I'm working with an AMH which we'd like to operate, but have found the trough reliability isn't what it needs to be. It often kicks out a ball and immediately ends the ball as soon as it's launched. It seems to do this on the second ball of a game mostly but I've seen it on first and last balls too.
I've run though the switch edge test which appears to detect correct switch movement, but it seems like there's a timing condition which causes the failure. Since this trough us made of long mechanical micro switches which take the full weight and impact of ball movement, I'm wondering if anyone has thought about redesigning the trough to use a set of optos instead. It looks like we could repurpose a Williams trough design and make this game much more reliable.
Anyone ever convert a switched trough to an opto trough?
