Problem enabling Z Home Safe

Does anyone know why I'm getting this error (static assertion failed: Z_SAFE_HOMING_X_POINT is outside the probe region.) when I try to enable Z_HOME_SAFE feature. I'm using Marlin 1.1.9 and an MKS Gen 1.4. Print area is 220mm x 220mm x 240mm.
Thanks

What did you set your Probe offset from extruder configurations too?

This is what I have it set to.
#define X_PROBE_OFFSET_FROM_EXTRUDER 0 // X offset: -left +right [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER 20 // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER 1 // Z offset: -below +above [the nozzle]

And your Z-Safe homing config look like this.

#define X_BED_SIZE 220
#define Y_BED_SIZE 220

// Travel limits (mm) after homing, corresponding to endstop positions.
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define X_MAX_POS X_BED_SIZE
#define Y_MAX_POS Y_BED_SIZE
#define Z_MAX_POS 240


#define Z_SAFE_HOMING

#if ENABLED(Z_SAFE_HOMING)
#define Z_SAFE_HOMING_X_POINT ((X_BED_SIZE) / 2) // X point for Z homing when homing all axes (G28).
#define Z_SAFE_HOMING_Y_POINT ((Y_BED_SIZE) / 2) // Y point for Z homing when homing all axes (G28).
#endif

Clif, I wanted to thank you for your help. I just copied a new configuration.h file and only configured the minimum to get rid of that error. Now every time I apply power to the control board I get a driver error. This has been the craziest thing. Every time I get one thing fixed something else breaks.

Upload your configuration.h and configuration_adv.h to a google drive, copy the shareable link'

Post shareable link and will take a look see what is going on for you.

Hey Clif, here is the link to the files you requested. Also, I found that the wiring was causing the driver error but now that is fixed the drive won't enable so they still don't move.

Never done bed leveling the way you are doing it

Found a link for you to look at
[github.com]

I added the following boundaries and the code did compile

// Set the // Set the boundaries for probing (where the probe can reach).
#define LEFT_PROBE_BED_POSITION 10
#define RIGHT_PROBE_BED_POSITION 210
#define FRONT_PROBE_BED_POSITION 30
#define BACK_PROBE_BED_POSITION 190


// The Z probe minimum outer margin (to validate G29 parameters).
#define MIN_PROBE_EDGE 10

I believe the Boundaries are required to use Z Safe Homing

Got it, I will give it a try tomorrow when I have time to make the changes and test it. Thank you for the guidance and help.

I made the changes that you suggested and I got it to compile with no errors. Now when I try to print I find that the motors are enabling. To be honest I'm on the verge of trashing this thing.
