HMS 0300-C200-0001-0002: Hall sensor of the filter switch flap
HMS 0300-C200-0001-0002 means the Hall sensor on the filter switch flap is not reporting. Check the wiring before you decide that the sensor has failed.
Category: Error codes
Machine error codes explained: Bambu HMS codes, MINTEMP and MAXTEMP, thermal runaway, homing and probe failures. What the code means, and what to check first.
HMS 0300-C000-0001-0002: filter switch flap air door malfunction
HMS 0300-C000-0001-0002 means the filter switch flap is stuck. What that flap does for the filtration path, and how to free it without breaking its linkage.
HMS 0300-C000-0001-0001: chamber temperature switching flap failed
HMS 0300-C000-0001-0001 means the chamber temperature switching flap will not move. It is nearly always mechanical, and usually something in the path.
HMS 0300-A200-0001-0001: MC module temperature too high
HMS 0300-A200-0001-0001 means the MC board is running too hot, usually because the chamber is hot and its fan is not keeping up. What to check, in order.
HMS 0300-9100-0001-000A: chamber heater 1 abnormal, AC board suspect
HMS 0300-9100-0001-000A points at chamber heater 1 and possibly the AC board. What you can safely test at home, and what is a service job for somebody else.
HMS 0300-9000-0001-0010: chamber temperature controller communication abnormal
HMS 0300-9000-0001-0010 means the chamber temperature controller has stopped answering. A restart first, then the cable that carries the link over to it.
HMS 0300-2E00-0003-0001: motor noise cancellation needs recalibrating
HMS 0300-2E00-0003-0001 asks you to recalibrate motor noise cancellation. It is a routine request after a firmware update, not a fault to repair at all.
HMS 0300-2800-0001-0004: cutting module force sensor abnormal
HMS 0300-2800-0001-0004 means the cutting module force sensor is not reporting. A disconnected cable comes before a failed sensor here, every single time.
HMS 0300-2700-0001-0004: nozzle offset calibration sensor abnormal
HMS 0300-2700-0001-0004 means the nozzle offset calibration sensor is reading oddly. On a dual-nozzle machine this is what keeps the two tips aligned.
HMS 0300-2600-0001-000B: left nozzle presence detection failed
HMS 0300-2600-0001-000B means the left nozzle is not detected. Either it is missing, or it sits a fraction proud of its seat. How to check both properly.
