Were you able to locate the files you needed, and since you do not have a NFC capable phone do you have the hardware needed to use the software? PM me!

Got it for 30 euros, I thought it would be cool. I want to try the NFC tag, but I couldn't find the project files for Arduino anywhere. I've tried from git a project that is called: https://github.com/sinitax/DaVinci-NFC-Writer , however the card reader gives error , so I guess the code for writing the card is not working properly.
Anyways, I was wondering if someone can at least give a working link for having something that could work for the NFC tags.
I don't have an Android Phone and I don't think I would spend more money in the printer, otherwise I'll just resell it.
Any help? Captains? Thanks!

I downloaded the Android app "Da Vinci Jr. NFC Unlocker Pro" (payapp sadly)
I set the NFC213 ntag details to:
Type: "PLA Old"
Color: Black
New Capacity: 200/200

This seems to work when i downgraded firmware (tool from this forum) to 1.3.7. Also 1.3.7 is the lowest firmware to work with Cura.

Both XYZPrint and Ultimaker Cura 5.1 is printing and recognizing this one tag that I am currently printing from. The UID does not start with 40 or end with 80 as I got the impression might be a must.

4 tags working so far in a row.

In my DaVin minimaker chip i have ONLY 7 pages. Cant read/write over 7. Can modify 04 and 05 only and this have no effect. What i can do to unlock new filament? smile
Good day

I practically can emulate NFC reader protocol fot 60% now.
but, i got one problem with Arduino, sometimes it loosing i2c packets (randomly) and everyting stop to works.

Looks it famous Arduino problem with working in Slave mode with 100kHz. Just not enouth CPU-speed.
I found simmilar issue there: https://www.raspberrypi.org/forums/view … p?t=170958

http://soliforum.com/i/?RjL4RU8.png
Maybe Arduino will be not enouth..., so trying to find solution

So good news.
I did some research, and is possible to use Arduino Uno (with ATMEGA328P) chip to emulate NFC reader.
http://soliforum.com/i/?H3UcNRL.jpg

3.3v is enouth to power up arduino.
I did some simple sketch, which emulate first 4 packets exchange, and that works.

this work spend a lot of time, and i'll be happy if somebody ready to help )

Just week ago i bought MiniMaker, an was "surprised" about DRM protection on the Plastic Cartriges.
I read the solution about NTAG213, but i think that is not my way.
I sniffed i2C bus, and fully reversed protocol between Controller and PN512.
There was a lot ideas about to use Arduino for emulate PN512, so i think that's real

http://soliforum.com/i/?r5VWKWT.png

Link for full reversed i2c traffic there https://cloud.mail.ru/public/wLAU/f2yVsDTg9
The dump file in .html because it's easiest way not loose font colors
if somebody wants to try make emulator.

There are hundreds of posts stating that recent firmwares do not allow tags to be "refilled".
You will need a blank tag to write to.

But it is written everywhere 2.2.7 and above. Mine is 2.0.2 so it should still work since it is under 2.2.7 no ?
Thanks for the answer

2.0.2 is indeed old - I think you may be right - I apologise smile

You must have updated something incorrectly for it to complain now - there's nothing you can do if you don't know the original values.
You'll still need one new tag to get yourself going again.

To be honest, I would update firmwares as printing got better in recent firmewares.

I read a lot but couldn’t find the answer to my problem.
I have a Da Vinci Jr 1.0 and my XYZprint version is 2.0.2 so I would be able to use reset tags.
I have my original PLA filament (100m, green) and went down to 3m.
Then I wanted to reset it and I changed the page 14 to 400D0300 following a tuto on youtube to reset it to 200m
Everything worked until I wanted to start a print : « Spool error unidentified spool »
I tried to change the numbeer of the page 14 but nothing worked and I didn’t wrote the initial value ...
I have read here that I should change the page 20 and 21 but not the page 14 as said in youtube. Moreover a lot of pages are not similar as it should be if I take this post as reference. But I did just change the page 14, nothing else.
Here are the informations of my tag :
http://soliforum.com/i/?8dkjxYh.jpg
http://soliforum.com/i/?xx2gB5F.jpg

So I guess I should find a way to reset the page 14 and then change the page 20 and 21 to 100m right ?
If someone could help me it would be wonderful !

Thanks
And sorry for my english

Currently using paper tags to use filament from other suppliers however I want to use Cura to really dial in settings. If I upgrade to the newest firmware will these tags still work? Should I just buy the smart tag?

I dont want to upgrade and find I have to buy the tag, when stock is limited, and find I cant print anything till it arrives.
