Marlin 2.0.x Z axis not homing to MAX endstop with G28 etc

HI Everyone,
Im setting up a new printer with Marlin 2.0.x on a Azteeg X5 GT from Panucatt and 32bit
Im having a problem with Z homing to max endstop.

What ive found so far:
Physical endstop is triggered in the max when moving bed up to endstop, this is confirmed by M119
Reset board, and M114 to return:
Recv: X:0.00 Y:250.00 Z:0.00 E:0.00 Count X:0 Y:25000 Z:0
I can move the bed down via controls on octoprint say 10mm and M114 returns
Recv: X:0.00 Y:250.00 Z:-10.00 E:0.00 Count X:0 Y:25000 Z:-10667
and then back up to 0 at MAX with the endstop triggered with M119.

Then If I home via G28 or Z axis on octoprint.
The bed keeps lowering to the min and rams into floor....?? Does not home to MAX?

Can anyone see an error or possibly know a solution. Configuration.h attached as file
cheers

My settings are all correct for:

What happens when you set:
#define Z_HOME_DIR -1

Assuming you are using an Hbot or corexy. The bed still homes to Zmin btw. It just moves up instead of down.

If the bed moves to zmax it means the bed would move down. If you home to zmin it would move up

Yes Concurr,
Just came to the same conclusion and BOOM works well.
Thanks for your help.
