@knuxvomica no they don´t.
Current state: G28 homing failed , and nothing happens
Before with a homez.g: The axis lifts 5mm, moves down then passes! the endstops and hits my frame when I don´t emergency stop...
As you can see I am using the M564 command to test the axis movements in advance (which works fine) but obviously I don´t have any homing , i.e. no printing possibleM564 H0 ;move without homing
Please post your full config.g
Homing Z should be as simple as a G1 H1 Z move to move the z axis such that the endstops are hit.
You need G1 H1 Z-700 at the end of your homeall.g to home the Z axis. The same would be needed in homez.g
