OpenBuild vs linear bearings

I'm interested to hear opinions on the comparison between OpenBuild rollers and actual linear bearings. I would think the rollers would be good at reducing vibration. Could one generalize.. small build platform, small parts = linear bearings. Larger parts, 300 x 300 platform with larger nozzle = Ope...

Re: Starting i3 build looking for help

You're making way too much sense. There must be something wrong here :lol: So as I said, I have been looking for an excuse to work with these kinds of erector set extrusions anyway. And they have the benefit of being useful to re-purpose as well. Have you ever considered welding any key spots for ex...

I'll have a look over your links and see what brain cells fire 8-) Did you consider using 2040 on the uprights? The thing I like about the Black Widow over t...

Starting i3 build looking for help

Newbie here, I'm hoping to build a 30 x 40 i3 clone for my first 3D printer. I would buy a genuine Prusa, but I want a steel (or alu) frame, and as much 24 volt stuff as possible. Can anyone point me at any good resources for someone in the US to get started with sourcing parts? Does anyone do steel...
