When I startup my Ultimaker it default temperature is 50 degrees. This causes bad extrusion of course.

Do I need to buy a new temp sensor? or is something else wrong?

 

Thanks

Does any one know, Is it the temp sensor or the motherboard?

I guess it is the temp sensor, but it can be changed easily.

The temp sensor in your Ultimaker2 is a PT100, I guess it may be defect or the connector is not properly seated.

 

You can check the temperature sensor with a ohm meter. The resistance at room temp (20c) should be around 108 ohm. See linked table.

 

You can measure by taking the TEMP1 connector off the mainboard (see picture, sorry Ultimaker took the first picture I found and it was an aliexpress clone 🙂 )

 You can get a replacement part at any ultimaker reseller, for example;

The connector was not correctly connected any more. So it was a simple fix.

It measured 109 ohm.

Thanks again for the help
