Hi there, I just purchased my first machine so I'm pretty new to this.

After some manhandling by FedEx, there were a few repairs needed due to components falling out of place such as the name-sign animatronic having fell off its track, so this issue may be related.

One pair of the animatronics is giving me trouble especially at startup. They get stuck, out of sync, or their motor will loudly try to push them further than possible when they reach the ends of their track. This results in an error 99: 役物初回起動エラー

Here's a video of this occuring:

How should I attempt to repair this?
