I posted previously about etching a detailed, small design on cast acrylic. I eventually found something suitable thanks to off-focusing, but not quite the quality I had on an Epilog/Universal. I have another small-detailed design for a different material and can’t seem to meet my quality requirements.
I’ve troubleshooted raster quality for hours, it seems like the GF doesn’t have the raster quality of other machines I’ve used I hope it’s just some settings I can toggle to fix, but it is looking bleak.
Don’t give up. You’ll get a response that will guide you. I haven’t focused on that area, but I have created sharp edges in plastic, so I’m a bit surprised at your trouble getting detail. Sorry that I don’t have your answer.
Engraving some wooden hangers that have a curve in them, I experienced a similar look to your efforts due to the target surface being slightly below the focus of the beam.
When the surface was correctly in focus the details were razor sharp.
Got a picture of an attempt that is correctly focused?
One of the logos in the included pic was correctly focused at 0.125". The material does feel slightly thicker than the cast acrylic, but I don’t have a caliper to check (and the manufacturer says is 1/8")
When you’re working at those really small sizes, make sure you have a high resolution raster file. You can tell a lot of difference between 300, 600, and 1200 DPI. Your rasters look like 300 DPI or less.
Also, never score on the 2 tone acrylics. Score and Cut are equivalent.
If you meant DPI: my files are top-quality. I can zoom in and see everything super crisp in the .ai and .pdf formats. (For .svg it was distorted, so I stopped using that). For example this is 6400% zoom (still no pixelation, so I assume the PDF preserved the vector formatting)
I recall a bug where a rotated raster graphic will go garbage in the GFUI.
But it doesn’t happen in Corel so I don’t have the details. I think it has to do with the source program maintaining the original position and modifying its attributes with a rotation value that the GFUI doesn’t handle well. I believe the solution was to copy or resample it and paste the result (& delete the original) before saving and loading into the GFUI.
Nope, didn’t rotate it. This is at like maximum zoom in (1000%), the image is really tiny. There’s not really a good feel for it in the images, but if you zoomed in 1000% on your GFUI is everything crystal clear? Maybe I should try another browser (using Chrome on Windows 10)
I haven’t tried it yet, but it should engrave fine. I separated the colors just because. No real need. I think the biggest change other than grouping by colors was making a compound path out of the graphic inside the box.
