I am messing around with the manual/auto plunge challenges today that I have posted previously. I finally took the ramp and plastics off the right side and am adjusting the screw that allows you to ever so slightly adjust the shooter lane exit angle. Its getting better - manual plunge still basically bashes right into the upper left flipper on a full plunge but the auto plunge seems to be accurate 99% of the time where before it was hitting the upper left flipper. Between adjusting the shooter lane angle and dropping the auto launch power to 247 seems to be ok.
A question on the auto plunge - should the ball make it all the way around the orbit to the upper right flipper? I can't remember how this used to work lol - I believe this is the correct behavior.
My machine never had this issue until I decided to swap the factory plunger with the Stern Eddie one - I regret doing it now
