 Documentation for the [Clank-LZ](https://gitlab.cba.mit.edu/jakeread/clank-lz) variant, that was used for HTMAA 2020 has been moved into a stable, standalone project [here](https://gitlab.cba.mit.edu/jakeread/clank-lz).

 This is a larger machine, **256x256x128mm**, that uses a taller frame and a cantelivered bed that moves in the Z direction. This platform would be appropriate for jobs with large Z works spaces, i.e. 3D Printing, but also suited for CNC Milling of circuits, molds, components etc.

 making clank into a 3d printer

+- bed assembly is 2770g

 I am building a 'stretch' clank - this is ~ 1024 x 512mm of area: a big flat thing. Mostly because I want to prototype new motion controllers and a simple 2D machine is great for that, and also because I am trying to transition Clank-CZ into a kind of printing workhorse.
