I’ll be updating this with a full post soon, as well as contact support, but for now, just keep this in mind:
Just because you’ve been able to easily cut through a .25 inch piece of Maple from Home Depot, that doesn’t mean that you will be able to also easily cut through a thinner piece of Maple from a very old, very solid tree!
I put this sucker through a lot of passes, too…maybe I should have changed the focus depth each time, hmmm…
Wow. Great advice. Looks like a case of variable density, where the edges on either side of the dark/light wood transition are much harder to cut through. Not really sure how one could compensate for that - well, I can think of lots of ideas for how to do it, but I doubt the Glowforge head has an x-ray source and matching receiver in the bed
Nice work! I see some figure in the wood you were cutting - that can dramatically increase the density and, as a result, how hard it is to cut through.
I like it! For mission critical jobs, a first raster-like pass over the whole surface with the ultrasonic head could be done, which would build a power/speed modifier map for subsequent cuts/engraves.
Would take a looooong time, but if it’s important enough to get it perfect, might be worth the wait. You wouldn’t have to closely watch the machine during the first phase.
