The resistor for heating should be fine. Does your firmware not support changing thermistor profiles?

Never tried it. Firmware is Sailfish.

Doesn’t list anything like that.

I’ll check into that …at some point.
Too busy even to think of setting up a build environment on a Mac to compile a firmware for the Thing-o-Matic mainboard and one for the extruder-controller board.
