Topic: Thermistor is not reading correct temperature for heated bed
Hello Soliforum community,
I am very new at 3d Printing and I am seeking more experienced help. I know your time is valuable and I am super grateful for any help you can give to help me solve my problem.
I have built a Cartesian 3d Printer, it has:
- 2 extruders
- Heated bed (16x16 in)
- Azteeg X3 Pro board
- Viki LCD Screen
- 100K ohm NTC 3950-1% Thermistor
- 85Amp power supply
Arduino Settings:
Board: Arduino Mega or Mega 2560
Processor: ATMega 2560 (Mega 2560)
Programmer: Atmel STK500 development board
I have tried both Repetier and Marlin Firmware and using Repetier Host to communicate with my board. After many hours and a new computer I finally configured everything correctly and it is connected without any errors... BUT, I cannot get the heated bed thermistor to give me a correct temperature reading.
I have connected heated bed, stepper motors, extruders, power supply all according to its correct specs and diagrams provided by manufactures. Everything is working perfectly except my heated bed thermistor. I have also tried configuring with every possible option given by both Repetier and Marlin, but still do not get a proper reading.
This is how I have my configuration.h files are set up:
#define TEMP_SENSOR_0 -1
#define TEMP_SENSOR_1 -1
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1I have checked over 30 times the correct pins (Azteeg X3 Pro pins http://files.panucatt.com/datasheets/x3 … _reva.pdf) I think they are correct, but I am open to any suggestions.

I am happy to post pictures if needed. I will upload the configuration.h files for your viewing.
Have a great day and thank you in advance for hearing me out.
Thanks !
