Height Incorrect, strange movements with SKR 1.3 + Marlin 2.0

by lazzer010

I have a SKR v1.3 installed into my Predator running Marlin bugfix-2.0.x . When I run delta auto-calibration the printer's height gets set to 471.8, way above the 455 it should be. The probe z-offset is set to -16.8, so it looks like marlin is subtracting the probe offset from the height. This can't be right since I can't get a proper z=0 to be level with the bed.

However, running a G29 to auto-level the bed makes the height 454.71, pretty close to printable and I can actually get some plastic on the bed if I babystep it. But, during a print the nozzle doesn't move correctly on the X & Y axis. It move diagonally up on the Z. Like, if it should be at X=0, Y=10 Z=0 it ends up at something like X=0, Y=7, Z=2.

There just doesn't seem to be any pattern and after three days I'm really running out of ideas. Any help would be greatly appreciated.

I included my marlin configuration file. Thank you!
