I have done lots of trial and error and am finally able to cut and score my pet stud earrings successfully! I’m not sure if there is anything that can be done about this, but the sides of the earrings are very charred, they are completely black. I am wondering if there is anything I can do to make the sides show the different shades of the brown wood instead of looking so charred.
The wood I am using is .125" bamboo wood from inventables, and then for the settings I chose on the Glowforge are:
Thin Maple Veneer
For the most part the act of cutting through the wood with heat will char what does not evaporate. That part is pretty much unavoidable. The char is not as strong as wood so some can be removed with a tight wire brush and a bit of sanding, though that small may be difficult and time consuming, Another means is bleach or ammonia (but not both!) that could lighten the burn. Another alternative is a tumbler with salt or fine media. I bought one to use with salt but the salt has some very big limitations on what I was doing though it might benefit the size stuff you are doing.
The things you are doing could benefit greatly from Proofgrade maple as the surface is finished and it is thin enough to have the dark sides be less obtrusive, It should also be stronger in those sizes than bamboo.
Are those the barest minimum settings you can use to cut through the bamboo? If you can dial back at all, it would help. You can enter the settings manually. But my experience with bamboo (minimal, granted) wasn’t great. I think I used 200/90 for bamboo.
I’ve cut a lot of hard maple (wood, not plywood) lately and using the same settings the edges vary from a warm brown to a darker brown. So even using the same wood, from the same board, will give you varying shades of brown.
The color of the edges varies with settings, so fiddle with those, but even with the same settings expect some variation.
