And the question of settings came up. So here’s the scoop…
This board was .4" thick bamboo. I hadn’t used it before and I didn’t do any tests. Usually I test new materials rather extensively. But I didn’t have any to spare, so… I figured I’d base my settings on Thick Maple Ply. As such, I used 1000/100/340. It turned out just the way I wanted it… Great contrast, yet not too deep.
The Janka hardness test measures the resistance of a sample of wood to denting and wear. It measures the force required to embed an 11.28 millimetres (0.444 in) diameter steel ball halfway into a sample of wood. This method leaves a hemispherical indentation with an area of 200 mm2.
While that puts bamboo around 1300-1400, similar to oak. Lots of references say that strand woven bamboo is usually between 4000-5000!
That’s interesting 'cause this sample piece I have is darn near impenetrable. Yes there was a small flame but still way less than with paper masking on non-PG acrylic. I thought I’d have problems but I had to give it full power and two passes to engrave. My first test using PG settings barely even tagged it.
My bet is since this was a piece of flooring, it’s probably made with a really tough binding resin and under high pressure to compact the strand fibers and make it solid as a rock.
Great looking results! Thanks for sharing. While on the topic of settings, I’m wondering where to find the pre-selected settings when using a product on the GFUI. For example, if I choose “Medium Maple Plywood” where can I see the settings used for this product?
