This fork was created for the implementation of the new TwoTrees Sapphire Plus revision with unsynced Z-Axis drives and dual Endstops. Therefore new precompiler-dirctives have been added to the configuration.h and !configuration_adv.h!
It will also include preconfigurations for the E3D Hemera mounted with this mount (Seems to work best on dual endstop-revs). I remixed the mount for the useage of an EBM Pabst RLF35. See Thingiverse
