I have a K2 pro on order through the presale and want to find out about the RFID used in the filament. Will Creality print interact with the printer for RFID information? I have heard that the RFID will be signed like Bambu does, it would be nice if users would be able to program RFID chips ourselves as I do use Hyper PLA but also like eSun PLA+. Alternately will RFID stickers be available to put on non-RFID spools that I have purchased from Creality, I have a lot of them. I am holding off on buying more filament till I can learn a little more about how it will work, how it interacts with Creality print and the availability of RFID filament. I usually buy a few dozen spools at a time and don’t want to have a problem.
Update Creality got back to me:
“Purchase hyper pla alone is a paper spool, there is no built-in RFID tags, e-commerce subsequent shelves with RFID tags for sale. Currently does not support self-editing RFID chip content, whether the subsequent development depends on the product program, please pay attention to the official website information.”
I checked and they are not listed on the US store yet.
It would be great to create rfid tags to add to existing, as well as spools from other suppliers. Though i see an issue. What data is on the rfid and how does the printer respond…
Is it just:
Material
Colour
Size
Or is there more detail on; temperature, speed, moisture, age, batch…
Material, size, color, date and manufacturer would seam to be the correct information. Things like temp and speed depend on other variables such as printer and environment. A min max could be added but don’t know how useful that would be. The slicer or other software would need to keep tables for different printers and environments. I live in Florida ie high humidity my settings would be different from someone in Arizona low humidity. And someone in Alaska would need different settings as the cold weather and dryness from artificial heat would make it much different.
That makes sense, though looking at Creality slicer for K2, it seems to hold quite a lot of spool info but I’m unsure. Cross platform rfid is the only way rfid will be useful, inc making your own rfid stickers etc. Time will tell.
Once I get a spool with the rfid in it, I will scan it and see what info is on it and which protocol it is using. I should be able to replicate it as long as it is an industry standard. Fingers crossed. It would be nice to be able to program your own color codes and temps for each type/ color. Especially when you use other manufacturers filament.
We shall see!!!
If it is signed then it can’t be copied unless you have some hacking equipment. If the code for the RFID reader is open source then the community will create what is needed. Creality did get back to me and the spools don’t come with the chips they are sold separately and they don’t support user created RFID. You could use the RFID tags cross platform and be close, i.e. use a Creality Hyper PLA tag on eSun PLA+.
Thank You for the info Dan. I know that they will probably lock their tags but I should still be able to read them. I work in an industry where we use rfid for a bunch of different things so I should have the tools I need to hopefully make My own.
I know that one of the content providers was displaying plastic hyper rolls with the rfid in them already. You would have to have one for each color if purchased separately. That would become a pain I would think. Even just keeping track of which one is which.
The US store now has the Hyper PLA with RFID for $2 more than the non RFID. As it is a plastic spool I can understand the extra $2 but how about stickers for the 50+ cardboard spools I already have.
I have a question on the RFID on Creality filament. Does anyone know what chip/format it is? I am still waiting for mine so I don’t have one to check out yet.
Also I see posted that the info stored includes the amount of filament left on the spool (also see this posted on Bamboo) but how can it do this if it only has 2 readers, only 1 of the 2 tags on a spool can be accessed by the CFS?
The tags will be unique. Hence printer knowing which spool is in the CFS or side spool holder. The printer is recording use, not the rfid. Sadly the code is locked for the time being so there is no way to make your own.
Did you see https://www.youtube.com/watch?v=SdHqzZnYCCs this is a pretty good described way to find keys etc.
But I’m waiting for a cfs (maybe self built) which you can connect to a pi or something else and read whatever rfid and the optimal settings and can heat and dry probably, too.
Has someone got an answer what could be done with a lot of other pla bought for the former CR-10 where rfid was not an option/question? Can that be used in the CFS and/or can we set an own rfid tag written and placed on this spools (using either no sig at all or at least something more open like letsencrypt)?
Once I get my proxmark 3 I will try to figure out how to make an identical copy of the RFID tags for Creality Hyper PLA, can then use them on non-rfid spools instead of respooling to a used RFID spool.
