Quick MMU2 Test Print
I just received my MMU2 and I had no idea how it was going to change the way I design things. I am so incredibly impressed by the hardware design and simplicity of setting everything up in Slic3r.
Here is my first attempt at a multicolor design. It is super small and perfect for anyone that wants a quick print on their new MMU.

Looks sexy!
Can't wait! Mine should be shipping any day now. Really looking forward to unlocking my creativity with multiple colors. Not looking forward to spending hundreds of dollars on new filaments colors to play with, though ;D
Ordered a roll of BVOH as well. Really looking forward to playing with that, as well. I'm really hoping I can get some nice smooth finishes on my overhangs, rather than the nasty lumpy mess I get now, after removing supports. I 3D printed some new glasses frames for myself the other week, and I'm really happy with the design, as well as the fit. But after a bunch of prototyping to fit the frames to my head/face shape, I ended up with angles and overhangs that leave one side of the frame being rough/ugly because of support material.
How long did it take you to get the MMU2.0 up and printing successfully? Any special tips?
Re: Quick MMU2 Test Print
I am not familiar with BVOH. I bought some PVA, now I'm wondering if I bought the wrong stuff. I was looking for a good water soluble support.
In regards to the MMU2 setup, there were a couple of things that caused me delays. First, I am horrible at thoroughly reading instructions and assume I know what the manual is going to say (and I never learn). Right off the bat I put the bearings in the wrong order and had to destroy/reprint a part. Secondly, I have a LACK enclosure and had to figure out a way to cleanly get the teflon tubing through the acrylic on the back.
One thing you may want to consider while you wait for the arrival, print a new einsy housing. The solution in the manual for making room for the MMU wire was to cut a notch off the door. Another forum user made an awesome einsy case to solve this issue: https://shop.prusa3d.com/forum/user-mods-octoprint-enclosures-nozzles--f57/upgraded-parts-for-mmu2-0-t24379.html#p114352 It also solved the issue of my wire bundle continually slipping out.
The manual is really well done, if you read everything thoroughly it should be a breeze. Also, make sure you ration your gummy bears.

Good tips! Thanks a ton!
How about that LACK enclosure though? I've got one myself, but I'm not sure where I'm going to mount the FIVE spools of filament. Right now I just put a spool on top of the LACK, and it passed through a drilled hole in the top. Works fine for one roll... but when there is 5... gonna need more holes I guess.
Where did you end up mounting your spools, if you don't mind me asking?
Re: Quick MMU2 Test Print
I knew when I started building the LACK enclosure that the MMU was coming so I tried to plan for it. There is a user on Thingiverse that made the LACK table extensions which increased the height of the enclosure to accomodate the MMU2. Without the extension pieces the MMU2 will not fit.
The bigger problem for me was transitioning through the acrylic, and still being able to pop the top off simply. I made a 45 degree quick disconnect that is coupled with magnets: https://www.dropbox.com/s/dw6w08o5eqw30ml/IMG_3701.MOV?dl=0 - less than $10 in parts to make and it really does exactly what I needed. Also, it makes it easier to change filament. The little anti-tangle mechanism on the spool holders work great, however it makes it a bit tougher to swap spools. With this coupler I just release the teflon tube, carry the entire spool to the workbench, and change it.
I attached a picture of my enclosure. I have only done 2 filaments at a time, but the positioning of the spools seem like it will leave enough room for the filament loops. Let me know if there is anything I can do to help!

Wow, Nice setup.
