How to change pin of thermo sensor?
If there are 2 slots for temperature measurements, you don't need to solder anything, just plug the thermistor from one into the other and switch pins in the firmware. This board is basically a RAMPS 1.4 board, it includes the pins_RAMPS.h header file, so in order to switch the T0 with the T1 temperature port, you need to change:
//
// Temperature Sensors
//
#ifndef TEMP_0_PIN
  #define TEMP_0_PIN                          13  // Analog Input
#endif
#ifndef TEMP_1_PIN
  #define TEMP_1_PIN                          15  // Analog Input
#endif

to:
//
// Temperature Sensors
//
#ifndef TEMP_0_PIN
  #define TEMP_0_PIN                          15  // Analog Input
#endif
#ifndef TEMP_1_PIN
  #define TEMP_1_PIN                          13  // Analog Input
#endif
