I have problem with the Ultimaker Original Thermocouple sensor.
First the temperature showed in cura was "operational temperature: 0". I tried all the best unplug and plug in the wire to the port on the board but the result did not change. So, I decided to remove the couple from the heating unit to see what wrong in there. I found the mesh jacket a little tear off. Then I try to pull out the sensor a little from the metal cover, then the ceramic came out broken into pieces.
Did I do something wrong? How can I fix this?
Thanks a lot for your kind advice.
