Hey guys I just got a Da Vinci Mini w+ and ran into the issue with my spool running "empty" because I used third party filaments. I didn't realize this was going to be an issue until both xyzprint and the third party software MiniMover(Cura won't work for some reason) both won't let me print. I read some of the other topics on this forum and saw that you can essentially reset the NFC chip with an android or an Arduino. I only have an iPhone and was wondering if that would work as well, because all of the apps I see on the apps store seem to run differently. I'm really trying not to spend anymore money including on buying an arduino because I'm on a tight budget. Any help would be greatly appriecated.

You can buy an old cheap android phone of ebay for less than $50 bucks. You can also use an old Android Tablet.

Did you ever come up with a solution? I'm having the same issue now. I bought ntag213 tags and the printer is saying the serial number have been used already for the filament....

Did you use the app and let it set a different serial number? You can't reuse a serial  number once it has been in the machine rather it was empty or partial.
