You have a problem following instruction too. Please include Configuration files as requested.
This is just a guess, but you seem to assume that your bed uses PID controlled heating.
However, in the config you posted, #define PIDTEMPBED
is commented out.
I had this problem too and found this issue. With the conclusion @chgi found, I guessed I just have to do an PID-Tuning after my Update to Marlin 2.0.5.3. and now it works. Thanks @chgi and thanks to @diego0078 . I can only hope this helps for you too.
I solved this problem by resetting eeprom. On 60C it stop on 50.4C. And pid calibration over 10 rounds
I'm not sure if this is related but, for some reason the code is made to limit max-heating to be -15° below max.
So if you in configuration.h for example set:
The actual max temp would be 275°C.
See line 599 in Marlin/src/gcode/bedlevel/G26.cpp _if (!WITHIN(g26_hotend_temp, 165, (HEATER_0MAXTEMP - 15))) {
and line 46 in Marlin/src/gcode/lcd/M145.cpp _ui.preheat_hotend_temp[material] = constrain(v, EXTRUDE_MINTEMP, HEATER_0_MAXTEMP - 15);_
...and a bunch of other places.
Not sure what the purpose is to have a configuration.h saying one thing, and having code doing something else.
Above HEATER_0_MAXTEMP you get a MAXTEMP_ERROR including a stopped machine. Because our heaters always overshoot the target temperature it needs a margin to avoid that.
Thanks, that make sense in a way. It would be nice though if the configuration.h mentioned this. It took me a couple of days extra to figure out why I couldn't get even close to the default 275°C.

Hi. I have problém with heating bed If i set some temp heating stop 10 degree leds for example set 60c hotbed stop heating 50 c But If i try calibrate PID heating is ok Please help Marlin firmware 2.0.4 Skr 1.3
