And I have tested the TP100 resistance value and TP100 of TEMP1 has a resistance of 4.8k ohms.The rest is normal. I have a question, now that I have changed the pins, the temperature value is obtained from TP100 of TEMP2, why does it still appear to restart automatically.

Thank you for your guidance, I have made the new changes exactly as you suggested. However, after restarting the machine, there is still a problem with the heating. Specifically, when the temperature reaches about 180C, the machine automatically restarts, as shown in this video.

The problem i met is mentioned in my previous topic. Because of the D12 in board i thought may be some problem occur in HEARTER1 or temp sensor 1. Thaks for your advice, i will check the resistance of PT100 as soon.

Thanks for your reply! Actually i have made the following attempts, 1. modify the configuration.h in folder Marlin from https://github.com/Ultimaker/Ultimaker2Marlin #define TEMP_SENSOR_0 20 #define TEMP_SENSOR_1 0 #define TEMP_SENSOR_2 0 #define TEMP_SENSOR_BED 20 #define MAX_REDUNDANT_TEMP_SENSOR_DIFF 10 change to #define TEMP_SENSOR_0 0 #define TEMP_SENSOR_1 20 #define TEMP_SENSOR_2 0 #define TEMP_SENSOR_BED 20 //#define MAX_REDUNDANT_TEMP_SENSOR_DIFF 10 2. modify the temperature.h in folder Marlin from https://github.com/Ultimaker/Ultimaker2Marlin replace all HEATER_0 in temperature.h to HEATER_1. After completing the above operation，the machine runs fine. But the temp sensor value in LCD is wrong. The temperature of sensor is always 489c. After that, i do some new changesas following: 1. modify the thermistortables.h in in folder Marlin from https://github.com/Ultimaker/Ultimaker2Marlin exchange the HEATER_0 with the HEATER_1 and then i verified the marllin project in Arduino IDE successfully, but when i upload to board, Error-stopped temp sensor coccured.

My board is Ultiboard v2.0, single nozzle. The temp sensor1 interface seems to be broken. Now I want to connect the TP100 to the temp sensor2 , heating wire to the heater2, and the Extruder to the E2 interface. How should I modify the Marlin firmware?

When I heated the print head, the machine shut down suddenly. I checked the PCB board and found that when the nozzle temperature is increased, the D12 red light will flash. Do I need to replace it with a new IRF8736PBF MOSFET?
