I bought a ntc thermistor and soldered it, but the thermistor shows the wrong value, I wonder where the error, can i change the marlin to t0 pin t2
Value is always 52 °C

You can try different thermistor lookup tables or create your own if you've got a reliable temperature probe, ie a thermocouple with an accuracy of around 2 degrees c.

But if the reading is fixed at that value, even though you hold the thermister in your hand you may have a wtong value or broken thermistor. It could point to a broken arc input port. Swapping pins may help.
