What does "Err: MINTEMP PRINTER HALTED Please reset" mean?
"Err: MINTEMP PRINTER HALTED Please reset" is an error message you might encounter when using a 3D printer. This message indicates that the printer has detected a temperature reading below the minimum allowed value (MINTEMP) for one of its components, typically the hotend or the heated bed. This error is a safety feature to prevent potential damage to the printer or its components.
Common reasons for this error message include the following:
A disconnected or damaged thermistor: The thermistor is a temperature sensor responsible for monitoring the temperature of the hotend or the heated bed. If it's disconnected or damaged, it may send incorrect readings, causing the printer to halt.
A firmware issue: The printer's firmware might be incorrectly configured, leading to false temperature readings. You may need to update or reconfigure the firmware to fix this issue.
A hardware failure: There could be an issue with the printer's mainboard or the wiring connecting the thermistor to the mainboard.
To resolve the error, try the following steps:
Turn off the printer and unplug it from the power source.
Inspect the thermistor connections and wiring for any visible damage or loose connections. Repair or replace the thermistor if necessary.
Check the printer's firmware configuration, specifically the minimum temperature settings, and update or reconfigure the firmware if needed.
If none of these steps resolve the issue, consult your printer's documentation or reach out to the manufacturer for further assistance.
