Dolly Clone - Hotend wrong temperature

Hi folks, I am trying to get my Dolly clone up and running, but no combination of settings under the 1.1.0 RC8 used for Dolly are allowing the hotend temperature to read accurately. Can anyone advise? all temperatures are 100+ degrees, or negative values.

wrong thermistor choosen in firmware or broken

I have tried two different V6 hotends and both return the same values. I have also tried all hotend values throughout the firmware, results are below. First number is Temperature as standard, second is the temperature with the 4.7k (4.4k) resistors between hotend and ramps.

 * Temperature sensors available:
 *
 *    -3 : thermocouple with MAX31855 (only for sensor 0)

Just to advise, I did manage to fix the issue. In the end I bought a pack of 10 thermistors from amazon, a bench test proved they were giving the correct readings, so I had to remove the original thermistor from the hotend, and replace with one from Amazon. It now heats and works correctly!

…Now just to sort out the rest of my issues!
