¶ Issue Description
The touch screen or the Fluidd shows the error message during printing:
Please run 'SDCARD RESET FILE' or 'FIRMWARE RESTART' to resume.!! Extrude below minimum temp.
¶ Reasons
-
Incorrect settings of the slicing software. Printing with the nozzle temperature set below 170℃ is not supported.
-
Damaged thermistor of the extruder.
¶ Troubleshooting Steps
¶ Tools needed for troubleshooting
-
2.0 mm Allen key
-
2.5 mm Allen key
-
Multimeter
¶ Step 1 Print the model saved in the USB Flash Drive for testing
The USB flash drive test file is sliced with the default settings of ELEGOO Slicer or ELEGOO Cura.
If the file in the USB flash drive is deleted, you can find it on our official website.

If the issue still occurs when printing the test file, refer to Step 3 for further troubleshooting.
-
If the issue does not occur when printing the test file, refer to Step 2 for further troubleshooting.
¶ Step 2 Re-slice the model with ELEGOO Slicer or ELEGOO Cura
- Download ELEGOO Cura or ELEGOO Slicer from the following websites.
ELEGOO Cura download link: https://github.com/ELEGOO-Slicer/ELEGOO-Cura4.8.0/releases/tag/4.8.0_1.1.1.0
ELEGOO Slicer download link: https://github.com/ELEGOO-3D/ElegooSlicer/releases

-
Install ELEGOO Cura or ELEGOO Slicer.
-
Load the model to be printed into ELEGOO Cura or ELEGOO Slicer, re-slice the model with the default settings, and then upload the .gcode file to the printer.
¶ Step 3 Check if the extruder thermistor is damaged
-
Turn the power switch OFF (symbol "◯") and unplug the power cord.
-
Loosen the three screws of the rear fan assembly with a 2.5 mm Allen key and remove the rear fan assembly.
-
Remove the four screws securing the back side of the extruder with a 2.0 mm Allen key.
-
Remove the two screws securing the front side of the extruder.
-
Remove the extruder and re-plug the thermistor plug.
-
Check if the extruder thermistor is damaged.
-
If a multimeter is available, check whether the resistance value of the thermistor is within a reasonable range. The resistance value of the thermistor used for the extruder is usually about 100kΩ.
Note: The thermistor specification used for Neptune 4 and Neptune 4 Pro is NTC100K high-temperature resistant 300℃ thermistor (φ3*10-L85mm) with 2Pin PH2.0 terminal.
- If the thermistor wire is damaged or the resistance value of the thermistor is out of the reasonable range, the thermistor needs to be replaced.
