Hi Ed,

> Are you guys aware of any free (or low cost) STL to G-Code converters?

Here's one: http://www.mecsoft.com/freemill.shtml

It says it imports both STL and 3DM, but based on the other import formats it may only support polygon mesh data in the 3DM file, so the 3DM import may not work for you, but STL should.
