HMS 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 status of the system, 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.
The relevant Wiki page content for the A1 mini is still being built. Thank you for your patience.
This HMS code page is under construction. The information shown here may not be complete or up-to-date from time to time.
This page is about the codes produced by Bambu Lab Health Monitoring System.
When the printer encounter an issues during initializing, calibration or printing, it can pop up an HMS code for further diagnosis. Here is some further info for each HMS code:
