¶ Issue Description
After the chamber temperature is set, the system will begin natural cooling or active heating until the target temperature is reached. If the sensor detects that the chamber temperature still hasn't reached the desired value after a period of adjustment, this reminder will appear.

¶ Troubleshooting
¶ Tools, Equipment and Materials
None
¶ Solutions
¶ Case 1: Error during chamber cooling
It may be that the temperature of the heatbed is set too high, causing the chamber temperature to be baked to a high level and difficult to cool naturally, or the external ambient temperature is too high. If the gas in the chamber is non-toxic, you can open the front door and the top glass cover to help cool it down, or appropriately lower the temperature of the heatbed.
¶ Case 2: Error during chamber heating
- The printer chamber may be poorly sealed. Please check whether the printer's front glass door and top glass cover are tightly closed, and whether the top automatic vent and active chamber exhaust are closed normally. If there is an external exhaust fan on the back of the printer, please confirm whether the exhaust fan is turned off to prevent the hot air in the chamber from being continuously extracted.
- The chamber temperature sensor may be installed abnormally or blocked. Please check the chamber temperature sensor above the printer's front glass door to ensure that the sensor extends about 10mm and is not blocked by foreign objects such as the FPC cable of the birdseye camera.
¶ Equivalent Codes
The following HMS codes represent the same type of issue.
| HMS Code | Description |
|---|---|
| 0300-9400-0002-0003 | Chamber failed to reach the desired temperature. The machine will stop waiting for the chamber temperature. |
| 0300-9000-0001-0002 | Chamber heating failed. Possible causes: the chamber is not fully enclosed, ambient temperature is too low, or the power supply heat dissipation vent is blocked. |
