I think that image-to-gcode may be working as designed, though I understand that it's not giving the results you want.
Your screenshot shows that you specified a tool diameter of 2mm and a pixel size of 0.5mm. That means that the tool covers 4 pixels. But in your antialiased images, the blackest parts are much less than 4 pixels wide, so image-to-gcode tries to figure out exactly how far in the tool can go without cutting away any of the material you wanted to remain. (and because of antialiasing and jpeg compression, few of the pixels are actually totally black) There's not currently a way to tell image-to-gcode that you'd rather err on the side of milling away more material. I got results that may be closer to what you want by: * opening the image in gimp, choosing (layers>)colors>threshhold, and setting the low value to about 190. * then set the tool size to the same as the pixel size in image-to-gcode Jeff ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
