Note that LCD controller and Cura agree on motion direction. + and - of each axis works equally well in the LCD and in OSE Lulzbot Cura. LCD control is relative from the 0 point.
Note that if cables are crossed, some steppers work with crossed cables (where order of certain pairs is reversed) - while other steppers do not. This indicates that the internal wiring of the steppers differs between steppers.

Homing

X and Y home well
Z moves down and stops. Huh? Never seen this before. Z stop triggered without z probe connected?

< Reporting endstop status < x_min: open < y_max: open < z_min: TRIGGERED

Issue - Z probe - I have LJ18A3-8-Z/BY-5V. Is BX recommended? What is the difference? [1]. See Instructables article.
Switching the power pins does not allow probe to trigger. Green is the outermost connection - that is assumed signal, middle is ground, red is power. I reversed ground and power
In configuration.h, I set #define Z_MIN_PROBE_ENDSTOP_INVERTING from false to true. No change in behavior - it is normally closed, not normally open
Trying #define Z_MIN_ENDSTOP_INVERTING true - changing it to false. It worked.
I left Z_MIN_PROBE_ENDSTOP_INVERTING at falso - so I changed only 1 thing.
