There are two options to get minimum temperature error on the Composer.

  • In standby mode, when you see temperature -242 С° on one of the extruders
  • During printing, when you get MINTEMP trigger error

This error comes, when Composer get temperature from one of the extruders (Heater_ID) less than 10 C°

To identify the cause of the error, you need to check the temperature sensor. Operating procedure will be:

  1. Turn off the printer
  2. Remove the protective cover from the print head
  3. Disable flat cables
  4. Measure the resistance at the defined connectors.

If the measured resistance is close to the correct (0.4-1 Om), it’s means that the temperature sensor works good. You will need to contact your local distributor or write us on
