The Bambu Lab Bus Cable 4-pin is the official replacement data cable used to connect Bambu Lab devices - such as AMS units and printers - within the Bambu Lab communication bus. It ensures a stable data link between connected units, which is essential for correct AMS operation, filament status reporting, and automated multi-material print workflows.

As a genuine OEM part, it is built to the exact specification of the original cable for a direct drop-in replacement when the original is lost or damaged. Using the official cable avoids communication errors that can occur with generic alternatives.
