When the nozzle temperature is lower than the minimum extrusion temperature set in the firmware, possible reasons include:
Hotend damage, resulting in inability to reach the set extrusion temperature. You can check other related hotend heating error handling methods.
Extrusion temperature set below the machine's configured minimum temperature. Creality OS has a minimum extrusion temperature limit of 170°C. Using incompatible slicing settings may cause temperature issues.
Slicing compatibility issue: Confirm if the extrusion temperature setting is above 170°C, and use official slicing software or contact official support for correct third-party slicing configuration files.
Hotend failure: Check if the hotend is damaged or malfunctioning, replace it if necessary.
Check the current extrusion temperature setting, ensure it is above 170°C before performing the extrusion.
Use officially recommended slicing software or configuration files for slicing.
Check if the hotend is working properly, repair or replace if necessary.
