Quoted from rvermeire:Slot reel issues.
Had one reel not being in sync with display.
Took it off and did a motor test. All 3 wheels spins in test mode and left and middle keeps on spinning till I press stop. The right, issue one, stops automatically after 5 seconds...
I unmounted motor and checked for dirt, nothing there all clean.
I changed the power cable (4 pins plug with also 2 blue cables) from left to right wheel. Now it's the left wheel that stops after 5 second !!
Something must cut off power to this plug after 5 sec....??
Thx for suggestions...
It stops if the opto isn't triggered for a certain length of time. So you either have a dirty opto, a bad opto, or the wheel has gotten warped and the gap that triggers the opto is now too far away to trigger it. In test mode is that wheel triggering the opto on each revolution (it makes a sound and shows on screen when it's triggered in the test). It's very fussy about the alignment of the wheels, so if it's even a little too high relative to the opto channel, it may not trigger.
If you're saying you changed the opto board attached to each wheel and the problem moved, then the board may have a bad component on it.
