Hi,
Just wanted to post this in case other MMR owners run across the same issue. I setup my machine today, and when I went to play I noticed the left popper never fired, checked the opto in switch test and it tested out fine. Turns out the folks that assembled the machine had wired J4 into J3, and J3 into J4 on the solenoid driver 3 board. Once I swapped them around problem solved. I also have a small paint chip on the side rail. I'll open a ticket to see if there is any touch up paint available. Overall I'm happy so far with the machine.
Here are some pics of the new addition
