3D printing · NFC · Flashforge
Tap a spool. The printer knows what's loaded.
I write open-source tools for Flashforge AD5X and Creator 5 printers: NFC filament tag readers, Spoolman integration and wired Ethernet. These guides show how to build them, and which parts I use.
Projects and build guides
Every project is free and open source on GitHub.
zmod_esp32-nfc
Wi-Fi NFC filament reader
An ESP32 and a PN532 make a network reader that sets your AD5X or Creator 5 slot from a spool's tag, even on stock firmware.
zmod_nfc · esp32_rfidnfc2usb_bridge
USB NFC reader for Zmod
Plug a reader into the printer. Decodes Bambu, Creality, Snapmaker, OpenSpool and more, with Spoolman matching.
C5_USBNIC
Wired Ethernet for the Creator 5 Pro
A USB gigabit adapter and a driver built for the printer's kernel. Wi-Fi stays on as a fallback.

Which NFC reader chip to buy for filament tags, and what each one can and can't read.
Buying guide
NFC tags for filament spools
Why NTAG216 stickers are a good pick, and which tag formats the readers understand.
