    "Bambu's AMS wiki says the official roll has a tag on both sides, and that reading rotates the spool. The AMS has to be idle. If filament is already fed out, the wiki says the read cannot run.",
    "The same wiki estimates remaining filament from how much filament feeds during one full rotation of the tag. A full 1 kg roll is 100 percent by default. That is an estimate, not a scale.",
    "OpenSpool's RFID page lists NTAG215 and NTAG216 as supported and NTAG213 as not supported. Its sample JSON is an example record, not a nozzle setting for a real spool."
  ],
  "pros": [
    "The Bambu behavior is the wiki, including the idle rule and the 1 kg default, not a guess about what the chip encrypts.",
    "OpenSpool and OpenPrintTag are described from their own pages. A third-party chip is not written up as if Bambu reads it."

  "cons": [
    "The comment that says someone wrote to Bambu about editing a refilled tag is truncated. Bambu's answer is not in the comments, so it is not quoted.",
    "Prusament NFC reuse is a thread title with no comments."

  "community": "The editorial summary says third-party RFID exists and is not needed to print. r/BambuLab 10wve38, score 2, is truncated. The visible part says the poster wrote to Bambu asking whether they could read, edit, and write a tag after refilling a spool with another manufacturer's filament. Score 1 says respooling onto Bambu RFID spools and using a custom preset works generally, with occasional tangles when the spool falls off the roll. r/BambuLab 13q188w, score 81, says it probably tells you to get it out of the AMS. Score 36 says a one-cent tag already on the manufacturing line is cheaper than a second line, and mentions a future AMS design.

      "q": "Can I write a Bambu tag with another filament's settings?",
      "a": "Not from these sources. The score-2 comment on r/BambuLab asks Bambu that question, and the bank cuts the reply off. Bambu's RFID-board wiki says the board reads type, color, and production serial number from the tag on a Bambu spool. It does not publish a write method for a third-party refill. [AMS filaments](/answers/ams) is the feeder page. [Bambu filament](/answers/bambu_filament) is the spool page."

    {
      "q": "What does OpenPrintTag say it stores?",
      "a": "The OpenPrintTag site, read 25 October 2026, says it is an open-source Prusa Research standard, that a printer can read and write the spool, and that live data such as remaining filament can be written back onto the tag. It says a blank tag can be stuck on any spool and that the tag works offline. It does not list a nozzle temperature."
