XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking (Page 8 of 31)

Cgrillo has a couple of examples on how to do that on page 2 of this thread.
So for 100m it would be:
page 20: 0A 86 01 00 <- 0x000186A0 (100.000m)
page 21: E8 94 33 54 <- 0x000186A0 XOR 0x54321248 = 0x543394E8

Enjoy your stay in Germany.

Meanwhile I have an Android to read the rfid. When I use NFC Tools I get a lot of information (NTAG 203 and so on) but no hex data. By using RFID NFC TOOLS I get no information at all.

Can anyone help me?

thanks a lot cgrillo. I have one phone left to try....=o

What do you get?
Post a screenshot

The card is being identified as a mifare ultralight c.
It's not, it's a ntag 213
Not a lot can be done if it's identified incorrectly.
I don't have an android and so can't help at all, apart from saying "have you rebooted the phone"

It does show the serial number though, but that really won't help much if the card type is identified incorrectly.

Silly question, but did you turn on NFC in the settings of your phone?  My Samsung 97) has an NFC icon i the status bar on the top of the screen.  I do not see it in your screen shots.

There is no icon shown on top. But I did manually switch NFC on. When I didn't , the program told me to turn on.
I have 3 more tags to test, but have to wait till tomorrow...

I have a (German) SCL011 "Generic Contactless Reader" for USB. Is there a way to edit NTAG213 on Windows PC using it? NFC21 tool does not support this reader, otherwise I suppose it could work?

I do not know how to make such a program. Is there an open source solution for Arduino + PN532?

Hi,
first post and a few questions, if I may.
So I haven't even bought a 3D printer yet, but the Mini W is looking like it tops my list.
So, like others that have either already bought, or are thinking of buying the Mini, it's just a little off-putting that the cost of legit XYZ spools cost so much, and I'd definitely be interested in a reliable alternative solution.
But it seems that the cost of all the tools required to hack the spools also comes into play. Bearing in mind I have an iPhone, so the android phone isn't an option, looks like I'd need to buy all of the following :
1..EMUTAG - approx. £40 + cell batteries
2..Arduino Uno (I already have one of those)
3..Adafruit PN532 - approx. £40, but Chinese clone can be had for £10
4..an ebay purchase that gives me something software wise or other (a password?) :-) $5 / £8 ??

I need the EMUTAG to replace the NFC card in the spool, and I need the Arduino and PN532 to be able to program it.

So once I have that all working I'd be able to purchase any reel of PLA and fool the Mini into thinking I am using a genuine XYZ spool. So the main question is - is the Mini really worth this hassle, or would putting the cost of the Mini, approx. £230, together with the extra cost of the above parts, make it really worth buying a different make printer that does not require a proprietary spool??
Also to consider is the cost of XYZ spools compared to others, in the UK - are the other really much cheaper and/or better quality?

Apologies if this first post and question is in the wrong place - MODs feel free to put it in a more appropriate place if necessary.
Cheers,
Texy

Texyuk, I did exactly what you described.  Bought the red PN532, had an Arduino nano, bought the software from the eBay guy , designed and made a case and put it all together.  I will do what I need, but it is not a complete package.
I wish I just bought the complete solution from. Cgrillo / bozotheclown.

Do yourself a favor and purchase it from these guys.

Hi cgrillo, thanks for the reply and info.
So regarding this £20 option that replaces items 2 and 3 in my list, I already have an Uno, and in my haste last night, I ordered the red PN532 clone already. So I'll need the software, which I believe is the .net application that you/bozot have written, and the arduino script?
And also a EMUTAG....
I see you are in the UK - can you recommend a good PLA source/type/supplier that works well with the Mini?
cheers
Texy
