ABL Fail Bilinear. (no replies)

Hello everyone.

I have a z-probe problem I cannot figure out. I have read all the post I could find related to my problem with no luck.

My Machine:
DIY 3d printer running the lastest release of Marlin as of this date.
Build Area: 540x 445y 500z
Hardware: SKR 1.1 Pro with TMC2209 on all except Z and extruder (TMC2208)
The machine homes at the bottom of the Z axis
DC42 Probe

When trying to ABL, get the following

G29 L20 R150 F20 B300 V3

But when I try to run it on the whole area of the bed, I get:

I have attached Config.h and Config_adv.h

I am completely lost. Please help.
