HMS (Health Management System) is a function set up to facilitate the users of the Bambu Lab printer and AMS to troubleshoot the issues. The users can take advantage of notifications from HMS to know the system's status, including some mechanical and hardware errors, or the reason for printing failures. We've set up a wiki page with a detailed description and troubleshooting for each error code. Therefore, when you see the message prompted by HMS, you can scan the QR code with your mobile phone to go to the corresponding page to check the cause of the fault and the troubleshooting steps.
