Quoted from dboeren:I have the rattley plunger issue and I've already added the 3d printed ABE Flips piece but it's still rattley. What else should I do?
Here is everything I had to do
Install pf stabilizing brackets (my game came without them and the back and forth play in the playfield meant the shooter rod could not be consistently centered on the ball).
Adjust the shooter rod housing to center plunger on ball horizontal/vertically.
Replace outer spring with a shorter spring so plunger tip is closer to ball.
Abe fix was the icing on cake that made it very consistent. Although I made my own it was based on Abe’s findings.
If you search for my posts in this thread you can find more details.
Love GZ, but really surprisingly bad all I had to do for the game to do a very basic pinball thing - shoot straight.
