There's set screws on the Crane arm and both opto interruptors underneath. Combine those with the two adjustment tests

The deadworld opto interrupter disc wheel only needs to be adjusted if the deadworld does not stop with the ball in the right position.

If the crane isn't above the ball when deadworld stops, the crane needs to be adjusted. There's a wheel underneath the crane that tells it when it's 'over' deadworld using another opto. If the crane moves over the ball properly, but not at the right time, then that's the issue. If the crane never goes far enough to the right, then that's an issue with the set screw on the crane arm

Nr8 on the planet assembly controls where the planet stops. Hard to see what the ones on the lifter are pointing at, I'd have to compare with the mech on the actual machine. But if the ball on the planet isn't stopping under where the crane is when the crane is over the planet, then a combination of Nr8 and the three screws on the planet disc should fix it. I think you can use test 15 (?) (second from last) in the tests menu to see where the planet stops.

Nope, I just tried one until it fit

What I'm going to tell you will probably not be the most popular method, but it's guaranteed to work. Do a full tear down of the crane. Then reassemble all parts making sure you align all set screws with flat spots on the shafts.

Once you verify all parts are exactly where they need to be, follow the crane adjustment procedure through the test menu. That's how I set my game and it worked on the first try and has been flawless ever since. Good luck !
