I think the easiest way would be to generate the angle commands externally and just put them in the gcode. The calculations are trivial for lines and almost as trivial for arcs (since you can move rotary axes in sync with the arcs). This solution neatly avoids the problems like how do you lift and turn the knife? How do you know what should be a sharp corner? Kinematics seems like the wrong place for this since because of exactly the problems you already forsee. ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
