Describe the bug I have recently upgraded my MK3S+ printer with the MK3.5 upgrade. I print a LOT of PLA plaques with a good amount or ironing. When I was first starting out I encountered heat creep on about every plaque I was printing, somewhat consistently, clicking sounds after about 5-6hrs of prining. During such prints the extruder motor was getting very hot eventually resulting in the Bondtech gear heating up too much, softening the PLA to the point of it not getting pushed through, hence filament grinding and the dreaded clicking sounds. I have then discovered the solution, ECOOL mode inside the experimental features menu. This resolved my issues and I have forgotten about ever having these problems. Now, after happily upgrading to MK3.5, and being amazed at the improved speed of my prints, I once again encountering the dreaded clicking sounds. Please, fix this regression and port the ECOOL mode to the MK3.5 firmware. I'm not printing with a closed enclosure, I have even tried adding an additional fan on top of the extruder which possibly delayed the heat creep but did not solve it like ECOOL did. I would hate to have to go back to my old MK3S+ setup.
How to reproduce Go to hardware menu, hold the knob for experimental menu, and try to find the ECOOL mode. It is not there :,(
Expected behavior Go to hardware menu, hold the knob for experimental menu, find the ECOOL mode, turn it on and happily go on with your life without worrying about heat creep and the dreaded clicking sounds.
