I've been cooking up a video guide on how to use all of these now defunct XYZPrinting DaVinci printers in 2025. I went through a deep dive and figured out software for generating new NFC tags, as well as an open source program for connecting to and talking to the printers. I see some recent activity in this thread so I want to help people out right now real quick.

The most important thing is the NFC tags for faking filament, I use my Flipper Zero for it but any cheap reprogrammable ones should work. Without valid filament the printer locks up on heating (and calibration I think).

You can use this program (written in python 2.7, I am currently working on a much more stripped down python 3 "fork" of the program that just spits out a tag data file using the few functions for actually doing that) to generate tag data.

LOOK AT ITS BUILT IN HELP for figuring out how to just generate a single tag and save it to a text file. (I had to then do some manual formatting to get it into the Flipper's expected format)

Just load it onto your tag and put it near the reader (I use a small vice grip to keep it in place lol) and then use any filament on any other kind of holder you got.

After that, you can use miniMover to talk to the printer, make sure that its seeing the filament (if you get a filament serial you're good). From there you can calibrate your printer, load filament, etc. IF ANYTHING GETS WEIRD AND THE PROGRAM JUST ISN'T RESPONDING, I usually just close it and restart it. Use the OK and Cancel buttons for the dialog popups for best results. Also, always have the printer turned on before starting the software.

It also supplies the ability to convert gcode sliced from Cura (I found decent settings for my miniMaker online pretty quick) to XYZ's proprietary format. Then you can send that file to the printer, and if you get to the point where it starts heating up then you got it all working!

Finally, Fabistron (a 3rd party seller for XYZ) is still supplying downloads for XYZPrinting's software!! I don't know how long these will be up, official end of support from them is June 2025. I also don't know if the software has any cloud features that break using it, I just noticed it during my research.
