I note that G16 is spare and that whereas some G-code systems use G15 / G16 to switch between polar and cartesian coordinates, LinuxCNC already has polar coordinates without a mode-switch so will never need those codes for that purpose. I like the idea of arbitrary arcs in theory, but at the same time no CAM system would know how to use it, and only a very small sub-set of hand-coders would use it. However those that did might well be very grateful. I think it would end up like the polar-coordinate syntax, useful to those that know about it, but not widely used. (FWIW I use polar coordinates quite frequently, it is ideal for MDI-ing a bolt circle) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
