Hotend temp dropping way under room temp

My P1S just had a clog after printing TPU and after I unclogged it the printer would say it was at 18C for a moment then slowly drop down to zero. I’m sure it isn’t the thermistor as I have replaced it twice and I checked the cable connections and they seem fine.

I am having the exact opposite issue minus the clog part. Mine is incredibly high and wont go lower

I ended up fixing my problem ( I accidentally damaged the fpc cable while clearing the clog) but it sounds like your problem could be the thermistor

That would do it.


Take a look at the post I made. It goes into a ton more detail onto what’s happening.
