Hi, i have skr 1.3. I decided make a heated bed my printer. Everything is done but something wrong my board. Firstly doesn’t have heated bed settings on my LCD then i change bed termistor code 0 to 1 in configiration.h. I read 120degrees without NTC and if i plug it it change little bit. I measured thermistor connector on board. It has 3 thermistor connector and two of them has 3.3v and my failed connector has 1.6v?. Also i try to measured thermistor resistor on board, my failure connector’s resistor must be 4.7k but resistor is different value on borad(I pull up this and its give 4.7k). So i can’t use heated bed.
What is going wrong and what can i do?
Note: NTC is 100k 3590 and 125k on 20 degrees
