Hello
i have a corexy with a rumba borad and i've uograded the power supply from 12v to 24v. the heating bed work correctly but i have some issues with the hotends: during the autotune the temperature of the hotend raise too quickly and it go beyond the set point then the board send the message :Autotune failed temperature too high.
I've tried to lower pid_max factor till 64 and then the autotune works but after that the hot-end can't reach high value like 260.
What do you think? Could i have some suggestions?
Greetings
