Thanks, I will try your table. Now I started at 110 °C just to get rid the
below zero readings at room temps, seems to oscilate at 6-10 °C at about 21 °C
room temp.
I also used complete table as adc_temperature and while readings of resistance
when heated were crazy accurate, it gave me even -200 °C (!!!)
I think Klipper is not ready for such beast thermistor. Marlin is, it gives
21-23 °C with same thermistor at room temp.
Termistor is fine, proper adc values and resistance, in Marlin it printed PLA
at 205 °C and PETG at 240 °C on all metal just fine, when dropped below 170 °C
it became quite hard to push through PLA, so it seems to be ok.

I remember needing to do some trial and error and cross referencing a few
different spec sheets from dyze, TL and electronic supply house listings to
land where I did with these. But it is working across all of my machines that
all have the same hardware.
These are on the fysetc S6 which uses the STM32F446 mcu and are mounted in
the triangle labs dragon hotends with copper blocks (mix of high and normal
flow).

Hi, I'm using Trianglelab T-D500 thermistor on my hotend. I have read issue

In Marlin, it reported temps not below 21 °C even if not heated.
In Klipper, it oscilates from -8 °C upwards when not heated. For now, to
avoid Klipper shutdown, I had set the min_temp to -10 °C.
However, I don't feel safe about this – in case it fails, there is huge
possibility Klipper will not do Thermal shutdown.
Is there a better way to set it via [verify_heater] ? I can't quite
understand options there.
