EBB36 wrong temperature measurement

Hello,

I’m having low temperature reading with several different temperature sensors, every time the reading is 15-17 degree lower than the bed or beacon temperature. Tried with 4 pieces of generic 3950 and one EPCOS 100K B57560G104F sensor, at 23 degrees the Generic 3950 is reading 5 degrees, the EPCOS 100K B57560G104F is reading 8 degrees, what could be the issue?

Thanks!
Andy

This board has a jumper on it to switch between a 4.7k pullup resistor for thermistors, and a 2.2k pullup for PT1000 sensors. If you’re using a thermistor, make sure this jumper is not installed, and the sensor is configured in Klipper for a 4.7k pullup.
