Quoted from LTG:Balls magnetized and sticking in the ball trough ?
Plunger that kicks the ball up to the shooter lane sticking up a billionth of an inch too high and not letting balls roll into place ? ( It is adjustable, four screws hold coil/plunger bracket to end of ball trough, can be loosened and raised or lowered. Don't go too far either direction )
LTG : )
I think it might be the coil/plunger now that you mention that. I'm glad to hear it can be adjusted. Thanks a ton, I'm going to check that out tonight.
Quoted from PinMonk:For #1 it sounds like maybe the machine isn't level side to side or the balls are magnetized.
For #2 the wire on the switch needs to be adjusted so a slow ball can always trigger it. Using a wire switch there was a TERRIBLE design choice. It's butted up against stuff underneath and getting it adjusted perfectly is time consuming. Basically just bending and tweaking the wire trigger side to side and back and forward until it's just right. Once you get it right, it will stay, though. I was adjusting it on and off for about a month and after I got it right, it's stayed good for almost a year now.
That's great to hear about #2, I did not realize it was a wire sensor. Opto seems ideal there, but that's probably more $$. Thanks for the help. Great community here.
