That is another possibility indeed. I'll do some searching to see if the Robotdigg rails are good enough or not and assemble a list for all the Robotdigg parts without the electronics and hotend. Do you happen to know wether or not the Robotdigg extruded profiles work with V-rollers or are the linear rails in general better than the V-rollers? I've read a lot of mixed thoughts about V-rollers so far.

That's true. I'll look around where I can get the parts in the EU as it would probably be cheaper.
Thanks for the suggestion!

Okay thanks dc42! I'll see if I can get my hands on some good linear rails instead then.
I've also found an alternative to the Robotdigg vertices, which are these metal brackets [www.amazon.com]. Do you think they offer the same stability to the build like the Robotdigg ones? The robotdigg carriages really look like a clean solution for an open belt but are they really that much better compared to the 3D printed variants?

The rails do not make any noise at all that I can hear, with Duetwifi and high microstepping, I can hear my hotend fan more than any other component.

Couple of things strike me about your build list:
E3d v6 direct - you will surely want a bowden version, even if you use flying extruder there is still a bowden tube. Plus if you buy bowden and go direct no problem.
The brackets I bought which were the Chinese copies of robotdigg, had idlers for 6mm belts with them.
The horizontals at the base 6x 2020 works as it leaves you a 20mm gap for wiring etc...
For the top horizontals given your printer's size I would buy 2040's.
Igus rails are probably very nice but I've not come across many people using them on 3d printers, and they will have more friction when starting from stopped than versions with ball bearings.

Okay it's good to hear that they barely make any noise. The 3D printer would be put in my room and I wouldn't want it to be very noisy all the time.
And oh so that's why you have so many different extrusions in your part list dc42. When I went over it, I was confused as to why you had that many different sizes of extrusions. It all makes sense now and it's pretty neat! Also, at what kind of size would you recommend 2040 extrusions over 2020 extrusions for the vertical extrusions? The Robotdigg XL vertical extrusions are only 2020 and are 750mm long and I'm not sure if they'll be sturdy enough.

When I build my delta, Robotdigg only sold the 2020 vertices. If I was starting now, I would use 2040 because the extra cost is small. I haven't had any issues that I can blame on using 2020 instead of 2040.

I'm still rather picky about the carbon fiber rod ends. I've read some mixed results about magnetic joints in general, but actually quite a lot of good stuff about Hayden's magnetic joints. Sadly they are quite expensive and I don't think they will fit on the Robotdigg carriages. I've read on your blog David that you're using Igus joints over the Traxxass joints. Are they a big improvement over the Traxxas joints or do you think it's better to go for a different kind of joint?
