As visible in the attached image, the crane is not passing above the ring at the right time to pick up the ball.
How do i calibrate this?
As visible in the image, the slotted holes only give room to adjust the ring goint the other direction.

Hey, thanks
But, the crane arm-screws only adjust the cam that animates the height of the crane right?

so by opto-interruptor i guess you mean, adjusting the set screw / shaft position on the big wheel under the deadworld ring?

Just to make sure we are talking about the same adjustments:

Attached images:

In "Lifter Assembly" image, do you mean nr5 or nr17 ?

And

In "Planet assembly" image i guess it would be nr 8 ?

To me it seems as if the crane position ends up perfectly above where the ball should be, the problem is that the ball is not there, its 2cm further down the rotation of the ring.

Yes, i think i might need to adjust nr8 on the planet.
I tried with a tiny hex key, however it seems to be really stuck, i am worried i might break something there.
Any idea about what hex key / tool / size needed for this?

Ok, ill do my best! Much appreciated Zacaj
