Hi all,
I noticed today that when the K8200 is unplugged, my thermistors read as normal (20k multimeter setting, ohms), however when the printer is plugged in both report back around -14ohms.
I doubt this is correct - any ideas?

You cant measure resistance when there is voltage present.
Yep, i already replied him that on another thread…
The only thing you CAN do is measure the voltage on the pins and compare them to your temp reading.
5v is around 0°C and 0.42V should be around 200°C with thermistor table for thermistor type 5.
