Here's another issue with my TNA that just started happening.
When I'm in single-ball play and the locks are empty and ready for balls to lock, fast-moving balls will hit the back drop target and bounce completely out of the lock lane and back into play before the 2nd drop target rises to trap the ball. These same fast-moving balls were being trapped just fine earlier today.
If I roll the ball slowly into the locks by hand, the 2nd drop target raises in time to trap the ball.
I tried this with debug events showing on the display. Both opto 1 and opto 2 are registering even in the case where the ball bounces off drop target 3 and escapes back into play.
The problem seems to be intermittent, but if it happens, it'll happen repeatedly from then on. If I power off and leave it a while, I may not see the problem the next time that I power on.
Any suggestions for this one?
EDIT:
Mystery solved on this one. The problem goes away when DEBUG mode is disabled. Apparently, displaying the DEBUG event messages slows things down enough that the drop target can't be raised in time for fast-moving balls. Sorry for the false alarm.
Thanks,
John
