I’m not familiar with the 3D printing space, but seems like this reverse engineering was inspired by the companies move to clamp down on security of these devices. [1]

From what I understand, this new auth system would make third party integrations (ie, “OrcaSlicer”) obsolete and users would be limited to controlling the device via Bambu Connect. This update impacts users who control the device via HomeAssistant and “print farm management” users. I guess first party support for users with fleets of these printers is dogshit, thus the need for third party software.

Seems after 3 days of community feedback/outrage, the company is backtracking on the Bambu Connect only route. Instead offering a “Developer Mode” option in firmware which on the surface seems to be what the impacted users need. [2]

> In response, we’ve made the decision to implement an optional LAN mode feature, to provide advanced users with more control and flexibility.

> Standard Mode (Default): By default, LAN mode will include an authorization process that ensures robust security

> Developer Mode (Optional): For advanced users of the X1, P1, A1, and A1 Mini who prefer full control over their network security, an option will be available to leave the MQTT channel, live stream, and FTP open. This feature must be manually enabled on the printer, and users who select this option will assume full responsibility for securing their local network environment. Please note that Bambu Lab will not be able to provide customer support for this mode, as the communication protocols are not officially supported.

Seems this resolves the community concerns. Or am I missing something?
