So I’m trying to justify buying a laser for my machine, and am deep in the creative space of “what could I do with it?”.
Can a laser be used to engrave on an existing 3D surface? I would want to make a 3D carve, for example, and then use the laser to engrave lines or text across the top. I would zero the z axis to use the focal point of the laser just like a tool to follow the surface. I imagine the software would need to generate a 3D path for the “laser tool” plus a PWM output for controlling the laser intensity. Is there software that makes this possible?
I use Fusion360 for all my modeling and CAM needs. I can easily draw the 3D paths/text, but I’m not sure about processing that into a Gcode output. Has anyone done this before? My google-fu has failed to find a good example.
I have a laser on the way and was curious about the same thing. If you are good with a 43 min video, this one has a lot of detailed info on Make 3d model in Fusion > import in to VCarve Pro > toolpath w Vectric laser module > laser engrave on a wooden spoon. Not sure if it’s the easiest or fastest way out there, but sounds similar to what @EdwoodCrafting did
