Hi Todd, The only reason for "messing" with dfx2gcode as a middleman is that it has a "drag knife" setting, which (I hope means) "on the line, corners over x degrees exceed by caster amount, lift Z routine for caster change to new direction" I wanted to see how that routine worked as far as g code.

I've tried two coming from Freecad, both saved as "Autocad dxf", one was a simple 2D fully constrained 20mm square and the other was the same thing padded to a thickness of 0.254 mm. I can try a dxf from another source if that is the problem.

This was supposed to be a quick project. That looks like a bug in dxf2gcode. Can you post the DXF file that causes the problem? -- Sebastian Kuzminsky _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
