RE: [CAD_CAM_EDM_DRO] Re: creating toolpath..

For simples shapes and pockets you could also try the software I am creating
called GenGCode. It's still alpha, but producing usable gcode for cutting
rectangular and circular pockets, also slots and circular drilling and
ellipse. Designed for the CAD challenged.

You can download a copy from http://home.inter.net/mthomas just follow the
link to GenGCode.

Cheers,

Mark
