Homing to a Max Endstop (no replies)

Made a Custom Printer, MKS Gen L 2,0 board. Marlin 1.1.9

Using BL Touch. BL is on the LEFT side of the hotend housing. Can't home to X MIN (left side) because BL Touch.

Moved bump stop to the right side of the X 2020 V slot boom. The right side is of course X MAX.
Moved Bumpstop plug to the XMAX socket on the MKS GenL

Marlin Setting changes:
changed home direction to 1 as per Marlin Comments.
#define X_HOME_DIR 1

commented out:
//#define USE_XMIN_PLUG // disabled

uncommented:
#define USE_XMAX_PLUG // enabled

double checked that my XMAX pullup inverting was TRUE, as it is a standard NO bump stop.

Here is what is happening.
X motor will now, under no condition move in the positive direction. It tries. you hear a click, see a tiny jerk, and no movement. with a X offset of -30, i can move manually with the LCD X into the negative direction,.. CLOSER to ZERO. also known as right to left. But under no instance can i move the motor left to right or positive direction. Even if I move the motor to the full -30 direction. If I command it to move back to zero. nothing. Click jerk, no movement. Already checked board /motors /cables.

It is almost like the logic is being constantly updated to no matter where X comes to rest, it is being reset back to XMAX_POS. (X BEDSIZE 400) which would nullify any command to allow it to move in the positive direction. Because you can't move past the end.

Thoughts?
