I’ve been given some linear rails, and the only thing I can think to do with them is build a large format 3d printer. I have two 750mm and two 670mm rails, two carriages each.
I know there are several open-source plans for printers, and I could use a cool project to work on. I already have a smaller printer to work with so I can already make a lot of the parts.
Has anyone done this before? What printer did you build, and do you have any recommendations and things to look out for?
The entirety of voron is an open source project, they do not make or sell printers or parts. None of their printers are designed for this size, though. People have definitely made custom ones larger than the schematics but there are drawbacks for going even 50-100mm over the normal max of 350mm, doubling it would certainly require more engineering than “print some parts longer”
IIRC there’s someplace on their website or manual where they explain why 350mm is the max they chose, and a big reason was the wobble/flex that you’d get from going over–you’d have to compensate for that by designing a much more rigid frame and not just scaling the Voron design
