In the map description a main point is an industrial area with "working machines". So far all I've been able to find is a room with a button that opens a panel, with a clanking noise eminating from it. I've also found a room with a conveyor belt that has two lasers and a valve which seems to do nothing.

Is there more to this, and if so, how do I operate these machines?
Great job on the map, keep it up, proud of you.
