V6 Thermistor Table for Repetier Firmware Update

I’ve been trying to get my V6 working properly with my Boxzy printhead for about 2 weeks now and finally figured out (I hope) where the problem lies. My firmware doesn’t have a Thermistortable listed for the Semitec GT2 in the Extruder.cpp and has a defined user_thermistortable0 listed in the configuration.h file that it is referencing whether I change the thermistortype from 5 to 8 or not. This is not covered in your update instructions at all (surprised/not surprised). The closest thing I could find to a replacement table was here:

https://reprap.org/wiki/Thermistor#ATC_S...

but it seems pretty lacking, plus I have no idea how any of these numbers correlate to 0 C, something I need to know since the Boxzy uses the temp reading to determine what tool head I have in place. pertinent sections of my config file below. I really need these answers, please.

Well, I've already taken care of it and got it up and running. And then two days later the amplifier board for the PT100 I got from you guys showed up so I installed that and my printer isn't running again. Followed y'all's instructions to the T, continuity tests out fine on the wiring, firmware verifies and uploads and then I open the GUI (Repetier type)and this is what I get in the log before I even connect to the printer - 16:05:30.169 : ImportPlugin:Could not load file or assembly 'CncPlugin, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.
