Read/Write NFC Tags

Does anyone knows if it´s possible to create own nfc tags for the UM3? The tags from the UM spools can be read from my Samsung S7, but the data format is unknown.

Yes, the tags can be read and written. What do you want to achieve?

We wanted to implement ndef records, but we made a mistake causing no other app to understand the data

hiya,

I wouldn't mind to understand this subject.

Being able to re-write these with data of a material that isn't ultimaker's like Ninja flex or if you prefer another brand of material or simply because you want to use a colour that UM can't supply. transfer the filament over to a UM spool and reset the data on the spool.

something like that anyways

bex

It would be a cool addition to the UM3 app to be able to read the tags. I have unmarked spools so can't confirm what the material unless I load it into the printer.

But I would also like to write my own rags somehow.

The tags only contain a material identifier, the actual data about the material is contained with the material database (in Cura and on the printer). So you cannot suddenly add ninjaflex without those being in the database.

But what if you could clone the TPU and *Name* it as NinjaFlex. Same with cloning say a CPE+ or nylon but naming it PETG.

In a way, that is what we are doing now....choose a profile in Cura that matches closely to what we want to start with and then choose the generic variant on the machine.

Although not a technically elegant solution, it could save a few steps for users and prevent the need to remember which variant you are starting from.

I bought a few spools on special of the non NFC ulitmaker filament and would love to be able to program my own tags with the material ID. I dumped one of the tags and it shows an NTAG216, but the memory space appears to only be less than half used. 

 

Has anyone had any luck creating their own identifier tags? I tried to SSH into my S5 to try and find the database for the materials but came up with nothing. (I attached my dump of my spool of Black Tough PLA if that helps)

One can retrieve a list of materials from the printer with:

http://xxx.xxx.xxx.xxx/cluster-api/v1/materials/

 

And all installed materials are available in Cura, in the program/AppImage folder (".../resources/materials") and in the configuration folder (".../materials" - in addition and optional)

 

AFAIK the GUID is the most important thing (if not the only one) that is used for comparison between gcode file and NFC data.

Boom! That was the answer. Thank you for this insight. Now I need to solve the the NDEF issue Daid mentioned above. Only done a cursory look into duplicating my tag without success, so I may attempt to write my own interface for the tags to write with my phone.
