Think I have figured out what you mean!!

// Use "Z Safe Homing" to avoid homing with a Z probe outside the bed area.

// With this feature enabled:
//
// - Allow Z homing only after X and Y homing AND stepper drivers still enabled.
// - If stepper drivers time out, it will need X and Y homing again before Z homing.
// - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28).
// - Prevent Z homing when the Z probe is outside bed area.
//#define Z_SAFE_HOMING
#if ENABLED(Z_SAFE_HOMING)
#define Z_SAFE_HOMING_X_POINT ((X_MIN_POS + X_MAX_POS) / 2) // X point for Z homing when homing all axis (G28).
#define Z_SAFE_HOMING_Y_POINT ((Y_MIN_POS + Y_MAX_POS) / 2) // Y point for Z homing when homing all axis (G28).
#endif

#define HOMING_FEEDRATE_Z (2*1000)
718 set to 0_0
Line 737,738 puts the bed center at half the max X,Y ( / 2 ) print area?
Just need to uncomment line 734 //#define Z_SAFE_HOMING?
OR do I need to use the
//#define MANUAL_X_HOME_POS 0
//#define MANUAL_Y_HOME_POS 0
//#define MANUAL_Z_HOME_POS 0 // Distance between the nozzle to printbed after homing?
All this may have been related to the problem I had getting it to print in the center of the bed a while ago.
Please do correct me if I'm wrong (prob am) as this is still a BIG learning curve for me.
