Quoted from chriscable34:It hangs up during rotation. Sometimes it get hung up 90 degrees off from where it should be. You can here it sound like its straining.Sorry I should have been clear on the issue I have with it. I have a video of it acting up but don't know how to post it.
I had the same problem. I reseated all my connectors to the opto board under the playfield and then it was fine.
