Hi, I like your g-code.

In section "Build plate detection", on line 203 you write: Runs ONLY when "Bed Leveling" is enabled
Do you mean "Bed Detection" or the resonance test should be in the "Bed Leveling" section?

@maniq2 Is your version ready for general use, or are you still testing ?

My version is without AMS and sound. I have done many prints with it without default. There is still an error message on the printer, same for the version with AMS and sound.

Ahh I see, I have starred your gist. Will use when error gets fixed. Thanks for the update though .. i also want to use without AMS and sound.
EDIT: Cant find your fork now.
