Hello,
I've been printing with my Ultimaker for a while and everything was fine, i printed some good stuff and there were almost no problems. A while ago my temperature sensor started to act strange, when i set the temperature to 230 the temperature was just rising till 230 and when i pressed print the kept changing from around 220 to around 240 (I used cura and pronterface to see the temperature) and it did not print. For some reason the temperature kept rising though and my PEEK insulator started to smoke and molt apart. I got a new PEEK insulator and temperature sensor, the weird temperature problem hasn't stopped yet and i can't print with Pronterface anymore. Cura also gives the changing temperature and will only print if i restart the printing interface around 5 times. I made some screenshots so you can see the problem:

I can still print but it takes a very long time to start it with Cura, any help would be very appreciated.
Thanks in advance
