I have done some more experimenting this evening. It is only the Data East tables that are having lost balls when they enter the plunger lane. Jurassic Park actually said "two lost balls" on the DMD after multiball. Guns N Roses and Rocky and Bullwinkle are having the same issues. I am sure that since others aren't mentioning it on the support threads I must be causing it with the contactors when the ball ejects into the plunger lane.
I experimented with the nudge settings in my VirtuPin settings. I also experimented with the Max x,y and Gain x,y in the VPX 10.6 nudge settings. Using the nudge calibration table I have wound up with a considerable bump required to make the balls twitch. But when you fire the back four contactors using the coin button in the nudge table the balls still do a side jump that is quite noticeable. When DOF senses a ball put in play on my Data East tables it fires all of the back contactors I believe. This is what is causing the ball to jump and roll back into the drain area and be lost to the plunger.
I am thinking about mounting my VirtuPin accelerometer board on a foam rubber gasket to isolate it from the "thump" of the contactors. Has anyone else had to use this technique?
If I could minimize the propagation of the contactor vibration to the accelerometer then I could turn my nudge sensitivity back up to a reasonable level so the balls in play can be nudged without banging on the cabinet so hard. The cabinet itself is well built with 3/4" cabinet grade birch glued together. The accelerometer is mounted on a crossmember "shelf" that is just in front of the coin door. I think this heavy cabinet transmits the contactor thumps efficiently to the accelerometer.
At the moment i have X and Y Max set at 100 and x,y Gain set at 150. VirtuaPin nudge sensitivity and LED sensitivity are both set at 4500 (excluding this issue I like 2000 on this setting for comfortable nudging).
Any suggestions appreciated.
