PT1000 thermistor EBB42
Not able to boot into RatOS using an Octopus 1.1/EBB42 1.2, have a PT1000 connected to the toolboard and getting ADC out of range errors on the heating.
Added the following into my printer overrides, and put the jumper on the PT1000 pins on the EBB42 for TH0. I've tried this code with and without the sensor_pin line commented and it doesn't seem to make a difference, wondering if I might have a broken thermistor or if there could be a different problem.
#PT1000
[extruder]
sensor_type: PT1000
#sensor_pin: toolboard:PA3
pullup_resistor: 2200

remove the line pullup_resistor
Same issue
Maybe It s broken
Remove also the jumper,no Need it
Yeah thinking it might be broken, plugged it into the Octopus and same issue, so I ordered a new one will test when it gets here
any update on this having exactly the same problem. Does anyone know the resistance values at room temp for the P1000?

This was solved; thermistor was broken
FYI I've confirmed this as well. With the thermistor in TH0 on the V1.2 EBB42 board, I required the sensor_type: PT1000 and pullup_resistor: 2200 to be set. If I didn't set the pullup resistor then it gives a ADC out of range fatal error. I have the TH0 jumper installed. Also, I exported my klipper.log beforehand and no existing pullup_resistor value was defined. Perhaps it should be added to the board/btt-ebb42-12 toolboard config?
