"Upgrade" an MMU2S kit that's still in the box?
So back before I changed jobs, I had this printer at my big workspace in my office. I bought the MMU2S kit for my MK3S, but then changed jobs before assembling it. I went for a long time with absolutely no room to set out 5 spools, so I didn't bother assembling the MMU2S.
Now I'm getting back into printing again, and just ordered the MK4S upgrade for my printer, but the MMU2S isn't compatible with it (correct?). I was thinking of ordering the MMU3 upgrade at some point in the future, but am concerned it might be difficult to basically just assemble the whole thing from scratch, thinking that the upgrade instructions will assume the MMU2S is already assembled.
Has anybody done this particular "upgrade" before, or had any documentation on this process?
