I have a 3d printer with skr v1.4, but when I turn on the machine, I get maxtemp error at startup, the same problem does not occur when I unplug the thermistor cable, how can I solve this problem?
"Sounds like a thermistor open circuit. It should read low resistance"
it seems to me that if it was an open circuit, it would change nothing when thermistor was unplugged.
i would check for a short in the thermistor or its cables

I agree. Most thermistors are about 100,000 ohms at around room temperature. They DECREASE in resistance as they get HOTTER. The printer is saying it's already too hot (low resistance), so there is a short in the thermistor or its wiring.
