I assume arcbuddy/arcmill can use absolute starting points, but in each case I adjusted the xy start values until the reported starting points were 0,0, so that exactly where it was at relatively speaking. But LCNC squawked mightily. Then I found that arcbuddy/arcmill's default outputs were in "relative distances", so I started wrapping the arc moves between a G91 and a G90. Magic, and everything works. I'll copy the code as it runs right now to that link on my web page, but after I grab some lunch. If I cleaned out the comments, its under 110 LOC I think. But the comments are as much for me as they are for anyone else who wants to use it, my complements.
