Lathe Software

Hello folks, new guy here.

I wrote the web pages for http://www.deskam.com in return for his
software... great deal for milling machines. Anyway... I am thinking
of modifing my lathe to CNC and his software doesn't convert my DXF
into LATHE compatable (X/Z) G-Code.

Is there a cheap or free program out there that will do the DXF to
G-Code for a LATHE? I can draw either the shape outline or the
toolpath in AutoCAD.. just looking for a simple conversion.

Thanks a bunch,
Jerry Rutherford
