Bambu Lab firmware restricts third-party control of its 3D printers

Bambu Lab's authorization-control firmware makes printers accept commands only from official software, cutting off direct control for tools like OrcaSlicer. Owners can use Bambu Connect or a local-only Developer Mode, but the latter disables Bambu Cloud features.

• Firmware rejects control commands from unauthorized software while status reads still work
• Bambu Connect routes jobs through an authorized path without internet or an account
• Developer Mode opens MQTT and FTP but disables Bambu Cloud and is unsupported
• Section 7.4 of the terms allows blocking print jobs until an important update is installed
