In the spirit of science I am trying one change at a time. I connected the thermistor to the second input on the Daughter board and changed the firmware accordingly, I did not add the additional 2 wires. The temperature seems to be about right now as it prints nicely at 225 degrees. I suppose this indicates your suggestion that the converter chip is faulty. How do I go about fixing it as I will need the second channel soon once I have all the initial bugs worked out and add a second extruder?

Well thank you all for your help. With dc42 suggestion and Link to wiring diagram from T3P3Tony I have it fixed. I had the black and blue crossed. (So much for making black the standard ground or negative).
All is working as it should.

Cheers everyone.
