I encountered a significant challenge with the house rejects, as only 20% of the shots to the house would successfully go through. The remaining 80% would reject and return down the house. After experiencing several frustrating games, I decided to investigate the root cause of this issue.
Upon removing the house and examining the ramp, I observed a slight misalignment between the movable ramp and the shelf above it. The ball trails on the sides of the ramp clearly indicated that the ball was launching off the shelf and propelling upwards.
To rectify this issue, I removed the movable ramp, carefully adjusted the hinge mount to raise the movable ramp to match the height of the shelf, and reassembled the entire mechanism. As a result of this adjustment, the shot to the house is now 100% successful and operates smoothly.
I am sharing this solution in case other users are experiencing similar issues.
