This is a IR receiver and iam guessing that the orientation is crucial because it is a kind of transistor.
The green box is on the side where the box is drawn (if i compare it to mine).

What does you home gcodes consist off because you need to add some parameters when you want to move axis before they are homed.
If you want to move a axis before homing you need to add S2 to the move G1.

Example:
; Lift Z
G1 Z10 F6000 S2
