Do not buy an Aurora Z605 (i3 clone) whatever you do, waste of money..

Honestly go for a Kossel mini mate, much easier first build and you can make most of it on your Flashforge.

I Went FF -> Prusa -> Kossel

I wish I had gone FF -> Kossel -> Prusa

The kossel made alot more sense when calibrating it and took half as long and the beauty of the delta rig, as soon as you build one - you instantly know how to build a bigger or smaller one, and you can.. It's like a parametric design almost.. with some exceptions.
