Error MINTEMP / MAXTEMP

The “MINTEMP” or “MAXTEMP” error on a 3D printer is associated with extruder temperature issues. Here’s what you can do to fix this:

STEP 1: CHECK THE RJ45 CONNECTOR

  • Check that the extruder’s power RJ45 connector is properly connected to the extruder. Make sure it is well inserted and that there are no loose joints or faulty connections.

STEP 2: RESTART THE PRINTER

  • After checking and, if necessary, replacing the RJ45 connector, restart the printer. This will allow the system to perform a new control on the extruder temperature.

STEP 3: CHECK THE TEMPERATURE OF THE EXTRUDER

  • When heating the extruder, check that the temperature gradually increases and reaches the desired value without error. If you notice that the temperature is not reached or fluctuates significantly, there may be a problem with the extruder’s temperature sensor or heater.

STEP 4: CONTACT TECHNICAL SUPPORT

  • If, despite the attempts described above, the error persists, it is recommended that you contact Technical Support as you need a more thorough diagnosis to determine the specific cause and resolve the issue.
