This would be very useful for opencamlib also. For slic3r G-code I guess you can assume all arcs are in the XY plane, for opencamlib I'd like to extend that to XZ and YZ planes also. You have two tolerance parameters. From a user perspective only one tolerance, the maximum deviation from the arc to the programmed g-code lines would be preferable? Is there a maximum and minimum allowed radius for the arc? (a straight line is in theory just an arc with a large radius :) Anders ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
