Bambu RFID HAS BEEN CRACKED!!! - Making Awesome 211

[@floridasaltlife]

Serious 3D people better read my comment to see the future !!! I was 40 years in the plastic business and Raw Material varies a "LOT" even within lot #'s. We bought a lot of large lots, truckload quantities were common and we often specified like lot #'s to minimize variation and even still we would sort by sequence #'s within the lots we brought in. We were very tight tolerance injection molders and charged a good premium for our precision. Our machines needed tweaking throughout the sequence #'s of these lots to maintain +/- .001" or .002" tolerances. All this to Say that BamBoo could be looking ahead to be able to vary their parameters programed into their printers real time even on same repeat materials by recognizing the differences throughout the lots and setting up their printers to optimize the roll of filament your actually install. This could reduce variables beyond what anyone else in the market could do... Think About it !!!

[@3DMusketeers]

we discussed something similar to this later on in the video, full feedback with the tags, but they would wear out fast, however if the average user could reflash them, you just clone it and go from there.

Would be better to implement a filament diameter sensor in the extruder to provide this functionality

[@robertmartinu8803]

@@xkeithedgex It's not just about diameter. More like the viscosity, flow rates, fusing properties and such at certain exact temperatures. That kind of parameters would be useful to ensure a repeatable product. Think more in terms of "whats the average length/weight of molecule chains in this batch" - the diameter and roundness can be controlled quite well by the filament factory, but their feed stock might have variation beyond their control.

I found whenever someone asks the same question the third time, I wrote a FAQ or web page on those, for a company where I worked. That is a great way to get rid of many questions and save a lot of people time. This was when I worked for an oil company back in the 1990s.

The standards that should be used from the get go is ISO standards for RFID. Regarding your industrial customers wanting the same material everytime, there is a reason why. They have RD specs to follow, the have prototyped, tested, and run production per the specs. If they are good at there jobs, they even created FMEAs and have created some sort of QMS. A change in material would require testing, sampling, customer approval (if required), and then changes to all documentation, purging old material out of the system, and maintaining a clean point to ensure no mixed parts. Its way more than just changing the settings in your slicer.

I have a picture of me at age18 working on the hubble main chassis. I always said it was the most expensive background, i have since worked on the f22 raptor, the seawolf submarine and the X-37B space shuttle. I have pics of me in front of each of them...i have a pic from a month ago of me in front of the b21 im awaiting clearance so i can bring it home.

[@MaheerKibria]

BambuLabs really should just work with manufacturers that want to in order to make this a standard. Bambu wouldn't even need to give their private key in order to do that.

[@dustindavis6700]

Bambu Labs should sell RF ID tags that you can set peramitters for a third party filament.

[@Wabbit0789]

Maybe having a USB handheld RFID scanner for your slicer? then it could work in the slicer its self and be available to every printer with out modding. That could be open source slicer will set the values for hot end, speed and bed temp. Then the multicolour systems can catch up. You could buy the scanner with the filament would be an idea. You guys can go with it, free idea

[@justinchamberlin4195]

The positive benefits of RFID tags certainly are intriguing, possibly even a major step to true push-button printing that still preserves the ability to use any filament instead of first-party filaments, but I'll always be suspicious of a printer that could refuse to print anything if the "wrong" manufacturer's filament is loaded. Sure, manufacturers may claim that they'd never do that, but I'd only put so much stock in those promises depending on the manufacturer (I wouldn't believe it at all from Bambu Lab and only would mostly believe it from Creality or even Prusa). I would like to see a little more info on just how not-open source the Prusa Core One is...there was a lot said in the intro video about being able to customize parts of the printer to our hearts' content, and people in the live chat were saying that they've even gone as far as to no longer require users to physically modify the mainboard to load custom firmware, but how locked down are we talking? Are we going to have to rely on, gulp, Creality to be the open-source leader in the mid-range printer market?

[@andreas.grundler]

As far as the Prusa Core One is concerned, Prusa has made everything open source in the past, e.g. with the MK3. This includes the STEP files for the prints, the CAD files for the printer itself and the Gerber files for the mainboard. The result was cheap copies from China, which of course isn't great for Prusa. With the Core One, they are a little more reserved. The printed components are only available as STL files and as far as I know they still want to release CAD files for the side panels so that you can create your own mods. However, the files for the mainboard and CAD files for the rest of the printer will no longer be available. The firmware is still open source. The company that currently offers the most open printers is Sovol with their SV08 and SV06 ACE for which they released CAD files and the firmware which is based on Klipper. But as far as I know no Gerber files for the mainboard either.

[@Serenityindailylife]

I take my old tags and stick them on a new roll of overture filament. It runs faster. I think they throttle back 3rd party stuff. My p1s never picks up the real bambu filament. It always has to manually fixed. They wont reslice because it would trigger an iso supplemental inspection in some cases. Iso is a big deal, it costs on average $100k

[@lonewolfsstuck]

With the Kobra 3 Combo and the ACE pro having RFID AND filament drying, i think it would be a cool feature to have the RFID information transmit drying settings.

[@jackcoats4146]

ultimaker has been writing RFID tags on their filament for years.

[@3DMusketeers]

stratasys was first

[@johntetreault]

My Android phone CAN read the Bambu tags...it obviously fails because it doesn't know the encryption keys .. but it identifies the tag correctly as a Mifare tag and attempts to read it.

[@roobtoob2]

I have a Bambu X1C, and I think it would be GREAT if I could take a spool of another brand of filament (take Creality CR PLA for example or just pick one), calibrate for it, and then store the material type, color, and flow rate to an RFID tag stuck on the spool. RFID tags are cheap enough. Then, the printer could recognize that particular spool again in the future if I remove it from the AMS and put it back later. I can do all that *manually* now, but have to redefine the parameters from my notes (or re-select the profile I saved) every time I remove and replace that spool. It would be great if I only had to do it once per spool (calibrate the K factor), write that info to an RFID tag, and have the printer recognize that spool on sight. I went out and bought a 2nd AMS, so at least I can keep eight spools loaded before I have to start swapping spools around.

[@filanfyretracker]

of course at the begining the mention of settings, I can understand at times why a big industrial machine might be locked in. I suspect they can only assure you of the structural properties if its extruded at x temp. I will say one thing an OpenRFID filament system could allow is keeping records of used filament like you said. My idea is that in an ecosystem like Prusa could be if you are using Connect maybe it would even be able to suggest a printer with enough filament for your job. On an XL could even have it auto suggest enabling spool rollover. Of course could also have Link directly talk to the slicer over LAN, And in sneakernet usage just have the printer generate say "Filament.cfg" or something on the flash drive and when plugged into the PC it would update the slicer on available material(s). 33:35 btw the QR code on a Prusa nozzle case opens their manual for changing a nozzle. how he mentions verifying filament and making sure its legit, this could find use case in fields like aerospace. You could prove that spool is from that mfg and as such matches the material data sheets you might require for a client to know what batch that plastic came from.

[@FreedomToRoam86]

I love my Bambu printer that just works great without incredibly boring dumb tweaking every little flow rate or retraction amount etc. I literally would not get a 3 D printer until Bambu’s came out because printers needing full assembly and figuring out settings was just not worth the cost and aggravation. And Bambu filament works great. But no PCTG, or recycled, or certain colors, etc. would be nice to have RFID for my non-Bambu filaments

[@AndreRuiz]

Can you clone a complete actual tag, including the signature? You don't need to re-sign if you just want to create your own tags based on existing ones. That's some thing already.

[@andyspoo2]

It seems like a lot of work for very little benifit. I have a P1s with a Bigttreetech Panda. It takes seconds on that screen to select PLA, Green Generic and the generic setting has worked very well for every filament I have tried (PLA at least).

[@versus023]

How can drying a filament for too long can ruin it?

[@ivansmith654]

What would Mitch say about the home made recycled filament that Uncle Jesse talk about on his channel?

[@3DMusketeers]

great question. I say not to trust that company until they are shipping

[@SteveLaird]

Isn't Rfid filliment part of Bambo's lawsuit?

[@3DMusketeers]

Alas it is

[@JJFX-]

This is why the community is so great and why I'll still never buy a Bambu. They're impressive machines but they lock too much away behind their walled garden in an industry founded on sharing information. Once it became clear people would put up with it Prusa began tip-toeing down that road as well. I realize not everyone has time to painstakingly build and tune their machines and just need something fast and reliable, which is fine. If they're smart they'll realize this only makes their machines more attractive. They're fooling themselves if they think people will avoid other brands of cheap filament but this shouldn't have much of an impact in the long term on their engineering plastic sales. Hell they'd probably make more money selling an intuitive, customizable RFID tag system people can just buy.

[@rsilvers129]

Bambu works with all filament so no reason to not buy it.

[@JJFX-]

@rsilvers129 That wasn't at all what I was saying. I just meant letting people use the RFID tag system with their own filament, which is the point of hacking it.

[@jerrygrimes8813]

The RFID is a "nice to have" for me. I have filament from other mfrs, and just tell the AMS what it is (usually Generic and the material type). It takes 3 or 4 button presses, and then I select the correct thing in my list, those that I've bothered to calibrate. For the "appliance operator" skill level, using Bambu's presets for both process and RFID filaments is a huge simplification. They just work. For many, that's worth a small premium. Anyone using "exotic" filaments, or maybe colors Bambu doesn't offer, probably has the skills not to really benefit much from the RFID capability.

[@derpymcderp42]

VORON RFID support ???

[@3DMusketeers]

that would be SUPER cool!

[@andreas.grundler]

@@3DMusketeers I have heard that BigTree Tech's multi-material system (VVD) is equipped with an RFID reader and they plan to support as many filament manufacturers RFID tags as possible.

[@3DMusketeers]

that would be stellar!

[@sibbeh]

DRM has no value, the data is the value for the consumer. All the data could be in an open format.

[@timo4463]

true :/ i mean i said it beforthey couldsell 10 tags for 5 bucks you can programm its still close source but you can use it

[@MarkDeSouza78]

Is it possible to clone a bambu labs rfid tag? ie if you have bought a black pla spool from bambu labs, can you copy the rfid tag and put that tag on say an esun black pla spool? I am assuming bambu is not tracking that number of meters have been used for a single filament serial number and that the non-writable parts of an rfid tag are used as part of hash signature

[@3DMusketeers]

It is but the formulas of the filament will be different and it likely won't perform as the same. We dig into that some in the episode.

[@XA-JJKILLERs]

Its a rfid tag they can be rewriten on

[@layeredwork]

@@XA-JJKILLERs The problem is, they talked about it, the signature. You can't rewrite a tag with a valid Bambu signature.

[@XA-JJKILLERs]

@@layeredwork yup i got to that part lol

[@josephgauthier5018]

Dont forget to get him in touch with BigTreeTech!

[@RandomMiscShit]

Game changer. My biggest concern with my p1s is Bambu deciding to lock the printer/AMS With their own filament similar to stratysys. (I hate stratasys printers for that reason, sucked buying parts for them).

[@rsilvers129]

Bambu doesn’t lock it to their filament! They only use RFID for user benefit.

[@3DMusketeers]

currently they do not lock you out, but that can be something that could occur.. Likely, no, but possible, yes.

[@jimmanis6717]

There are a lot of filament profiles in Bambu studio as well. Nothing locks you from using any brand. It's just a good way to get to printing reliable parts without tuning each brand/type/color/ batch or lot numbers. It's honestly just a good system and the prices for refill rolls is extremely competitive and has much less waste than a new spool every time you get a spool.
