This project was called Moa as the extinct bird and it included a smaller version called Kiwi, actually already exist 3d printers named Moa and Kiwi (they are not my projects).
I spent 6 month to project this printer, but i didn't reach my targets, so the result is not so innovative to be published.
I share these images because some concept would be usefull for someone project.
Main problems were Z wobble and the excessive elasticity of aluminium.

targets

• original name (Moa already exists) ............Fail

• only one support for Z axis..........................Fail
• only aluminium tubes (bad idea).................Done
• lightweight moving parts in X&Y axis..........Done
