hi
I would like to install a firmware on my ender 3 v2 that has no termal runaway but I can’t get it to compile. Can someone help me with this or better send a compiled firmware
I would suggest asking in 3D printing forums, e.g. Creality, Marlin, etc which will be more specific this here. Marlin requires recompilation for configuration and there are several HOWTO on the net . For example, this one (which may or may not fit your Ender version Compiling Marlin 2.0 for Ender3 v2 - NotEnoughTech
BTW, you mentioned that you want to disable thermal runaway, I hope that you know what you are doing, since this is an important safety feature.
