A new possible problem started last night with my cannon. I had the cannon qualified to shoot for the song jackpot and I loaded it. The cannon started its outward swing towards the AC/DC targets, along with the "cranking" sound it makes, then it suddenly went silent, but continued to swing out to shoot the targets and fired the ball on its own at the AC/DC targets.
I know this occurs naturally in the software when you load the cannon twice in succession without jackpot qualification, but at those times it always shoots the ball towards the TNT targets. This one is totally different, in sound and function, and it has happened twice since last night.

Anyone seen this yet??

Thanks mandelbloom! I remember this thread a while back. Shoulda searched
I've done work to the underside of the cannon in the past, so it's possible something got jogged in the process. I'll recheck the switches tonight as well as the mechanism.
