G28 homing is in the wrong direction. about fablin

[marco-fabteam]

it works again by changing Configuration.h line 347 #define EXTERNAL_Z_ENDSTOP_INVERTING true to false. Both the endstop hit AND the g28 behaviour are solved.

Basically with EXTERNAL_Z_ENDSTOP_INVERTING true to false set to false you can do normal homing and movement. But when you add the probe hardware to thesecure_sw port the behaviour is the same as before.

the opposite happens if you set EXTERNAL_Z_ENDSTOP_INVERTING to true:
with the probe it works correctly, without it does not!

Note that if you run a g28 and it hits the z_max endstop it will somehow fix the port status back to normal in both cases.
Another option is to have EXTERNAL_Z_ENDSTOP_INVERTING set to false and set it to true once the functionality has been enabled via gcode (M746 S1 sets it to true, M741 S0 sets it to false).
