I am looking for someone to write a 3D g-code. I have a 2D autocad drawing. I can send a picture of a finished piece. I have been looking for a 3D cad cam program all day but at this time everything I have found is over my $500.00 budget. I am only looking to do this one code for now, a simple foam carving. There is a ramp in the front about 4" long, 2" flat and a ramp on the end. It is 6" X 20" rectangle.
