GBR files

[MegaBlackJoe]

I am importing a gerber file at 0.1 resolution. I get these artifacts as shown on the screenshot. These should be circles and I can see random pixels added on top. Also some random pixels are added on traces. When I change the resolution to 0.05 the situation improves, but still some random pixels can be seen. 0.05 is a lot better but it also increases engraving time. I don't think such an accuracy is necessary, because most chinese lasers running a gbrl have a focal point that is larger than that. But still, if I don't adjust the resolution, artifacts will be transfered to the part. Is there anything that can be done here? It may not be just a GBR file issue, I have noticed the same when using images like bmp or png. Thank you.

Nottingham - I suspect it is the transparency laser. Try disabling it off before inverting.

Are you using the default Gerber import settings?

I just loaded your file and it looks smooth.

The vector format is converted to raster based on the resolution, but 0.1 should be acceptable.

Yes, I am using default settings. I have such a result (as shown on your screenshot) only if I use the resolution of 0.05 but when I use 0.1 resolution it's similar to my previous screenshot. Still even with the resolution of 0.05 you can see some random pixels. I have marked them yellow.

I used 0.1 also but yes if I screen capture and magnify I do see what you are talking about. I removed the aperture and the path is clean so it must be the radius on the joints, whenever you convert a vector to raster there will be artifacts. They should not cause any issue as they will be less than 100 microns in size.

All right, thank you, it explains everything.
