I think this is already in the plans, but I second this suggestion.
I recently got into 3D printing and it's amazing that there is free software available for every step of the way, from design to modelling to output to creation of the G-code, etc. - all free. For example, I can use TinkerCAD or 123D Design to generate a 3D model and then output an STL file - from there I can import the STL file into one of several free slicer apps to generate the G-Code and copy it to the printer.
You look at hobby level CNC and you don't find that same free chain of software. There is free software out for some of the steps, but I've yet to find a completely free path from design to machining that doesn't require multiple steps, conversions from one format to another, or some annoyance along the way. If Inventables can add that type of support to Easel, it adds a tremendous amount of value to their product line!
Does anyone know of a free route from design to machining - on Windows - with minimal steps and/or conversions?
