turning a image/model into directions for motors

[elexolman]

I really, even though it is using USB hardware, would not refer to it as USB, since the device uses a virtual com port driver to make it as if the USB port was a COM port, making it easier to program (and simpler if I use a machine other than my own, and COM ports are going away on many comps)... and it looks like the .DXF thing would work for me, but I still would like to be able to use a 3D model... maybe I'll save that though for an update : )
right now I am looking at mach3, and it seems that there is a dev version, which might help me out a LOT!...

The development version of Mach3 is just the most recent release, it won't give you any code to look at. You might want to look at the source code for EMC. Part of Mach3 was based on the EMC code. Be aware that Mach3 is the result of one person working 8-16 hours a day, 7 days a week, for almost 5 years to get where it is today.

I meant the SDK that appears to be available...

[ADDITION]: just thought I might put this out there, thanks to the Arduino I recently got, I also can now make the machine not need a computer (assuming the raw directions for a set, but re programmable, output are made first)...

My mistake. Looks like Switcher and Ger21 Know a whole lot more than me about that, no surprise there.
