The flippers on my NF are "week" when I try to catch and hold the ball. On slow balls it's no problem - the bat will catch the ball and hold it without any problems. But once the ball speed goes up making the impact with the bat harder, it will "flip" the ball even though I have the button on hold.
I've cleaned the optos, cleaned the EOS switch and tried ajusting the EOS but without luck.
I think the ball will hit the bat so hard that the EOS is disconnected which will re-fire the main coil and send the ball off rather than holding it. But - it's just a theory. Can be something else.
If you think it's an EOS issue - should I then make the gap smaller or larger?
Looking forward to hearing your ideas.
