Officially joined the club today and pretty stoked to have one of these... BUT
After setting up the machine in my basement and powering on the game for the first time (coin door closed, high power active) the building motor emitted a continuous whirring / whining noise after which I immediately powered the game down.
After shutting the game down, I checked both above and below the playfield for any physical obstructions to the building (i.e., loose wire looms, etc.) as well as checked whether the building was making contact with the sides of the opening in the playfield. I found no physical obstructions that would cause the building to "stick" which in turn would cause the motor to just whir / whine. I then attempted to move the building's lifting / lowering mechanism by hand by turning the belt manually. I first lowered the building and that appeared to work fine as the building appeared to lower to its resting position without issue. However, I then tried raising the building to its highest position. That was problematic. While I could raise the building partially by manually turning the belt, at a certain point, it would just stop moving as if the mechanism was blocked from the inside. I suspect this "blockage" is what is causing the whirring / whining motor noise that I hear (i.e., the motor is attempting to raise the building fully but cannot do to some obstruction in the mechanism).
I presume something got jostled / jacked up in shipping or else there is an issue with the mechanism itself. I have just sent an email to Stern and hope to hear back in the coming days but if anyone out in the Godzilla universe has any ideas as to the possible issue let me know. (May 31, 2022 Build BTW). Thanks!
