So, I am trying to do a relief of Mt ST Helens. Got to watch your board depth
I like the use of the cheatsheet painters tape
How did you generate your heightmap, and what did you use to generate your g-code?
I went to: https://touchterrain.geol.iastate.edu/ and isolated the area I wanted then downloaded the area that included both Mt St Helens and Spirit Lake. Then export it as an STL file. Set your work piece size in CAMLAB and then import it. The picture is the 1/4" End Mill rough out. follow this with 1/8" Ball Mill relief cut gcode.
Yeah, I have to remember the approximate RPM somehow
