Filament Internal Code #42

spuder · 2024-10-23T01:12:41Z

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

WolfWithSword has documented most of these internal filament codes

https://github.com/WolfwithSword/ha-bambulab/blob/78cc6bda14ef0f82e74b59afc745cc5534c01a5e/custom_components/bambu_lab/pybambu/const.py#L40-L62

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

spuder · 2024-10-31T15:01:22Z

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.

Sounds amazing. I'll be following this pretty closely.

That sounds really cool! Is the following valid from your opinion to recognize custom filaments with the AMS?

Equipment

Proxmark 3 easy RFID Reader
compatible 13.56MHz RFID chip as described in this issue
Any computer running your flask app

Work Flow

Set new custom filament in Bambu Studio, generating a unique ID for it
Have RFID reader connected to computer running flask app
Flask app connects to Bambu Lab printer via API and MQTT
Scan RFID chip via flask app
App retrieves filament list with newly generated custom filament data
App connects RFID chip data with new custom filament ID and writes back to Bambu Lab printer
Stick RFID chip to custom filament spool
Printer will recognize the spool from now on with all data

Is that right or is something missing?
Thanks in advance for your help.

No, it's much easier.
Right now i'm using a barcode reader, the module for reading RFID chips is not yet implemented.
Since only the unique Filament ID and color is read from the QR-code or from the RFID tag (when implemented), you don't need a Proxmark3 and you can use any RFID tag.
At the QR-code or the RFID tag (when implemented) is only the UUID and the color-code stored, everything else is configured in your Bambu Studio filament profiles.

Work Flow:
prepare a filament spool:

Open the Website, the Flask App offers and login to your Bambulab Cloud Account (LAN only not yet tested, but should also work). The generated token is stored and used for all requests.
Open the Filament page, the app is fetching all filaments and sort all builtin and custom filament profiles.
select filament and the color. Either apply this settings to your printer directly or print the generated QR-code and place it on the filament spool (later there will be a button to store the information on a RFID tag)

print with this filament:

The app is reading over MQTT the AMS and is getting all empty AMS slots.
If you scan a QR code (or later the RFID tag) the App will set this filament to the most left empty slot.
Load the filament spool to the most left empty slot and you will see the selected filament in the device tab of Bambu Studio.
Press the sync button in your prepare tab.

This is absolutely amazing, you rock! 🤩
Have to try that asap. Will the RFID option utilize the onboard reader of the AMS to recognize inserted spools?

Fixes #42.

pelrun · 2024-12-07T17:10:06Z

FYI BambuStudio has all the filament data in .json format including the filament_ids, so you don't have to jump through hoops to get the latest list (note, only the *base.json files have the id): https://github.com/bambulab/BambuStudio/tree/master/resources/profiles/BBL/filament

I'm working on a project that uses a color sensing module to scan in all of my filaments inside of a drawer system I setup, that's categorized by material, everytime I tap a button. An ESP32 will send the colors of each spool to an RFID chip that will program a blank RFID sticker, the type Bambu uses.

This was the only missing piece, thank you

@CodeBradley Will you make this project accessible on Git? Sounds interesting
