I want to implement auto bed leveling using one of thesehttps://9apps.ooo/
my first question is,
to upgrade to Marlin 1.1.9, can i just download it from the marlin website, substitute the example configuration.h from the Geeetech folder and upload it?
I could not find a definitive post on here with Geeetechs own 1.1.9 download.
