After two months of stuffing around I finally fixed the issue I was having with balls not exiting the shooter lane at speed. It was getting so bad I’d have to manually launch balls during multi ball.
I removed the entire mech and all shooter lane parts and swapped them onto my xmen.
Xmen still launched perfectly. :/ weird.
I then did some high speed recording on my phone and compared the ball launch in tron to xmen. I could see the ball slightly wiggle as it started up the lane. When I looked closer I could see a small dent in the lane cliffy. I had mistakenly thought this dent was caused by the ball being put into the lane. But the video showed otherwise.
In the last few frames you can see it move to the side.
It was just enough of a deflection to the left the all the power went into sending the ball sideways enough to rattle it in the lane.
What a difference a fully working machine makes.
Second game after fixing this I finally got to portal, end of the line multi ball and finally got rid of the previous owners grand champion after 16 months!
So time to sell ..... not
