Help!

A few suggestions.
In 'movement'
Use homing order with a pre heat option as this allows you to specify the X Y coords to home Z and also raise Z before probing.

#define HOMING_ORDER HOME_ORDER_XYTZ
#define ZHOME_X_POS 0
#define ZHOME_Y_POS 0

Also set pre raise so that Z is raised befor homing X Y

#define ZHOME_PRE_RAISE 2
#define ZHOME_PRE_RAISE_DISTANCE 5

In 'Z Probing'
Increase the switching distance to make sure probe untriggers

#define Z_PROBE_SWITCHING_DISTANCE 5

Set the Z_Probe height to a realistic value or you will drive the nozzle into the bed

#define Z_PROBE_HEIGHT 1.2


Hope this helps.

OK! Where to start.

What are you using for a the Z-Axis probe/end-stop
#define ENDSTOP_Z_MIN_INVERTING true
#define MIN_HARDWARE_ENDSTOP_Z true

You may need to invert the end stop signal, Test to see if the signal changes when active - M119 (Get End-stop Status)
