Submission + - Cloud Glitch Causes 3D Printers To Start On Their Own, Spooking Owners (techspot.com) 1
Many owners of Bambu 3D printers recently awoke to find completed print jobs that they hadn't initiated, ruined print jobs, or damaged printers. The company has already determined the source of the problem and is implementing software revisions so users no longer fear that their 3D printers might have become haunted or self-aware. Bambu's investigation revealed that on the night of August 15, an MQTT SDK client timeout caused an outage in the cloud infrastructure that handles remote 3D printing jobs. Amid two disconnections, cloud-connected printers queued and initiated printing while the owners were sleeping.
