People love these—as do I. An impressive demonstration of Glowforge precision.
Adjust the size as you see fit.
Cuts in ~10 minutes when set for a ~3-inch diameter.
I tend to use PG basswood because I can sand out the small amount of scorching that remains on the topside after the paper backing is removed. PG draft board, coated with polyurethane spay after cutting, works well too.
Amazing, and as you say, shows how precise the GF can be.
Did you make any particular ordering of the cuts to avoid the build up of heat at any point, to avoid scorching, or let it cut around the natural order of the piercing ?
John Brooker, I just let Glowforge decide, although I put the outline cutout last. It’s fascinating to watch. Can’t figure out how Glowforge solves the NP-complete “Traveling Salesman” problem for this, but I’d have to say that it does it well—and quickly.
I think this is taxing the minds of a lot of us.
I did suspect that having finished one cut, it then proceeded to the nearest ‘first node’ for a subsequent cut. But someone has noted somewhere that it does a different order for a repeat of the same project, so that rather knocks that out of court.
