Thank you for letting us visit your center. We installed your Startgate, we aligned lasers, found 3 bad receivers, adjusted the oculas, set in maze configuration, found one laser that has bad adjustment screws.
We recommend getting 3 new receivers and 1 laser. We can also send a few wall brackets as some were loose. We will look for your Startgate payment soon.
Also, please find the programming guide for oculas. Please not that position a and b are swapped in the instructions but it should still be helpful
