Large Format 3D Printer

[Snyggis]

Greetings,

I am looking at building a new large format 3D printer. Planning to run at least 4X4X4 footprint. I have a few questions:

1. Belt Drive - Does anyone have experience with these linear drivers?

This video explains them quite well, I've struggled with lead screws on large sizes, so those are out. This seems easier than a rack and pinion setup.

2. I love the KFlop for CNC machines, but am nervous about running G-Code for a 3D printer. The documentation for Knozz talks about using craftware. Has anyone used this or comment on how tedious it is to add that extra step into the work flow?

Thanks!
