do this, but I can imagine that they may also write the remaining length back to the RFID tag itself. More likely they just keep track of the ID# and quantity in the cloud or something instead, though.
