Error Log

The error log collects all errors and HMS alerts (Health, Maintenance, Safety) from your printers. 3DPrintForge has a built-in database of 268 HMS codes for Bambu Lab printers.

HMS codes

Bambu Lab printers send HMS codes via MQTT when something is wrong. 3DPrintForge automatically translates these into readable error messages:

Code	Example	Category
0700 0100 0001 0001	Nozzle heatbreak clogged	Nozzle/extruder
0700 0200 0002 0001	AMS filament stuck	AMS
0700 0300 0003 0001	Bed leveling failed	Build plate
0700 0500 0001 0001	MC disconnect	Electronics

The complete list covers all 268 known codes for X1C, P1S, P1P, A1, and A1 Mini.

Severity levels

Errors are classified into four levels:

Level	Color	Description
Critical	Red	Requires immediate action — print stopped
High	Orange	Should be addressed quickly — print may continue
Medium	Yellow	Should be investigated — no immediate danger
Info	Blue	Informational message, no action needed
