GITS: SAC Ejection Error

[Drunkenclam]

I was lead to believe some modern machines have a sensor to count the balls as they exit the cel. Not just in the pockets as a way of anti tamper. If yours has one. I would start there. By seeing where the balls exit the cel and into the frame. Of course. Thats buried deep in the machine. Its a know issue for those wanting to make cyclic machines where the ball paths get altered. As yours always does it after 50 balls its a good chance. Is the machine under any warranty from whom you got it from.
