Yeah, makes sense based on where the sensor is, my heater didn’t have a thermocouple on it so I drilled a hole for a thermistor midplate, it’s super slow to respond is the downside but in theory it should be accurate enough.

I don’t have experience with the bambu, in theory everything will experience thermal expansion but for the voron setup, the bimetallic construction is some of the issue, they have different thermal expansion properties so it can cause deflections.
