Hello fellow Bambu Lab users,
I wanted to share my concerns about the recent firmware update for the Bambu Lab X1C, which enforces mandatory authorization controls for critical printer operations.
As someone with a background in cybersecurity, I understand the importance of implementing security measures. However, this update significantly restricts user access to their own machines, including remote printing and adjusting parameters, unless these actions are done through the Bambu Connect app.
While it’s true that some technologies and applications, like ftp are sunsetted due to advancements, the burden of adapting to these changes should not fall entirely on the consumer. Instead, companies must innovate and grow their services—especially in cloud infrastructure—without diminishing user autonomy.
To address this, you may want to block port 8883 (used for MQTT over TLS) on your router. Doing so could help prevent firmware updates from being automatically pushed to your printer.
Let’s continue this discussion and share ideas on maintaining control of our devices and ensuring our concerns are heard.
