I have the Gunfighter Tabletop Grip: MCG PRO w/ Built-In Twist and the Y and X Axis are working fine now. When I am trying to calibrate, the Axis are fine after I added new cams and springs. The Axis are recognized in the calibration process but not the buttons. Also, on the testing. I can see the base in green and communicating but the grip is in red and looks like not communicating. Why are the buttons not workin?

There's a connection problem, most probably the grip is not seating properly on the base or the fastener is loose.
