There’s an encrypted key generated by Bambu that is valid for one year. The guy who has decompiled Bambu Connect has demonstrated that. The current key was generated (if I recall correctly) sometime between 12 and 15 December 2024, and it’s valid until 12 to 15 December 2025. If the printer doesn’t receive a new key by then (that means you have to connect to Bambu’s cloud), it would lock itself out (not accepting anymore commands) and your printer becomes a permanent and expensive decoration in your house/workshop… that’s according to the same person who did the decompiling.
See for yourself
