Verify thermistor rating
We need to verify what the Pt100 thermistor is rated to.
We currently have firmware set to 450c
E3D's website claims up to 400c: https://e3d-online.com/pt100-temperature-sensor
Tyler - @Karrad with the thermocouple for the FLUKE which isn't super accurate, I measured 385C when the target is 400C and (4% off) and 430C when the target is 450C (5% off) so it seems to be a difference of ~1% error between 400C and 450C
