Error messages

There are a few error messages that could show up while using your Ultimaker Original+. If you ever happen to get one of these errors, you can easily follow the instructions below to troubleshoot the issue.

Make sure to always turn the Ultimaker Original+ off and disconnect the power supply before troubleshooting these errors.

Mintemp or Maxtemp error

This refers to a problem with the PT100 B sensor, which is the sensor that measures the temperature of the nozzle. It means that the sensor registers incorrect values and due to safety reasons it will prevent the nozzle from heating up. If you get a MINTEMP error the Ultimaker Original+ registers a too low temperature (< 5°C), while a MAXTEMP error suggests a too high temperature (> 300°C). The most likely reason for this is connection problem, which could either happen due to a bad connection at the main board or damage of the sensor itself.

To check if there is a bad connection on the main board you will have to take a look at the bottom of the Ultimaker Original+:

  • Place the Ultimaker Original+ on its side so you can reach the bottom side and remove the wooden electronics cover.
  • Now you will see the main board. Look for the sensor cable (the white cable with three thin red and white/grey wires at the end), which is connected to 'TEMP1'.
  • Make sure the cable is connected and check if none of the thin wires has come loose.

Still not working? This probably means that the sensor itself is damaged. To verify this you could measure the resistance with a multimeter. It usually should be approximately 108 Ohm at room temperature, but when it is broken the result will either be (close to) 0 or infinite. This means that a new sensor needs to be placed on your Ultimaker Original+.

Mintemp or Maxtemp error bed

This error refers to a problem with the sensor of the heated bed. It means that the sensor registers incorrect values and due to safety reasons it will prevent the heated bed from heating up. If you get a MINTEMP error BED the Ultimaker Original+ registers a too low temperature, while a MAXTEMP error BED suggests a too high temperature. The most likely reason for this is connection problem, which could happen due to a bad connection on the heated bed or main board, or damage of the sensor itself.

The connections at the heated bed can easily be verified by checking if the sensor wires are well secured. These are the two thin wires connected to the screw terminal at the back of the heated bed. Gently pull them to see if none of the wires is loose. If one of them is loose you will have to remove the heated bed so you can reconnect the wires.

To check if there is a bad connection on the main board you will have to take a look at the bottom of the Ultimaker Original+:

  • Place the Ultimaker Original+ on its side so you can reach the bottom side and remove the wooden electronics cover.
  • Now you will see the main board. Look for the heated bed sensor cable, which is the one connected to 'TEMP3' and check if it is properly connected.

Still not working? This probably means that the heated bed sensor is damaged or that there is a bad connection on the heated bed itself. In order to resolve this issue we recommend replacing the heated bed. You can get in touch with our support department for checking the possibility of sending you a new heated bed under warranty.

Heating failed

The heating failed message means that the Ultimaker Original+ is unable to heat up the nozzle. When you get this error message you will probably have a flashing UltiController display as well.

The reason for this heating problem is most likely a bad connection. Therefore you need to take a look at the heater cartridge cables; they are connected to 'HEATER1' on the main board. It is advised to take them out and reconnect them in order to be sure about a proper connection.

If the error still appears after having checked the connections, it could mean that the heater cartridge itself is damaged. Our support team would be more than happy to give further assistance.
