not working, i wrote that i calibrated it many times
i enabling steppers and it starts bouncing
BUT when i disable steppers it stabilizes klippy (2).log (1.2 MB)
(i calibrated it now with steppers enabled)
when steppers are disabled it is keeping at 10-20% stable
but when steppers are enabled it is bouncing around 0%-50% quickly

You have no SAVE_CONFIG area in your klippy_log, you might have ran autotune but you didn’t run “SAVE_CONFIG” once it ran or it would have updated your printer.cfg.
PID control is just a software layer which is analyzing input behavior and driving output.
So explanation for crazy behavior is crazy behavior of your thermistor data - input.
You can try to query analog values which klipper is getting from your board and converting it to temperature by executing command
QUERY_ADC NAME=extruder
most probably you will see same crazy behavior of analog values.
You can check if it’s real hardware behavior by connecting voltmeter to your thermistor and monitor voltage behavior.
If you will confirm that it’s hardware behavior - then you need to troubleshoot hardware issues.
Possible hardware issues:
Wiring issues, unstable ADC reference voltage, unstable power supply, faulty thermistor, EMP interference.
You either have a wiring or even power issue or when it runs fine with Marlin (I guess) your Atom Terminal might not be the fastest causing erratic behavior.
yes i think there is some interference in wiring or somewhere else, is there a way to apply filter to pid control?
(also, although it bouncing a lot, it keeps the temperature pretty stable within 204-206 at 205 target )
Ok, so you understand that you have hardware issue - good.
You want to ignore it - bad.
To summarize your request: “I’m very bothered with jumping temperature graph in UI which is caused by malfunctioning hardware, can I do something so I would not see it ?”
Short answer: Yes, remove checkbox “Show chart” in fluid UI settings. - this will hide the temperature graph.
