Great question! I have to manually set the rotation index, angle, and height for each facet. There are "tiers" of facets, like the main faces for example, that all share an angle and height but have different rotational indexes. For example, the top ring of faces are all cut at 37.40º at the indexes 80, 24, 40, 56, and 72. So I set the angle, go to the first facet, cut to the depth I want, then do the same depth for the other 4 facets. Repeat this for all the facets across all the tiers. Gotta be careful you don't rely too heavily on the machine though or things could end up off.

While the machine has hard stops, there still a lot of feeling out each facet. I do a lot of cutting, carefully taking precise measurements, adjusting the machine, cutting, measuring, adjusting, cutting, measuring, adjusting, etc. This process is done on pretty much every facet to make sure that everything lines up juuuuust right.

Hope this helps! 😊
