cadcam anything with different kinds of parts on a fixture saved as one STL file and solid verified should do just fine. Different sized blocks with holes, does not matter can be very simple. As l mentioned the trouble I am having is my tools are cutting air not the parts. Not sure where to set the origin for the saved STL file? Maybe this is the problem? Also, would like to know how to control the light for solid verify. Often my part to be solid verified is in the shadows.
