A: Reverse Y dir pin.

Case 3: X,Y control reversed, X motion correctly, Y motion reversed

A: Reverse X dir pin. Then exchange XY stepper.

Case 4: X,Y control reversed, X motion reversed, Y motion correctly

A: Reverse Y dir pin. Then exchange XY stepper.

Case 5: X,Y control correctly, XY motion opposited

A: Reverse XY dir pin.

Case 6: X,Y control correctly X motion correctly, Y motion reversed
