Comparison of Type 1 thermistor and E3D thermocouple temperature measurements

[printbus]

Back to the drawing board. The data presented in the original post is flawed and pretty much useless.

Overnight, I realized the AD595/AD597 thermocouple measurement approach has an error component that the thermistor approach wouldn't have. This morning, I determined the error on my printer would cause the thermocouple measurement readings to be low by about 6%, or about 15 degrees at a setpoint of 250 degrees. That goes a LONG ways to explaining the discrepancy between the thermocouple and thermistor measurements.

The original post has been expanded with an interpretation of the test data that discusses this new found issue. I'll have to repeat the entire test, and I'll have to see when I can block the bank of time aside for it. Throughout the hours it takes to do the test, I'll be reminded how I'm not so enamored with AD595/AD597 temperature measurements using the MEGA2560 board.
