I made keychains for all the adults attending a gathering last weekend. Afterward, I wished I had also made them for the teenagers that tagged along, so I got addresses from their parents and made a few more for them. I’m using a different board of the maple hardwood, but exactly the same settings.
Hm. I cleaning certainly cannot hurt, and I will do that. But I don’t think anything was printed with the GF in between these two pieces, and that seems like a big change for two consecutive cuts. It does look like the maple on the right is a little darker, and I don’t know whether that changes the way it cuts at all.
I had put it down to recent high humidity here in San Diego—but maybe not? I cut something from proof grade Medium Draftboard two days ago (using the automatic settings) and the laser failed to cut through the bottom paper backing completely. That has NEVER been a problem before—and I’ve cut a LOT of Medium Draftboard. I’ll guess try cleaning everything in the Glowforge laser path.
I’m having similar issues with cutting. It takes 3 cuts now even when using GF material. I have cleaned and cleaned and cleaned and it still hasn’t improved._
You should probably open a Support ticket for that.
But, if it’s taking 3 cuts - something is likely extremely dirty (but you’ve cleaned) - so aside from the dirty, it’s very possible you put the lens in backwards.
