Initially, I had the idea to rebuild my old (outdated and partially broken Reprap/Prusa) into a robust 20x20 frame. I also wanted to have a larger (especially in z direction) build area and a to have an isolated build chamber.
Well, this is what came out.
It has the following features and drawbacks:
- Everything is robust :) With the right tools, etching and milling (in wood) should be possible.
- Everything is in a box.
- Build Volume is 200x200x400, although you can print up to 250x250x400 Vases that start on the 200x200 footprint.
- It's an easy and well proven design. It fixes z-wooble, z-inaccuracy and z-backlash issues by using using backlash nuts, by using a fixed (in z-direction) lead-screw and by fixing the z-axis in a robost frame.
- Well, it's not optimal with respect to build volume, if you want to maximize it out, you should go with a nice CoreXY design.
- Well, it's also not optimal with respect to maximum speed, since you have to move the mass of the build bed in y-direction.
