Ahhh, interesting. That’s good to know. Thanks for chiming in!
Might be late to the party, but maybe others are interested, as I’ve ended up in this place as well.
I’ve solved the issue by adding the following line to the Extruder chapter in printer.cfg.
pullup_resistor: 10000
This value of 10000 fixed the 30deg C difference between nozzle and thermistor reading on my Rapido hotend. And works for different temperatures equally well.
Btw, has the world gone nuts? Based on the previous “answers” here, I have to think yes …
