HMS 0500-0600-0002-0001: toolhead camera not in place
HMS 0500-0600-0002-0001 means the toolhead camera is not in place. It is a seating problem far more often than a dead camera. Where to look, and in what order.
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 0500-0100-0002-0002: Live View camera not connected
HMS 0500-0100-0002-0002 means the Live View camera is not connected. The ribbon at the toolhead is the usual cause, and printing continues without it.
HMS 0300-C100-0001-0001: adaptive airflow cannot enter cooling mode
HMS 0300-C100-0001-0001 means the adaptive airflow system cannot reach cooling mode. The air door is the first thing to check, and it is usually mechanical.
HMS 0300-9100-0001-0008: chamber heater control abnormal, vent blocked
HMS 0300-9100-0001-0008 means the chamber heater tripped its over-temperature protection, usually because the left vent is blocked. What to clear, in order.
HMS 0300-3200-0001-0001: right-side auxiliary fan slow or stopped
HMS 0300-3200-0001-0001 means the right-side auxiliary fan is slow or stopped. Debris and a loose connector come first, and the fan itself is the last resort.
HMS 0300-1800-0001-000C: eddy current sensor signal jump
HMS 0300-1800-0001-000C means the eddy current sensor signal is jumping. Poor contact at the toolhead comes before a failed sensor. How to check it properly.
HMS 0300-1600-0001-0001: extruder servo current sensor abnormal
HMS 0300-1600-0001-0001 is a current sensor fault on the extruder motor. How to tell a sampling circuit failure from a motor that is genuinely dragging.
HMS 0300-1300-0001-0001: Motor-A current sensor abnormal
HMS 0300-1300-0001-0001 is a current sensor fault on Motor-A, which is a board problem rather than a motor one. How to prove it before you replace anything.
HMS 0300-1200-0002-0001: toolhead front cover fell off
HMS 0300-1200-0002-0001 means the toolhead front cover has come off. Why the printer stops for a plastic cover, and which replacement fits your machine.
HMS 0300-0F00-0001-0001: abnormal accelerometer data
HMS 0300-0F00-0001-0001 reports abnormal accelerometer data. A restart clears most cases; when it does not, the toolhead cable is the suspect, not the sensor.
