just had a quick look at TZ and the "no powerball" settings is set to NO. Both the slot machine & shooter/plunger was not detecting the powerball.Tomorrow I will have another look at proximity board, but last time I checked, the LED was coming on when the metal ball was in the shooter/plunger but I will check this to confirm it.Also is it possible for the proximity board to be detecting ok but not sending out the right signal. Forgot to check for sw 26 error but will check this tomorrow.
