After rebuilding my Orca with Arduino/Ramps (I fried my Gen6) I can't get the temp higher than 226 - 228 degrees.
It heats up at 100% until 226, than it goes to zero power, shoots over to 228 after which it drops to 226 after which power comes back on at 90%
Than it shift between 226 and 228 continuously with power zero and 90%
But my Host says 240....... and my max temp in the deck says 260, so what parameter s still faulty ? Any idea ? My ConfigH is included

Can you make a screenshot of temp. graph zoom = 5min, checked every second. Since you are using dead time control your dead time ( P parameter) might be to high for your extruder, so it stops too early. From settings I see no reason to stop earlier.

See graph.
This run is with new PID values, after a PID auto-tune session.
PID is now : 14.58 / 1.12 / 49.28
However, setting is 240 and realization is around 223

You haven't zoomed the temp. to 5 minutes, so it is a bit hard to see. In this scale it looks like your temperatures are jumping quite a bit. That is a big problem with such a high damping.
Maybe you should first start with simple bang-bang to see how a natural swing looks like for that extruder and if it reached target temperatue. It is the most simple logic which turns heater on until target is reached. So if that works we know how it swings from the graph and can switch to the complicated controllers like dead time or pid.

Thanks for helping out,
What is bang bang ?
Maybe a parameter in the code ?
My config.h code is attached.....

It is one of the possible temperature controls like PID and dead time you can select:
Heat manager:
0 = Bang Bang, fast update
1 = PID controlled
2 = Bang Bang, limited check every HEATED_BED_SET_INTERVAL. Use this with relay-driven beds to save life time
3 = dead time control
You can set it in the eeproms by setting the corresponding number.
