Here it is converted to BW. As I understand it, bmp2cnc will see the grays as different depths, yes?

Yes bmp2cnc will do just that. The trial version is available for anyone but you can't save g-code.

Wanted to clarify ... if you already have Illustrator you don't want to save as a bitmap at all. Illustrator saves its images as vector format which is what CAD/CAM programs need.

Check if Illustrator can save your image as an .SVG file (scalable vector image), if so load it into MakerCam.com (free) and you can define the carving there.

If Illustrator can't save the image as an .SVG file, then load it into InkScape (also free) and then save it as an .SVG file (InkScape's native format). Use MakerCam.com to define the carvings.

Yep, I can export to SVG and open just fine in MakerCAM. It just seemed like maybe bmp2cam was easier?

Yes svg is what you would want to cut paths but if you wanted to do raster carving then you would want to import a raster into a program like bmp2cnc and create g-code. Raster carving is the back and forth g-code type stuff. Bas-relief carving.

List of pixel engraving programs here: http://www.shapeoko.com/wiki/index.php/CAM#2.5D

Guess there are probably enough pixel programs for them to get their own section.

Ah now I understand ... yes bmp2cnc is it.
