Android App for resetting/writing blank ntags (Page 10 of 20)

Did you download the APK from the very first post?

Is your phone actually NFC capable? Just being an Android phone does not make it capable. Some don't have NFC hardware.

I used the RFID NFC Tool download.  I found a video online and followed it.  It showed on the amount all 9's for how much filament is left.  My phone is a Galazy S5.

I did everything in the instructions and now i get an error message
"Cartridge cannot be recognized, replace with Genuine xyzprinting cartridge"
did i put one of the values in wrong?

ok where would I enter the random serial number?  Where do I get that from?
This is what I have done see the attachment

WTF.  It took me longer to download the app then it did to update the tag.  I ran it and it is working great.  Thanks a lot for your help.  This is awesome.

I have a samsung galaxy S5 running 6.0.1.
Like I said it worked faster then I thought.  Thanks again.

The Davinci hotend will be damaged if you go higher than stock temps.

Yesterday, I got my hands on an official reel of the PETG from XYZ. The chip in it appeared to make the printer print at about 220-225. When I used the official XYZ Print software, and set the temperature to +10 degrees (the highest it will let you go), my printer started printing at about 235.

Here's a picture of my printer at those temperatures using nothing but the tools XYZ offers.

I'd say, for the Davinci Jr at least, that 235 is the upper end of the stock temperatures right now.

For the person who wrote this app, here is the data from the reel that goes to 220-225. http://www.soliforum.com/post/149481/#p149481

Well, the NFC card does set it at 220-225. It was only after I told the program to add 10 degrees that it got that hot.

But if you look around at different brands of PETG, you can find some that say 210 to 240°C and others that say 230°C - 260°C. I would guess it's more about the specific composition of those PETG filaments and maybe even their colors. I printed a couple of Benchys on the printer last night using the MG Chemicals PETG. It did terribly at 220, but did much better at 235.

Hi, I am still checking possibilities. Have a Junior 1.0 Wireless unit with upgraded version. It was 2.3.6 version and I tried to downgrade it so I could use reset tags from original spools.
So I used tag reset app and was able to reset tag to 200m but it became unrecognisable by the printer.
Then i tried to downgrade firmware to version 2.2.4. Screen prompted that ir was successful. And when checked again with pc application, could see that firmware version has changed, BUT printer screen was still displaying previous, higher version and reset tag wasn't recognised. Then on PC i used prompt to Upgrade firmware from Internet and successfully did it. New firmware version displayed on the printer is 2.4.5 and guess what! Previously reset tag became recognised. It is showing 200m now. But when scanned with NFC reader it shows Extruder temp 93 degree and Heathed bed (which i don't have) - 212 degree. And I can't reset the tag anymore.
Any ideas of what's happening and how to reset tag to proper temps?
Thank you

The temp is set by the color. But to my knowledge once a tag has been allowed to go to zero the machine will remember that tag and not allow it to be used or reset again. You have to get paper tags and program a new one. On that tag the extruder and bed temps are swapped.

I was able to use this spool with reset tag successfully.
Despite Android app showing tepm set to 93°, extruder heating to required temp for yellow filament, that tag was originally programed to.
I didn't empty the spool before reseting the tag, so it is still accepted by the printer (junior wireless) and it's firmware version is 2.4.5
Spool had about 8 meters of PLA left on it and after tag was reset to 200m I successfully printed two small objects.
So all went good
