I have been having issues with balls getting stuck on the metal ledge where the ball drops into the unskilled shot. The picture provided shows the hole with the house removed. The weld has is not polished and there is a bump because of this.

The other issue is with the opto triggering when no ball is crossing the opto and causes the game to fire the cellar kick out enough times to disable it till its restarted. I noticed that stern mounts the opto veritcally and the black spot in the metal is the lens of the opto sticking out which is really bad design.

I have adjusted the upper opto and the ghost triggering has gone away. Has anyone tried shimming the bottom opto so its not sticking through the hole?
