HMS 0300-9100-0001-0003: chamber heater over-temperature
HMS 0300-9100-0001-0003 means the chamber heater ran over temperature and protected itself. Airflow first, then the sensor that told it the chamber was cold.
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 0300-2D00-0001-0006: heatbed levelling failed
HMS 0300-2D00-0001-0006 means bed levelling failed and asks you to clear debris. What actually blocks a mesh, and when the plate itself is the problem.
HMS 0300-2500-0001-0008: nozzle touches the heated bed abnormally
HMS 0300-2500-0001-0008 means a nozzle is touching the bed harder than expected. Debris under the plate comes first, then the nozzle, then the levelling.
HMS 0300-1A00-0002-0001: the nozzle is wrapped with filament
HMS 0300-1A00-0002-0001 means filament has wrapped around the nozzle. How to remove it without damaging the silicone sock, and why it keeps happening.
HMS 0300-1800-0001-000B: nozzle presence detection failed
HMS 0300-1800-0001-000B means the printer cannot detect a nozzle. Either it is genuinely missing, or it is seated a fraction proud. How to check both.
HMS 0300-1800-0001-0007: eddy current sensor frequency too high
HMS 0300-1800-0001-0007 means the eddy current sensor frequency is too high, which points at a damaged sensor or at a nozzle that is not there at all.
HMS 0300-1800-0001-0002: eddy current sensor sensitivity low
HMS 0300-1800-0001-0002 means the eddy current sensor reads weakly, usually because the nozzle is not fully seated. How to refit it before blaming the sensor.
HMS 0300-1E00-0001-0007: left nozzle temperature sensor open circuit
HMS 0300-1E00-0001-0007 means the left nozzle temperature sensor reads as disconnected. On a dual-nozzle machine, which half is affected and what still prints.
HMS 0300-0200-0001-000B: right nozzle temperature control abnormal
HMS 0300-0200-0001-000B means temperature control on the right nozzle has gone abnormal. How to test the heater and the sensor before ordering a hotend.
HMS 0300-0200-0001-0008: nozzle cannot reach the set temperature
HMS 0300-0200-0001-0008 means the nozzle cannot reach its set temperature. A draught, a tired heater or a loose connector, and how to tell them apart.
