Looks like a little less needed force would be nice, but it seems the idea will work
Could not resit playing with it myself a bit, made this based on the ReprapBCN-sigma idea, in itself it's not so bad as the space mid-front is lost anyhow. You do lose Z depending on how high you make this thing, but thats not my main concern, the constant Z distance needed is more anoying imho.
Basically I like the idea of wipers on the side better..... Now I'm just thinking if I dare to drill holes in my UM2 side panels :( maybe it's better to glue a mount inside ..

Back of the machine it's nice if you don't use bowden (or you move the extruders to sides/front). The preassure from the bowden on the back push the parked head and it's almost impossible to have it steady from the bowden and the 'shakes' when printing fast small areas. If you use direct drive it should be fine adjusting the hangar I think.
I did loose a lot of time trying to place them there and tryed almost everything (with bowden ofc).

Curious about your result... been thinking myself to go for a combination of a UM2 head and a V6, to be more flexible with higher temperatures on PET/XT, but I started with just the UM2 head setup in order not to change to much at a time..

Yea the biggest attraction for the v6 is the temperature range. I've got some nylon i'd like to try printing with. Also goes for direct drive so think making a chamber could really help with printing these exotic materials too.
Neotko, know what you mean about the bowden issue. I'll give it a go, if it doesn't work out I can always turn the main carriage around and have them stored at the front. Either way, i lose around 30-40mm of print area. I'd really like to reduce that, but to be honest I seldom print anything that uses the full bed. Maybe we need to work on a mechanism that somehow lifts the parked heads out of the way, or swing them to the side or something...complicated though. I'd better get it working as standard first really!

Filament wiper addon. I need to improve it so it's easier to remove without compromising how steady it is.

Nice one! Although it sounds like a pinball machine![:p](//content.invisioncic.com/ultimake/emoticons/5a33abe3e5fc3_1f61bcopy.png)
