I initially envisioned rebuilding my outdated and partially broken Reprap/Prusa into a sturdy 20x20 frame. I also wanted a larger build area, especially in the z direction, and an isolated build chamber. Well, this is what emerged. It boasts several features and drawbacks: - Everything is robust, and with the right tools, etching and milling in wood should be possible. - Everything is contained within a box. - The build volume measures 200x200x400, although prints can reach up to 250x250x400 for vases starting on the 200x200 footprint. - It's an easy and well-proven design that addresses z-wooble, z-inaccuracy, and z-backlash issues by utilizing backlash nuts, a fixed (in z-direction) lead-screw, and a robust frame that fixes the z-axis. However, it's not ideal in terms of build volume if you want to maximize it. A CoreXY design would be more suitable for this purpose. It's also less than optimal in terms of maximum speed since you have to move the mass of the build bed in y-direction.
