you're right, this would be too fine for a simple cyclone like that. A really good cyclone needs to be MUCH longer/taller to work properly for stuff like this.
I feel like you did the engraving in reverse of how it should have been. The white areas should have been the lowest points in the engraving. That would make the 3d effect of the skull coming out vs leaving a depression. But then ur back to having to frame it somehow, i dunno, it just looks odd to me and not really what i was expecting.
Is there a tool to invert the depth map? Seems like the eye sockets and edges of the skull should be the deepest deboss instead of the highest. Or maybe like you showed toward the end that the true depth isn't that noticeable?
For the metal dust issue, maybe a water trap? Exhaust from the laser goes into a 5 gallon bucket, may 1-2 inches below the surface of the water. Vacuum pulls from above the water level, should trap a huge portion of the dust.
I really want to know what's stopping these from just doing 10-30mm depth cuts, given that you mentioned a 2.56mm depth limit. I mean, beside grayscale bitdepth limit, which sounds like a solvable issue.
Have you considered filtering the exhaust through water, conceptually the same thing as a bong? The exhaust cools as it bubbles up while the iron particulates precipitate to the bottom of the vessel.
I'd love to see how this would work for some pseudo "machining". Cutting out some linkages and gears and whatnot. How much precision you can get, how much kerf, surface finish, how much time it takes when you're just following a vector rather than filling in a surface. Could potentially be a practical application for small and otherwise difficult to cut out geometry.
Only CO2 lasers can cut clear acrylic. Diodes can't and fibers can't. Fiber is for engraving metal, diode is for most non-transparent organics (some plastics, woods, leathers, etc) and CO2 is for everything a diode can do, but with clear arylic.
I find "AI" Being slapped onto everything hilarious (AI thermal paste anyone?). Maybe somehow it's actually using anything I'd call AI but this seems like pretty traditional image conversion operations (the depth map). I could be convinced you could get similar results with any photo editing tool or a python script. Also, funny moment at 11:50 if you're child minded with the googly eyes moving around as the skull gets it's face lasered.
This is Embossing not Engraving. Image could have been inverted before creating DM. No reason to slow things down with 300 lpc; the image does not have enough detail to warrant that. There are ways to filter out a lot of that stuff before it reaches xTool overpriced filters. And just because the head moves down .01mm per layer doesn't mean that much material was removed or that you will achieve the depth you think. That is material and settings dependent.
I bet if you put those same filters in a smoker's house, they wouldn't look like that after 10 hours. Maybe 10 days. But more likely a few weeks. So yeah, that's some stuff in the air. Not sure how I feel about that. I mean, China wouldn't sell you something that could hurt you, now would they? /s
Would a magnet be useful to catch some/any of the iron particles to act as sort of a pre pre filter?
or one of those centrifugal things that stuffmadehere added to his cnc mill's exhaust, but the metal dust might be too fine for mechanical solutions
Yeah, a magnet could work to catch some of the particles.

It looks sick.

Do the exact same test with the "NEW" filter and let's compare!!!

I would rather use my CNC. But cool that you can do something like this at all.
Can you try if you can post process a 3d print, adding tiny details on the surface.

engraving brain folds around the whole body of the bot would be sick but i shudder to think of the time it would take
Ha, that would be horrible.
I wonder if a water trap air filter would do a good job?
I really want to know what's stopping these from just doing 10-30mm depth cuts, given that you mentioned a 2.56mm depth limit. I mean, beside grayscale bitdepth limit, which sounds like a solvable issue.
Yeah, in theory you could just manually refocus it deeper and keep going.

Maybe next time add a green filter or something during the laser timelapse, easier on the eye.
im curious, can the fiber laser cut clear acrylic? cant find any info about it
it would be a much better space efficient laser cutter for acrylic if possible
Only CO2 lasers can cut clear acrylic. Diodes can't and fibers can't. Fiber is for engraving metal, diode is for most non-transparent organics (some plastics, woods, leathers, etc) and CO2 is for everything a diode can do, but with clear arylic.
Yeah, understood. But only CO2 can cut clear acrylic. Cloudray has something in this general form factor that's a CO2 laser.
@RobertCowanDIY Out of interest, why can't a fibre laser do clear acrylic, but can do metal when a CO2 can do the opposite.

Yeah, I need a fiber laser.
You do!
