Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

Thanks to XYLenTech you can now flash your davinci jr, but this will make it unusable. Has anyone found a way to put the old davinci firmware back on? If so you could just put the old firmware back on and you could do the chip reset.

I also wonder if there are 2 pins like the two you use for flashing the davinvi motherboard that would reset all previous data on nfc chips. If you could tell your printer that it has never seen the nfc chip that you have already used, you could reset it to 300m, this would eliminate the reason to do card swaps.

here is the link to the firmware flashing: http://www.soliforum.com/topic/13769/da … tier-port/

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

For anyone who has an EMUTAG and a Mini could you do me a favour?

Basically, I want you to allow the length remaining to run down to 0m.

If the printer  then tries to lock the card somehow, we will be able to see what it does - by virtue that it can't screw up the emutag.
It may set some dynamiclock bytes (high pages) - or even screw around with the password and pack!
This will be shown by the fact that the emutag will then show up as not being recognised..
You can then dump the contents of the card and we can see what has been done to the it. 
It may help us resurrect locked cards and enable them to be swapped...

It's not a 2 min job as you have to actually print to decrement the remaining length and also the batteries may not last that long .. as soon as you remove the batteries you re-set the emutag, so it will mean reading the values and re-writing them after.

OR

Can anyone with a card with say 10m or less left dump out their card detaisl for us to be able to create an almost empty card smile

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

Hi cgrillo

I just saw that you asked for someone with a low card to let the spool run to 0 and dump the card details. Is this needed for only the DaVinci Mini or can a Jr work for you as well?

I have a Jr card that has run to 0 would these values work for you? I had another card that has run to 0, but I have set the values back up and it seems to be working fine for me. My printer is still running version 2.2.0 FW so it is possible that it doesn't have the card gimp "feature" as yet.

A Jr would work for the data dump - but it needs to be low - not Zero unfortunately.
v2.2.0 on the Jr is a good FW to have - it doesn't care about refilled cards.

Would it help you at all if I were to set a low value on the card and run it then?

I have another roll (wanted to experiment with colours) that is currently on 90m but I have some prints I need to run so I can log some stats for you on it as its running if you think there is value in it. But i dont know if you will see what you want to see if my firmware isn't going to modify the cards

Not less than 10m but here's page 20 to 23 for 15.804m. I wrote them down earlier from some post where someone in some thread had posted those values.
20 0xbc3d0000
21 0xf42f3254
22 0xd441e2ce
23 0xceb04a76

However since it seems the current firmwares doesn't care about page 21 to 23 being valid numbers you should be able to setup an emutag with any remaining length in page 20 that you want and just print something.

First, Thanks to everyone for the work you are doing.
Second, Sorry for being such a noob.  New to this and working my way the first time.

I am trying to reset a tag that has gone to zero and use other PLA

I have an android device and have downloaded the RFID NFC Tools and read the tag.  I submitted it to cgrillo and got a UID and password back.

Here is where I am lost.  The instructable linked here shows a key in the upper right corner of the tool.  I don't have that key, nor can I see a n equivalent way to put in the password. In an effort to get somewhere I purchased the upgrade to the app thinking it might come with that, but it didn't.  The app unlocked says I can write "commands" but it is freeform and I don't know what to right or where to go from here...

PS: What is the PAK?

Any help would be much appreciated

I'm a noob with this too, but I think I read you can't let a tag go all the way to 0 or it is unusable, the printer locks it permanently. Someone correct me if I'm mistaken.

Yes, we think the later firmware's do indeed lock the tag - so be careful here.

2.5.1 Facts for both printer types
- Once the reamining length of the spool goes down to zero, the printer will lock the nfc tag irreversible. So never let the remaining length go down to zero. This is something that only happens in newer firmware versions.

Just a friendly reminder that we found out this fact ages ago. wink

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

TAKING DOWN A MYTH

Today i had recieved 2 TAGS from the user Chetosvsgeez (FW 2.2.7 as me). One of them was the original 100 meters spool that came with the printer, it was emptied to 0 meters, the other one is a normal 200 m spool with a few meters left.

I was able to reset both TAGS to 300 m. This means that TAGS aren't be blocked anyway when they reach to 0 meters (edit: at least on FW 2.2.7 and below), allowing us to print more that 300 meters with a single TAG with still the possibility of swapping that TAG.

I detected some unexpected changes (by me or my ignorance) in 2 pages,
The page #09 was slightly different to 00 35 42 44, i rewrite it to that value
Also page #0E was slightly different to 30 31 33 35, i had rewrited it too

I've also set the values of pages #0A, #0B, #14, #15, #16 & #17 to the values told on the first post of this thread

I don't know if pages #09 & #0E changed by myself have something to deal with any kind of blocking or even if they are important to set the values i'm talking to make the TAG being reseted from 0. I just changed them along with the other 6 pages values in both TAGS (# 0a,0b,14,15,16&17) and both of them were readed as 300 m.
Edit C: This is nothing to care about, i think that pages 0x09 & 0x0E were changed by mistake by chetosvgeeg, since never found this behaviour again

I'm also testing another thing ATM, i recieved a fresh spool a week ago, on that TAG i only performed the changes on pages #0A,#0B & #14. With only that 3 pages changed the printer recognize the spool as it was 300 meters as well. I don't know if it's going to throw errors when it reaches to 100 meters since i didn't reseted the other 3 pages.

Currently it's at 190 m +/-, i will update the info when it gets to 99 meters.

Edit: I can confirm this for firmware 2.2.7, there's no need to change pages "#15,#16&#17" on new tags (maybe used ones too?) to fully print 300 m, just pages #0A, #0B & #14. The printer allowed me to print with 98 m left. When i fully empty the Tag i will update the info again.

Edit B: Confirmed!, before inserting a TAG on the printer there's no any relationship between that 2 group of pages. (0x0A-0B-14 && 0x15-16-17). I have fully printed 299 m, now i'm at 1/5 print of an 68 meter model that have begun with 1 meter left on the spool, having printed on that Spool 299 meters without changing pages (0x15, 0x16 & 0x17). I just leaved the values that the TAG has from manufacturer, but setting pages 0x0A-0B-14 to be 300 m.

I've recorded a video with the proof, using the 0 meters tag marked with an X by Chetosvsgeez. Currently it's uploading to Youtube, and will be up in about an hour past the time of this post.


Edit: Sorry about my spoken english, i sound as i write... Terrible...

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

That's good news indeed.
What we now need to know is why are some tags betting locked? - and how are they locked as it could be a different password added or the dynamic lock its set (although I don't think this would stop the pages being read when the password is sent)

I have 2 locked tags that I can read pages 0-7, but the password is not accepted any more!
they are physically sound - i.e. no broken antenna

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

To be sure i have one TAG with 1 meter left pending to print. T'm going to send an 80 meters model to print, reset the TAG and send it to Chetosvsgeez. I'm sure that he will be able to print the 300 m. Because i thought time ago that blocked TAGS from DaVinci came only from unexperienced user tests on the TAGS and we all think that it was caused by the printer.
Edit: Confirmed

Also the only TAG i emptied ATM didn't change any LockBit. As far as i know, that is the only way to block NTAG213 bits.

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

If XYZ wanted to be nasty - they could change the password on tags that get to 0m
That way the printer would not recognise an emptied tag and it would also prevent us from tag swapping- as the password that the printer uses to identify the tag would then be wrong.

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

I only print from SD, and i don't have the printer connected to nothing but the energy cable. If any day i update my Firmare it's going to be for a downgrade, so i don't think this is going to happen to me or other users with firmwares from 2.2.7 to below.

Also we can block password page before emptying out the spool, or disable password auth... we will always have ways to counter effect each step they do.

Edited: Since yesterday i'm able to inyect temperature and advanced speed settings to 3w files from OSx XYZWare (never found a working pro version of the mac software), so printing from SD is enougth good for me now, maybe in the future i will want more flexibility to print and will end up converting to RAMPS, but not for now smile.

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

Yesterday I used a spool that I had reset to 200m on my co-workers da Vinci Jr. which runs a firmware of 2.2.7.

The spool was not empty, but for some reason it appeared as having a remianing length of 0m when it was loaded into the printer. After I had used to password supplied by these forums to reset the tag, the remaining length was read as 200m.

The events of the printer and tag are:

  • Printer was displayed and printing with the spool at a local shop

  • Printer and spool was bought

  • The shop did something (Trying to find out what, will edit when I know)

  • Took printer home and remaining spool length was displayed as 200m

  • Tag was reset with guide http://www.instructables.com/id/XYZ-Da- … eset-Hack/

  • After letting the spool sit in the printer for about an hour, the remaining length was displayed as 200m

I don't know if it is of any help, but I thought I would share that I got it working on a Da Vinci Jr. with firmware 2.2.7

i quote from the ebay page:

We ship worldwide, however some countries are excluded. We do not ship to Africa, Middle East, and Italy. We only ship to the confirmed Paypal address. We reserve the right to cancel any order for any reason at any time, you’ll be advised in that case.

regarding the device i assumed it was compatible as a reader are the tags usable too? i assumed we needed access to memory locations tha are usually locked in clear tags.
