** - 6/29/2012 - go to the post from the aforementioned date to see the new question; I'm keeping my original post here for posterity sake. - **
To Moderators: I know I asked this in my "Pin #4" Thread, I just figured it'd get some better attention if I made this a forum thread. Hope it does not appear that I am spamming D: .
Hey JWS and other owners or anyone that has an idea, I have 2 questions for you...
I have noticed that there are two opto boards in front of the filing cabinet. On both pairs, one of the LEDs is on and the other is off. My understanding of the optos operation is that the ball breaks the beam of light between the lit and unlit LED, thereby causing something to happen - depending obviously on what pin you're playing.
So on XF, you have two sets of optos directly in front of the filing cabinet. From the POV of looking at the filing cabinet, the LED at the bottom right and top left are on, and the other two are off - obviously catching the light beam that the turn on LEDs are sending. For fun, I put my hand in there, and I noticed the magnets were triggered when my hand crossed the 2nd opto switch (closest to the filing cabinet)...
1. My question: what does the first opto switch (the set closer to the flippers) do ???? Is it supposed to activate the magnets first...? If so, mine doesn't.
2. Also, I have noticed from time to time when the ball goes into the filing cabinet to start multiball - it doesn't - the DMD doesn't say that multiball has begun or anything. The machine has to go through its "self check" and once it does that, the filing cabinet moves around and something must happen because THEN the DMD goes through the appropriate animations and multiball begins.
**EDIT to previous paragraph** - at the time that I wrote the above paragraph, I had the machine not completely and properly leveled. I have since taken the leg levelers ALL the way to the ground (meaning there's no more thread left, the legs are as close as they can be to the ground now), and so far everything is good. The manual says these legs are designed to have the game at the recommended 6.5 deg pitch with the leg levelers turned all the way in like I now have them. So, if the problem happens again, my guess is the filing cabinet is going too far down, not allowing the ball to roll out of the filing cabinet and activate the leaf switch that is in the "subway trough" underneath the playfield. What do you all think - maybe I should apply a small amount of white lithium grease or similar lubricant to the motor gears that move the filing cabinet up and down? Those are some of my thoughts - for now though SO far...SO good!
All in all, a very fun game. I just want to learn and understand what's going on here .
