I bought a Nomad 883 Pro last year and it’s mostly been sitting because I haven’t had a project for it yet. I have an Epilog 40w laser and a manual mill/lathe combo that both see more use. Well, now I have a project lol. I need to engrave some aluminum for a wax stamp. I’m seriously rusty with my CNC skills and I’m looking for some advice on using the carbide 3D software to set this up. I converted the file to an SVG and resized it etc and brought it into Carbide Create, added a circular border to it so that when you press it into the wax, you get the client’s initials and circular border. And that’s when I realized that the tool paths are all going to carve the two circles and the letters. I am having trouble figuring out how to invert this. I want to mill the background and leave a circular wall .050" thick around the raised letters. Right now if I cut it I’ll get two circle paths .050" apart and engraved letters in a flat surface. I attached an image of the laser cut ones to show what I want. What I’d get with the file as it is would be inverted…raised background. Any help would be great.
Image of the laser cut piece is what I need, and the nomad file (so far) is where I’m at. I’m probably missing something stupid to invert what I want carved.
