wow that turned out great was it one pass?
I didn’t set it for multiple passes, but the “deep engrave” option does multiple passes, so…yes and no?
once it warms up a bit and my windows are not frozen shut. playing around with some acrylic is now on the list.
Where do you get a “deep engrave” setting? I don’t see that, first time I’ve seen it mentioned.
(I looked in each of them and don’t see anything beyond “dots”, “patterns”, or “vary power”. Also checked Manual settings…)
Just wow!
Masked or no? Did you have to clean it after or was this as is?
I have been doing that with wood for a while but not thought of dark acrylic, That looks fantastic!
Yeah, it just showed up when I went to do this one. I figured it was triggered by the type of graphic in the job.
No masking. I scrubbed it under the faucet with a nail brush. I think some polish would bring back the shine, but I don’t have any. I’m going to try some toothpaste on it and see if that will do anything.
That is interesting. I see an additional “Photo” setting as well.
Edit - ok, it shows up with “Thick” PG acrylic. Uses same settings as 3D Engrave, but 2 passes.
It can tell if the image is a proper depth map? I have always used settings derived from tests.
It’s 'cause I’m special.
First I have heard of it also. I don’t recall any announcement of new options, so… an Easter egg?
I insist on believing it’s because I’m special.
That too (of course), but it’s also material triggered. It doesn’t show up for plywoods, because those don’t look good with a 3D engrave. (Rasters only.)
It’s always been there - but only on the ‘thick’ materials and maybe only on the Acrylic. I have been using it since I got the machine (2 years ago) though I also like to defocus a little for the second pass.
Well, dang. The joy we miss when we don’t have all the PG materials!
I’ve pulled up several projects that I engrave pretty deeply, switched the material to thick acrylic, and still don’t have the deep 3d engrave option…hmmmm
edit: I found one that works… not all vector images gave me the option, but apparently, some do. Found two, actually, both multi-step engraves, but all are vector. Some, like the aztec calendars, still have a mixture of vector and raster elements, so it doesn’t give you the deep engrave option.
3D doesn’t work with vectors because it uses vari-power. Vari-power reads the grayscale value of the pixel and modulates the power accordingly — since vectors (that work with the GF) are only one single color (no vector gradients allowed), there is no differing power to figure out, so no variable-depth engraving.
