Bambu Lab AI Spaghetti Failure Mid Print

A 'spaghetti' failure occurs when extruded filament fails to adhere to the build plate or the model, resulting in a tangled mass of plastic. The Bambu Lab printer utilizes its chamber camera and internal Neural Processing Unit (NPU) to monitor for this specific defect. When the AI confidence threshold is met, the printer triggers error code 03008003 or HMS notification 0C00_0300_0003_0008. This diagnostic state indicates that the printer has identified a structural failure, typically caused by poor bed adhesion, collapsed support structures, or nozzle collisions, and has paused the print to prevent further material waste or hardware damage.
