Yes, that is values for 200m remaining length. All unused 200m rolls should have the same numbers in page 20 to 23.

The checksum for 300M in Page 21 is A8 81 36 54

Yes, that we can now calculate but we still do not know how to calculate page 22 and 23. Still the numbers for 299.722 is good enough. I guess we could even get closer to 300 than that with a few tries. I wonder what happens if you have a full 300m roll and start a print and then cancels the print while it is warming up the extruder? Or if that doesn't work you could cancel a print just as it starts and only have used less than a cm of filament.



Ok, I was able to get pages 22 and 23 before and after I initialized a print but before it actually printed.Attached are the results. Hope this helps.

Could we start a new thread for this work?

Excellent!

The before value of page 21 indicates a remaining length of 256.916 meters but the after values (all changed from before) has a page 21 value that indicates exactly 300.000 meters.

That means we now have the perfect reset value for 300 meters for page 21 to 23.

Good work!

EDIT: You're right, wrong thread for this, but I think our work here is done anyway. We have the perfect 300m values now.

Re: Davinci Jr and Mini Regional Tag Swap

I am interested in swapping with someone in the United States, I just got my Da Vinci jr 1.0 (w) for Christmas, and am down to my last 10m of filament that came with the printer.  I got new rolls on standby, but wanted to look into swapping with someone to use this method to use cheaper filament.

I'm sure that who I swap with can help me better understand the card reading process and how to use this efficiently.  Seems like a good workaround that is helpful, as long both people are happy with what they get.

I do not have an android phone though, and not familiar with arduinos, or anything similar.
Is that a huge requirement for writing to the card?

Hello together .

I'm from german and I started with tag swapping today. When here more germans so let us know smile

Re: Davinci Jr and Mini Regional Tag Swap

We were able to set the NFC chip for the mini to 300 meters and it printed. Bozotclown1970 and I recently made a tag swap and he originally reset the card he sent me for 200 meters. However after sending it he suggested that I try setting the remaining filament setting to 300 meters "before" I put it in the printer. So when I received the card I made the suggested changes before putting the chip in the printer.  I only made these changes:

  (0A) E0 93 04 00
  (0B) E0 93 04 00
  (14) E0 93 04 00

When I put it in the printer it originally said I had 300 meters remaining on a 200 meter roll.  I printed a test item and took the following screen shot after the print was complete

I have printed a few more items and all is working fine so far.

Interesting, when I tried 300m on my Mini W it said 300m/0m (%inf) and refused to even send the print to the printer so it was XYZware that refused, not the printer. However I used the latest MacOS version of XYZWare, what version of XYZware are you using?

I am using the windows version of XYZware-2.1.15.1 and my printer version is 1.0.0. 

Here is a link for XYZware-2.1.15.1: http://www.filedropper.com/xyzware-21151

Re: Davinci Jr and Mini Regional Tag Swap

Hi, I live in Istanbul - Turkey. I would like to swap my tag anyone near to me.

I tried two passwords (thanks to Bozotclown1970 and cgrillo) but can't authenticate. Also I'm getting "unidentified spool" error now.

Printer: DaVinci jr. 1.0w
Firmware: 2.3.3
Tag: 100m Yellow Demo spool (Only used 20m/30m)

There must be something different in these demo spools.

I have had issues, have read someone else had the same and now you also.

Has anyone managed to authenticate a demo spool?

Re: Davinci Jr and Mini Regional Tag Swap

Folks that own a MINI. It is my understanding that the only time a password is needed for you is when the tag has not been identified by your printer. This will allow you to set the length to 300M. Other than that your printer cannot use hacked tags. If I am wrong someone please correct me and show me the results of a hacked tag on a mini.

Re: Davinci Jr and Mini Regional Tag Swap

I'll shortly be coming up to my first empty tag (>0m remaining) so I'm game to contribute to the cause!

Anyone in the UK want to try a swap?
I've got the code for my NFC already, so I'm happy to pack that all up and send that somewhere in the UK (Maybe mainland EU, at least before Brexit is complete!)

Count me in Bozotclown1970 smile

Re: Davinci Jr and Mini Regional Tag Swap

Hi all,

I will be interested in swapping tags, I have 3 tags 2 unused that I will get though in the coming months,
I have one tag that has less than 80m left on it and I will be willing to swap this one very soon. I am based in the
UK however willing to swap across Europe.

Many thanks
Simon

Re: Davinci Jr and Mini Regional Tag Swap

Just to let you know, I've found someone near me with the same make/model of DaVinci running 2.2.7.

I'll be seeking some new NFC codes and testing these shortly!
Will post results as soon as I get this done.

Just to make sure I don't fubar this:

1, reset spool to max capacity via NFC
2, try spool in other printer

^ this is my order of operations, yeah?

Yes, that's the order.
If you make a mistake the printer may permanently reject that card as it may see it as a modified one  - so make sure you do it right first time...
If in doubt.. ask smile

I'll likely post the card details before I load it, I've never reset a card before, so I want to make doubly sure I don't FUBAR it before I go in.

Any advice? I'm fairly competant with tech - not to the logic levels in the megathread, but I can follow that instructable, and I know how Hex works smile

74

Re: Davinci Jr and Mini Regional Tag Swap

Please add me to the USA swap list.  I'd like to swap a card soon.

I have the Minimaker running 1.0.5 (I upgraded the firmware before realizing this thread).
Software is 2.1.18.3.
(both of these authenticate with the internet as the latest).

So if swapping doesn't work, we'd know.

Re: Davinci Jr and Mini Regional Tag Swap

Hi

I'm in the UK and got a mini w for Christmas - I'd appreciate it if someone was willing to send me a tag that will work already set to 300m.

I only have the one tag (from the 100m the demo roll) so as soon as yours arrives I'll post out mine. (I won't let mine get to 0m) .

Unfortunately none of my phones have NFC I so wouldn't be able to do anything to the tag at my end but if anyone could help me out it would be great.

Please pm me if you can help.

Thanks Steve
