In alog #2034, we mentioned an issue probably created by a malfunctioning actuator in corner 2 (Horizontal - NW). Two modifications were made since the issue was mentioned:

-          Disconnecting and reconnecting the actuators (Horizontals and Verticals separately)

-          Swapping the actuator valve of horizontal actuator in the NW corner

After rerunning the test (attached figure), you can notice that corner 2 (NW) behaves more linearly (not the case of corner 3 after the actuators reinstallation).
