Hello Ger,
Yes, I had to slice the model, carve the edges then glue the parts like a puzzle. This was my first attempt and took forever, but I have learned a ton since then, and now things go much faster......machining that is. The slicing of the model and creation of the codes still take forever. Vetric has a software that will do this automatically, but it requires that I save all my files to stl, and I simply refuse. That makes for huge files, and hard for me to handle, so I still plug along.
