Operator facing machine:
X homed= +0 to left side, right arrow move it to right, DRO always +....
Y homed= +0 toward operator, up arrow moves it away from operator, DRO always +....
Z homed all up=+0, DRO changes from +...to -.... when moving.
Two Limit Swt. on each axis.
I suspect Home can be relocated.

Thanks
