Bamboo Cutting Board

Did this tonight…

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 :proofgrade: 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.

Just gotta figure out how to translate that into figures I can use on my machine…lol

I must say, even as a complete noob laser owner, I feel ridiculous saying 1000. I cringe not being able to apply a real-world unit of measure.

1,000 = 335ipm :slight_smile:

@Tom_A if you want to experiment, Lowe’s Home Improvement has 4" x 4" x 0.420" thick solid bamboo flooring sample chips for 25 cents each. Pick up a dozen, have some fun :slight_smile:

I tried cutting through one and that was a big negatory… after 12 passes at full tilt and getting about 1/8" into it, I got bored with the test. LOL.

Yeah still not useful…lol
Universals have 0-100% for power and speed
Then dpi and ppi

Wow. Yeah I really should. My Wife picked up these boards yesterday and I had no idea they were bamboo until earlier tonight. I can’t believe you couldn’t get through at 12 passes?! Geez!

Yeah, I even called my dad because he’s the woodworker in the family.

His response: “Yeah, there’s a reason they’re making cutting boards out of it.”

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!

My only, “Oh sh*te” moment with the GF so far was a bamboo cutting board. Lets just say it got a bit hot :grimacing:

Interesting thing is that bamboo isn’t really a traditional wood…its a reed. And those pieces are layered together. The hardness seems to come from the long fibers…reminds me of celery…lol

I assumed as much. That’s why I figured going with the settings of :proofgrade: Thick Maple Ply would be my best bet.

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.

For a comparison to other familiar woods, poplar is about 400 and balsa 100.

I just did the cutting boards recommended from the materials supply thread, and while a speed of 1000 is great, a power of 100 is a bit much. I had my best results with a power of 80. Otherwise, my settings were those that were indicated in the first thread.

Here is my blog post of the cutting in action.

Thanks for the help with the settings! I just did my own bamboo cutting board project for a friend’s company using your settings and it worked great.

Those are OUTSTANDING results. :grin:

Thanks! I tried it on some larger boards and got even better results. This one turned out really nice!

Was that using the 1000/100/340 settings?

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?
