Ball Keeps Bouncing While Flipper Captures It

This probably (hopefully) has a very simple solution, but I have an upper smaller playfield in the table I'm working on, but for some reason when the flippers extend to capture the ball, the ball slides up the in-lane and bounces against the flipper's rubber seemingly infinitely. Not only does this not make sense from a physics standpoint, it makes it hard to play and control.

 

I've tried reducing the flipper's bounce as much as possible and raising the friction, etc, and messed with the angles of the in-lane as much as I can without ruining the structure of the playfield, but it still bounces up the in-lane and back against the flipper over and over. I'm not sure what the other physics settings for flippers do, so any advice is appreciated!

Maybe you have too much empty space between the flipper and the inside lane guide, try adding an invisible wall to close this space.

So it's "falling" onto the flipper every time? Yeah good point. There's actually NO empty space and the guide actually overlaps the flipper, but maybe that's making it think it's falling. I'll try to perfectly mold the guides to the backs of the flippers and see if that helps.

This use to happen with many of my tables. I never found a solution, but changing flipper and wall parameters use to help sometimes. But in the older VPX version there were too many collisions, even when the ball was still in one place. Try the table with the VPX8 RC4 and see if the problem is still there. I know that vbousquet has reduced the number of collisions when the ball is resting. Maybe he fixed that problem. I do not have any table with this problem anymore, so I can't test it.

Out of curiosity, does this happen to you with smaller than normal flippers?

 

I have a table with 2 inch flippers,

from time to time when I hold the flipper up to stop the ball,

the ball makes one or two small unexpected bounces upwards.

Yep usually smaller ones. I actually more or less gave up trying to fix it. Call it an extra challenge I guess. It's not the main playfield flippers so whatever.
