I wonder why you'd prefer rails over shafts & linear bearings.
I'm playing with the same idea, basically the H setup like in the Builder. I'm just still in doubt if I want to go for two motors/heads mounted on it (like the BCN sigma) or to stick with the magnetic mounts... I think I'll start playing with both ideas in CAD first.
Even one week after finishing the strike German Post is not up-to-date with its delivery and so I'm still waiting for belts and pulleys. Otherwise I'd soon be able to report on a first test of the x/y gantry. I went for linear rails basically because I'm lazy (simply bolts on to laser cut metal parts) and many printer manufacturers use them as well.

Any luck with the e3d ultiarjan? I'm trying again, e3d sent me a new kit, and i got a spare heat break for the no.2 unit. I have updated my design to improve the cooling, and designed the second head to be height adjustable. So, the e3d....I have managed to print a robot, but whenever I try a longer print, I get a blockage still. Its super frustrating as i'm convinced the design is good. I am trying now with a different bowden tube (the other one i was trying had large ID). If that fails, the last thing i'll try before giving up, is a drop of oil in the bowden tube. I'm reluctant to do this as not sure if it will affect the strength of the prints. So close yet so far!
