ReSpool — Support

ReSpool writes the NFC tags that Anycubic ACE 3D printers read to identify filament, so third-party spools are recognised like Anycubic's own.

Common questions

The app says my tag cannot be written. Anycubic's own tags are password-locked at the factory and cannot be reused. Use a blank NTAG213 sticker (or larger) — a few pence each online.
Nothing happens when I hold a tag to the phone. Hold the top edge of the iPhone flat against the tag and keep it still until the scan sheet confirms. Cases thicker than a few millimetres can block NFC.
The printer does not recognise the tag. Scan the tag with the app first to check what is on it. Every write is verified byte for byte, so a tag that scans correctly holds exactly what was written.
Something went wrong mid-write. A full backup is taken before any write, under Library → Backups. Scan the tag again and restore the backup if needed — nothing is lost.
How does the Home Assistant integration fit in? Every tag carries a unique spool ID, which the hass-anycubic_cloud integration reads so identical reels can be told apart.
