The filament control is entirely optional. It allows you to set up some macros to help automate a load/unload process or to have specific settings for different materials/processes. That can be whatever you need it to be, but it is optional.
@deckingman@jay_s_uk a few days ago i've tuned my hotend using dual 60W heaters. actually i got "not recommended" tuning value. after that i can heat my hotend without getting any fault, but right now when i heat my hotend it just turn out to fault because temperature not reached. i decide to tuning my hot end again, but it turns out "auto tune cancelled because target temperature was not reached".
any solution? thanks
