Description
I finally was able to get an SKR 1.4T & Exp-Mot working together.
My Config is a CoreXY with 4 Z Motors and The New BugFix 2.X Marlin.
Marlin 2.0.7.2 does not work with the exp-mot, unless you want to manually customize it yourself.
open Pins_BTT_SKR_common.h
Remove the "//" from the line //#define HAS_BTT_EXP_MOT 1
in Configuration_adv.h I changed #define NUM_Z_STEPPER_DRIVERS 2 to #define NUM_Z_STEPPER_DRIVERS 4
I had errors while compiling at this point "You can't use both an LCD and a Motor Expansion Module on EXP1/EXP2 at the same time."
I had to Disable "//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
Then everything worked for me.
I hope this helps people.

Research direction
Read the configuration steps in issue #14, including Pins_BTT_SKR_common.h and Configuration_adv.h, and compare them with the stated Marlin 2.0.7.2 setup. The issue does not request a specific change; any documentation work would need to make the SKR 1.4T and Exp-Mot configuration and LCD limitation clear and verifiable.
