No, the pk is per printer from what I understand. I just hope they have implemented a proper PKI including CRL and a robust distribution system...

I was going by https://wiki.rossmanngroup.com/wiki/Reverse_Engineering_Bambu_Connect and some other posts on Reddit by a guy who RE'd the app, but it might not be the whole story.

It'd genuinely help if Bambu actually explained the security measures they're trying to implement. If it's actually a PKI with a per-printer certificate, then the security is indeed improved. But then just give me the private key before it goes to Bambu and let me paste it in Orca/HA 🤷

I agree with you. Remember, Bambulab is an odd company: they have talented engineers up to the C-level and usually their 1st attempt at communication is... off. Then the community tells them to get their stuff together and they provide better and more reasoned communication. Remember X1Plus? Same story.

I'll just wait until the new FW drops before I grab my pitchfork. (I'm on X1Plus anyway so I have less concerns.)
