That sound like fun. Not many people get to use G-code dimensions in feet. Bear in mind that it doesn't matter that much where you are, just that you know where you are. As long as each reading has an accurate coordinate, then it is good data. You can always regularise your grid later with a Delaunay triangulation and bilinear intepolation. (I have code). Or use the Matlab "griddata" command. Look on eBay for old laptops. It seems that older ones tend to have fewer problems, and parallel ports. You could probably speculatively buy several, pick the best and sell the rest back for not a huge loss. I recall reading a paper a long time ago that suggested that a fractal was a better way to scan an area than a standard raster. long-term systemic variations get averaged out better. (though the application was electron microscope scan patterns) (Back on subject) EMC actually seems quite a reasonable fit for this job. -- atp ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
