iPhone
Write NFC spool tags for the Anycubic ACE, see what is left on every reel via Home Assistant, and tag Prusament-style OpenPrintTag spools.
ReSpool writes the NFC tag that Anycubic ACE 3D printers read to identify filament.
Anycubic only sells spools with these tags, so filament from any other brand is invisible to the printer. ReSpool writes a blank NFC sticker with the material, colour and printing temperatures of whatever spool you actually have, and the printer then recognises it like its own.
WORKS WITH HOME ASSISTANT
Every tag gets a unique spool ID, carried in the SKU. The hass-anycubic_cloud integration reads it from the Anycubic cloud, so Home Assistant can tell two identical reels apart and track how much filament is left on each. Connect the app to Home Assistant and the Library shows what is left on every reel, straight from what the printer has extruded.
THE WHOLE ANYCUBIC RANGE
A catalogue of more than 600 genuine Anycubic product codes ships with the app and works offline — every colour of every line, with temperatures taken from scans of real spools. Pick a product and write it straight to a tag, or scan a genuine spool to add it for everyone.
OPENPRINTTAG TOO
Read and write Prusa's open standard, as shipped on every Prusament spool, on ICODE SLIX2 tags. OpenTag3D and OpenSpool are supported as well.
HONEST ABOUT WHAT IS LEFT
Put a part-used reel on the scales and the app works out the filament left, writes that to the tag, and can update it later on the same tag — same spool ID, same history. Photograph a spool to pick up its colour.
TWO TAGS PER REEL
The ACE reads one face of the reel. Write a second sticker for the other side carrying the same spool ID, so the reel is recognised either way up and Home Assistant still sees one spool.
SAFE BY DESIGN
- Only the data pages are ever written; the UID, lock bits and configuration pages are unreachable
- A full backup is taken before a single byte is written, and can be restored
- Every page is read back and compared byte for byte
- A tag already holding spool data stops and asks first
- Pages that already hold the right bytes are skipped
Needs blank NTAG213 stickers (or larger); Anycubic's own tags are password-locked and cannot be reused. OpenPrintTag needs an ICODE SLIX2. Requires an iPhone 7 or later.
