Slice thermistors
Stupid question? What is a "Slice thermistor" - Is this an extra thermistor I should purchase for my Duet 3?
On my existing printer running Repetier I have one thermistor for the hotend and one for the heated bed.
It's a high temperature thermistor intended for hot ends, made by Slice Engineering, https://www.sliceengineering.com/shop/high-temp-thermistor. So it does the same job as a standard hot end thermistor, except it can go to higher temperatures.
Unfortunately, the high resistance at low temperatures of this and other high temperature thermistors make them difficult to read at low temperatures when using the ADCs built into microcontrollers. We could make a daughter board with a precision ADC on it to better read these thermistors, but we already have other high-temperature options such as PT100, thermocouple, and PT1000 (which requires no daughter board).
