I purchased an AMS 2 pro since they were on sale. Noticed it wasn’t assembled correctly. The bottom tray wasn’t set into the tabs. I was able to pull it apart and fix it, but it makes me wonder is this poor QA? Or a refurb sold as new? Not the end of the world as it appears to function fine. Just had to pull the two screws in the back and lift it up and slide it in the tabs. Bambu has instructions on how to disassemble if anyone else gets one like this.

Welcome to the forum.
This part might have shifted during shipping. Good job getting it sorted out.
