Introduction to the HMS

The Health Management System (HMS) is resposible for the monitoring and alerting of the printing system which includes: 

 

 Hardware connections (How the system is connected) 

 Issues with the physical hardware (Fans, Hotend, Heatbed) 

 Motion system (Belts, rods) 

 Printing issues picked up by AI (First Layer Scanning and Spagetti Detection) 

 

 If an abnormal status is detected the HMS will alert the user to the issue and if required, provide a QR Code to further information from the Bambu Labs Wiki

 Error Code ID 

 The ID of the HMS Alert 

 HMS Workflow 

 The HMS is a system of sensors monitored by the central management unit. The below is a simple diagram to show how it works. 

 

 Error Code 

 For each alert the HMS dispays a unique error code for it. For example, if there is an error with the heatbed temperature the code is 03000100010001. This error code can be searched on the Bambu Lab WIKI 

 Notification 

 When the HMS dectects an abnormality the printer takes actions based on the severity of the alarm; Warning status messages will show in the printer's LCD, whilst fatal errors will provide a popup message window on the printer's display and request for you to select an action. 

 The HMS will also send a notification message to Bambu Handy and Bambu Studio if connected to the printer 

 If the HMS detects that something is wrong in the system, it will provide the error message along with the error code on the screen. The notification method for each message is different, based on the level of severity. For fatal errors, it will pop up a message window on the machine's display and request user confirmation. For warning statuses, the HMS will just show a notification message on the right of the display screen. The HMS will also send a notification message to the mobile app.  

 Limitations 

 The HMS has some limitations as it is not able to cover all potential failures, due to: 

 

 The HMS can not evaluate all failure modes of the printer as it does not have sensors to collect that data 

 Some errors can not be identified directly such as lost steps. 

 The HMS is not designed to find root causes of issues. For example a failed first layer may be caused by a number of reasons, such as incorrect flow rate, printing to fast. The HMS can only detect that it is possibly failed 

 

 Using the HMS 

 You can utilise the notifications from the HMS to keep an eye on the system including some mechanical and hardware errors, as well as for troubleshooting when some issues occur that have caused the printing to fail. Bambu Labs have a wiki page and an howto for each error code and what to troubleshoot. If you are unable to resolve the error yourself, Bambu Labs offer after sales support via a support portal. The support portal can be accessed from the main Bambu Labs website 

 If a critical alert occurs it will put a dialogue message on the screen asking for you to take an action 

 

 The HMS messages can be found on the printer by clicking on the Assistant button at the bottom right of the screen. 

 

 This will then display any error messages on the screen
