multiACE firmware is a community project — built by hobbyists, for hobbyists. Worth taking a moment before you flash:
- The project is not endorsed or supported by Snapmaker, Anycubic, or the PAXX upstream maintainers — and hasn't been verified by them either.
- Running custom firmware may affect your manufacturer warranty. Snapmaker support generally cannot help with a modified printer.
- As with any firmware flash, an interrupted process can leave the printer in a state you'd need SSH access or a stock image to recover from. Rare in practice, but worth knowing.
- This software comes without warranty — formally covered by GPL-3.0 §15–17. Translation: I do my best, but the responsibility for using it stays with you.
If any of that doesn't sit right, no worries — the Snapmaker stock firmware and the official PAXX builds remain available. If you're on board: have fun, and feedback / issues are always welcome.
