If what I'm working on works... Anything that spits out gcode will work. I've never used Simplify3D. I'm looking at integrating my code into BeagleG which is a gcode processor for a variety of hardware platforms for Beagle's. Once I'm done (as as I make progress), the code will all be open source so anyone can help add, modify, fix, or improve it. There won't be any limits on what it'll be able to do (unless I completely fail in getting control of it, but I think I'm fairly close; so long as I find the free time).
