bed pid tune strange
so i wanted to do a pid tune of the bed just to be sure
M303 P1 S100
it goes to 100 with no issue, i get
but the temp climbs to 108 and in the end i get a timeout
what could be the reason for this? the firmware can see that the temp is above 100 but yet it keeps heating (led flash very fast)

You could test with 90°C and see if it does converge in that case. Guess the algorithm has some limitations on what it can work with.
are there any "hidden" parameters i can change to go higher?
replaced it 2 months ago
i tried 90 and temp was hovering at arround 65
60 still works
