Well done. I appreciate the effort that you put into showing the assembly from multiple camera angles.

I used to have a super racer before my current printer (X1C). Was a great printer, and I still miss how whisper quiet it was, only the retractions were audible, seems like the V400 is just as quiet. Extremely well built, and didn't have a single issue with it. Still there were a few things missing, and most of those seem to have been solved in the V400. Especially the direct drive, lights and build plate. There's two things missing though, an enclosure and a full metal hotend, the latter of which can be solved quite easily. That would open up a lot of filaments not currently possible. Also with the advancements in tech we expect many more things nowadays (vibration compensation, lidar, almost fully automatic working etc), so I am very curious how the T1 and especially the S1 compare. Only thing they are missing is an AMS type system. The V400 looks absolutely massive though! I already thought the SR was huge, but this dwarfs it in comparison!
