So I just found out why my Ultimaker temp measurements are off. Turns out some idiot thought referencing the ADC to USB +5V was a good idea.

Typical arduino coder: why use the built-in accurate voltage reference when you can use USB VBUS? Yeah, let's do that.

Well, it does make sense when you just use an NTC and a resistor as voltage divider on the VUSB rail.

But certainly not when you're using a thermocouple and a preamp chip with absolute output.
