PT1000 Thermistor setup.

Trying to understand using a PT1000 Thermistor but between the RatOS install guide and the EBB36 V1.2 manual. I am conflicted on if I should be using the same pins as the standard NTC104 thermistor or the ones connected to the MAX 31865 chip.
Solution:
Use the standard 2p thermistor port. Then in user overrides in printer.cfg do:
[extruder]
sensor_type: PT1000
[extruder]
sensor_type: PT1000
...

I recommend putting in the PT1000 jumper (see the ebb manual) for increased accuracy, and then it's this:
[extruder]
sensor_type: PT1000
pullup_resistor: 2200
[extruder]
sensor_type: PT1000
pullup_resistor: 2200

MAX31685 really only makes sense for PT100 and you'd be very hard pressed to find a practical difference between the two

So I just had the Pullup resistance wrong. 2200 vs 4700... BTT doing things weird again. Well now that Beacon and Dragon UHF are installed and hopefully working well... I won't need to mess with Klipper again for a while after tuning again. Thanks again @miklschmidt
