I'm trying to read temperature of the heated bed with a 100k thermistor bought trough ebay. I can not read a correct value on pronterface. I tried whit another 100k thermistor and a 10k NTC too and almost every "configuration.h" thermistor table. No one works for me. When 1k pull ups were used, a fixed value of 20 - 40 C were measured but if the heated bed is turned on, that value never changes.
The connection is correct and the thermistor resistance is OK.
