Many dots on Laser Engraved Wood

[adonis94]

Hello Everyone!
I'm a novice, practically a noob, in doing laser work as I've just started a month ago. I'm still experimenting with all the different settings in cutting and engraving.

I notice that when it comes to engraving on wood, my engraved pieces seem to be littered with dots (uploaded pictures of my results in this post) instead of being smoothly engraved like what I see in videos online.

My images are processed via Image R with a DPI of around 300. I'm using Inkscape to generate the Gcode which my laser machine can read. I'm also testing it on normal plywood.

Does anyone know why this is happening and how I can make my engravings smooth?



Thanks a lot!

If you're starting with bitmap art, this is to be expected. A bitmap is a series of dots, or pixels; the software has no reason to connect any of them. If you want lines instead of dots, you need to start with vector art, not bitmaps.

Vector art isn’t a real thing. Sure it’s a vector drawing like a DXF outline and art I guess but it won’t allow you to engrave a photo.
Photos are raster scanned images. They are made up of dots and dashes like a halftone image in a newspaper. The image can be adjusted using software. I’d recommend trying Lightburn.

Thanks for your reply and your advice.

If my aim is to be able to engrave smooth images onto wood using source photos taken via smartphone cameras, is there any way to do it?

Thanks for replying and your recommendation.

I'll play around with the free trial and see where it gets me.

Cheers!
