Is there any progrss ? #4
Comments
Yeah, would like to see any progress, too. Reading and writing custom RFID tags would be really awesome. |
Would love to know this too! Can't wait to have RFID tags on all my spools |
Hello all! I have gathered all the following: Spools sold by Bambu on their site including their hex identifier posted. That is type, color, and hex code. I am in need of assistance with the following: Decoding the crc and keys from the dumps of the rfids. Let me know if anyone has anything to add to the above or if we should start a discord group to more proactively (and privately) communicate on progress. |
I do have Proxmark3 and ASM, but most valuable thing is that im developer i can do mobile, desktop applications (Maui c#, flutter, c++, java), also can do webs(Js,Blazor, React, Svelte)... Let me know how can i help.. There is also possibility to established the annonym server to host this data, ot at least api for Desktop application.... |
Hi, I can have a try at the CRC cause I have a lot of experience with it, if you post a complete hex output I can try reverse engineer it. |
Tiagojanz, do you have discord? I'd like to discuss further. If not discord then lets find some way to take this conversation privately. Perhaps posting temporarily a file link we can dispose of after we exchange contact information.Sent from my Verizon, Samsung Galaxy smartphone

What about dumping the firmware from the AMS? Possibly that would shed light on the decryption process? |
I have the ability to do chip off read dumps and am willing to do the solder work to remove and read the chip and replace the chip onto my unit. However, unless there is a terminal interface or some way of communicating with the chip through a firmware upgrade/recovery or something, decoding the binary and assembly of a bin file is out of my expertise.
Yes, having both sides of the process decoded and referenceable will significantly improve our chances of manipulating and making custom firmware/software to leverage the AMS… Imagine the uproar if we made the AMS USB compatible and could use it with ANY printer?! That is likely territory I do not wish to tread on due to legality and rights issues.
But, updating the nfc tag for spool consumption and color change? Sorry if I feel that is square in the rights of the consumer to be able to manipulate even if it does effect a “small” amount of sales from bambu filament.

Hi, I've added you also on Discord, I'm interested to join in. -- Regarding spool consumption, it is not written on the tag ? Consumption is kept on the AMS, I suppose, right ? |
also add your to discord... |
did the discord happen? interested in what others have learned and happy to lend a hand w/ a logic analyzer or scope if useful, or hunt down uart/jtag/spi if i can source a parts only ams |
Has anyone started working on an automated key retrieval process? Specifically this part from the documentation: https://github.com/Bambu-Research-Group/RFID-Tag-Guide#getting-the-other-keys-by-analyzing-the-log-file @warbarz ? |
I have joined one person in discord to discuss who has a good grip on the proxmark stuff. He has posted his discord I believe.
I myself have not gotten to dumping bins for him yet. I have all the bambu spools, colors, types, etc. I have a proxmark and 2 ams units. I just havnt had time to dedicate to this between using the printer, working, and family.
I would like to work directly with everyone in a discord chat so I can be more useful and perform specific requested time limited functions, like a bulk dumping of the spools I can do over time and post the results as I go… but I need to be told how and what to produce.

I've made some scripts. Also, I just created a Discord server, it will perhaps be easier to discuss this : https://discord.gg/K7eqWwUs |
Discord invite is not valid anymore :(
