What I was going to clean up with the dermal was little areas in between the letters that the 1/16" bit could not fit into. Is there another way to clean out these areas with the code?
I work with MeshCAM Art, for my 3D stuff. It does a great job, since it creates a tool path for the roughing cut, as well as the finishing cut. (I usually use a 1/4" bit for the rough, and a 1/8" bit for the finishing cut). You can actually "LIE" to MeshCAM about the diameter of a tool (I tell it the .125" bit is a 0.94" bit). This forces the software to create a more detailed tool path for the finishing cut. However, since most of what I carve is recycled tractor-trailer flooring, (Oak) it still sometimes requires some touch-up work by hand using a Dremel tool. As for areas that are too small for the tooling to reach into, this is best handled at the artwork design phase. Simply space the letters further apart, to accommodate the tool diameter. I use Corel Draw in designing my artwork. And what I typically do, is to draw a circle .125" diameter, and drag it around the drawing using it as a "measuring device" to check the spacing of my artwork. If it won't fit between letters in the design phase, then the bit won't fit between them when you are carving. I have found it to be a great time-saver, for checking the artwork prior to tool path creation.
