MMU2 Assembly instructions. Seems like a strange order.

Bought my printer assembled. Also bought the MMU2. I understand it said it was a kit. I assumed that meant the parts would be assembled and then added to the machine. I had no idea every screw, bearing and sub-assembly would have to be put together.  OK I can put stuff together. But I would have paid more not to do this.

Then I look in the book. No instructions there. Go to the web. Obviously  the web will contain the latest changes and larger images.
It seems strange to me that after the Introduction, the first thing you want me to do is start disassembling the Extruder.  Wouldn't it make more sense to build the actual MMU with all of it's parts first, then work on changing the extruder to accept the newly assembled MMU unit?

It just seems out out of order.

Exploded views of the sub-assemblies would be nice, to visualize the assembly process.

I cant find any pictures of what this is supposed to look like with the spool holders and buffer assembly completed and connected to a machine. Near as I can tell, the spool holders will sit on a shelf (of unknown size requirements) behind the printer. Where the buffer assembly sits in relation to everything else is still a mystery.

The handbook has good information.

And I really like this video to see what the MMU does during all the different load and unload steps.

Thanks for your reply. The video looks like it will be very helpful. If I sounded frustrated, it's because I was. Didn't expect all the time to assemble the MMU and all the disassembly of the print head. As it is now, I believe everything is done, but not adjusted or tested.
I was hoping this was a unit that I could attach and use for multi-material work and then (maybe) remove for single filament parts. With the amount of disassembly/reassembly of the head, I can see that's not the case.
I still have no idea what the Buffer is for, where it goes (not in the instructions), how it's attached, or what it's purpose is. I skimmed thru the video and didn't see anything there either. Haven't found a single "big picture" view of how it gets connected.
