I am becoming crazy solving HE temp problem
Suddenly my heater going fault. ( temperature rise too slowly)
I changed the thermistor and heating cartridge with an identical model but the problem remains the same.
I connected an extra thermometer to the hot end and what I see is that the temperature, in reality, reaches 260 but the printer thermometer stops around 196 and doesn't go further.
During cold down the external thermometer register, a fasted drop-down of the temperature than the printer thermometer.
Any idea what could be wrong. The problem arised suddenly after a regular switch off the printer

Try to make a PID-Tuning...
@claustro Please provide some information. Send M115 and post reply. Post config.g. What thermistor are you using?
thank you for answering me. The problem arised suddenly so I don't think a config problem.
The thermistor is semitec 104gt-2 , is the same I always use with this printer
I tried to make a pid tuning but it stops because it can reach the set temperature, maybe I can try to make a pid tuning at 180 instead of at 200 for one time.

This is the string suggested the seller where I bought the thermistor.
I can try to change it .
@claustro, does the temperature read correctly when the hot end is cold, i.e. room temperature?

Yes it is correct.
This problem occurred before. I dismantle the HE changed thermistor and cartridge many times and without a clear reason ti starts working again correctly , till yesterday
@claustro You could try autotuning the thermistor ADCs: https://duet3d.dozuki.com/Wiki/Calibrating_thermistor_and_PT1000_readings
You'll have to use the 'Manual calibration' on Duet 2 WiFi.
I made a pid tuning at 190 degree instead of 240.
changhed the m305 as suggested.
Seems ok for now , let's see.
Thank you all
