The led laser is just strapped to the plasma gantry so it's only 2 axis. Can I burn something on like that...as long as it fits under the gantry sure. It may not be 100% correct though since the beam wouldnt be perpendicular to the work piece all the time.
I'm a cad guy by trade so if I can draw it I can cut/burn it within reason. The plasma table is a bit temperamental with small detail work... The led laser I can get pencil line thickness
The firepits are made from a flat pattern...I do all the cutting g then bend them into shape...that's what allows me to do the fancy designs on what is essentially half a geodesic dome
