      hi, not to sure on this

      do you have to isolate the thermocouple from touching the metal on the hot end block. I saw something in setup talking about isolating the thermocouple from the hot end and I am not sure what they meant or how to achieve this.

          Yes. You can get mineral-insulated cartridge-type thermocouples that are already insulated.

              Look up its specification to see whether the thermocouple tip is insulated from the housing. Or check using a multimeter.
