The problem is due to the mirco play field

The bevel into the wood that creates the shooter lane is shorter than your original play field by an inch or two. If you still have your old play field this is easy to see if you compare them.

So it creates inconsistency by the time the ball enters that metal portion of the lane

I struggled with your same probelem for weeks.

I only solved it by adjusting and readjusting the leg levels over and over. I solved it with a perfect 6.5 degree pitch and a 0.2 degree difference from right to left measured exactly above the slings.

It helped me a ton by filming the ball plunge in slow motion with my phone. Then you could see where the ball was pulling right or left.

I had your EXACT problem

The 0.2 degrees is higher on left side of machine.

I spent a lot of time adjusting the shooter rod but did not get to the level of detail it sounds like you did. But visually, my shooter appears to hit the ball dead center from left to right but maybe a tiny fraction above dead center from top to bottom.

This solved it for me to the point it’s probably 99 clean shots out of 100.

And the 0.2 degrees is not noticeable during game play. I even drop a ball from top of play field to see how it rolls, and it is so negligible the ball doesn’t really pull at all.

I looked at your videos but they’re not in slo mo. (Unless I’m missing something). I really can’t recommend slow mo enough because it makes it so much easier to identify the ball path.

I also forgot to mention I very slightly bent/manipulated the metal rail that ends right where it transitions to the rubber and the ramp flap.

In slow mo you can see the ball rides against this.

My game is folded up at the moment due to some basement work being done. But I am happy to send you some pics of mine if it helps. Like I said, I feel like I was able to finally overcome this and dial it in.

So if you continue to have issues just let me know.
