I fully assembled it last night. I haven't tested it out yet and I do have two issues.
The heat bed a bit wobbly and the right side z-axis passive block wheels are a bit loose and it's affecting the arm.
My son says the Ender 3 v2 is "the best one".
The bed wobble "is completely normal, it's due to the tensioning springs being compressed when you wiggle the bed plate. That doesn't happen while it's printing. Just make sure you have a spring under each of the four corners of the print bed."
For the arm having a hard time going back up "this is normal. It doesn't prevent the printer from working but it sucks for calibration. If you want you can loosen these two screws, but only a little bit. It doesn't have to be half out. Maybe a half-turn."
For the right side z-axis passive block wheels, "I'm guilty of having that loose too but it's never been a problem. But if you want to fix that, try tightening this screw. Thanks for remind ME to tighten that one."
