I’ve got some images as svg, is it needed to export them to png to laser them or is it possible to laser a svg (because of quality)? If yes, what needs to be set to laser the whole svg (even filled objects)?
I just posted a white paper this morning that discusses how to optimize your laser for the smallest “dot” and convert to DPI. I did this for a 7W Diode laser, but the same method could be used regardless of the type of laser you have.
I found that matching the DPI interval to your max DPI of your laser will produce the best results because it will not skip image information if your DPI is too low, and won’t duplicate image information if it is set too high. I agree with other posters - your laser will never achieve 900 DPI no matter which laser you have.
The source image (your PNG) can be higher than you need, and that’s fine - it’s actually good to have about a 500 DPI source image or better, if you can, as it gives LightBurn more information to work with, and can help.
The output DPI is the more important one - that controls the dot spacing of what LightBurn sends to the laser. In LightBurn, DPI and Interval are just two ways to control the same property - IE, the spacing of the dots / lines that it sends to the laser. If you use too high a DPI value (or too low an interval) the lines end up overlapping, and it turns the shading into mush. This is really important for things like photographs with smooth shading, but much less of an issue for simpler stuff like the logo you posted.
