Filament Internal Code

[spuder]

Dumping the mqtt messages I've identified an internal code that is used for filaments

WolfWithSword has documented most of these internal filament codes

You sir are a gentleman and a scholar. How are you dumping the mqtt messages like this btw? His script looked home assistant based.

To get the mqtt messages use mqttx

mqttx sub -t 'device/$SERIAL_NUMBER/report' -u -P $LAN_ACCESS_CODE --mqtt-version 3.1.1 -h $IP_ADDRESS -p 8883 -l mqtts --insecure

The mqtt api is documented here:

https://github.com/Doridian/OpenBambuAPI/blob/main/mqtt.md

The 2 main endpoints are /report and /request

For example to change the filament color you would do a request with a json payload like this

{
    "print": {
        "sequence_id": "0",
        "command": "ams_filament_setting",
        "ams_id": 0,
        "tray_id": 0,
        "tray_info_idx": "GFG99",
        "tray_color": "F72323FF",
        "nozzle_temp_min": 220,
        "nozzle_temp_max": 270,
        "tray_type": "PETG",
        "setting_id": ""
    }
}

you can query the Bambulab API and you will get a full filament list, also with your custom profiles. each filament has a uniq ID, also the custom profiles. You can have a look here, how you can read the filament list over the API: https://github.com/capull0/BambuAMSCtrl I coded this flask application, which will make the Bambulab RFID tags obsolete. Is working flawless since weeks.
