NFC / RFID reading not working

Hi,

my NFC / RFID is not working. Or to be fair, only in 1 out of 10 changes. But it is not dependent of the filament or the roll. And not from the position 1-4. Or From its distance to the 2 NFC Readers.

Now and then its working … what can I do or check to improve this situation?

P.S. Of Course i am talking about Bambu RFID abled filaments.

Whenever I have a spool that won’t read I just unplug the AMS and plug it back in and 99% of the time it will read it after the reboot. Maybe someone else has a different method but this has been easy enough for me and almost always works.

super, that worked, thank you!

Have the same issue. Reboot of AMS solves it. Thanks for letting us know.

i have this same issue with the ams lite.

you mean to unplug the ams when the printer is turned on or off?

what i do is:
i turn the printer off and unplug the ams then i turn it on without the ams
then off again
then i plug the ams and turn on the printer
it doesn’t fix the issue :cry: the feeder indicator keeps blinking

Hi there!

My AMS light is 6 weeks old and just started not recognising a filament change - only BL filaments witch all formerly was flawlessly recognised.

Rebooting, disconnecting - no effect.

Only one petg filament roll ist recognised - on all 4 filament slots.

Hello,
I see a lot of people with the problem that BL filament tags are not recognised. I have the same problem only with slot 2 on my AMS Lite.

Has anyone found a solution yet? Or filed a support ticket with Bambu?

I am having the same problem and reported it to BL 6/28/24… Let’s see if it gets fixed.

My A1 is 3 days old. Not read any of the bambu tags.

RFID uses weak radio signals to read the tags. I don’t know what frequency the reader works at, but it’s possible it’s simple radio interference (that may not be so simple to correct for).

Do you have any big transmitters nearby? Radio stations, construction or other offices that may use radio dispatch? Or are there times of day where it does work?

Might not be interference too but RFID is kind of elegant how it works and needs a fairly clean background to work.

I had one of my mesh routers sitting right next to my printers, literally inches away. I moved it to another room maybe 20 feet away and that seemed to fix the problem.

I could see florescent lights creating an issue as well.

I had a green PETG HF lose its identity in slow one sometime during a print while it was being used.

Reboot didn’t help it. Swapped with slot two(PETG translucent). Slot 1 read PETG translucent, slot 2 wouldn’t read PETG HF Green. Swapped green with PETG HF Red, it wouldn’t read.

Actually, during initial load of either Green or Red, it’d flash up accurately, but then go away.

Swapped out Red for PETG HF Black, it read and stuck. Switched back to Red, it read and stuck. Switched back to Green, it read and stuck…

Don’t know what the issue was.

When it wasn’t reading, I tried manually setting it in Handy, after saving, it’d go away, showing only a ?.
