The first time I tried Dither mode, I got regularly spaced square “dots”, creating an image that looked better as you got farther away from it. It wasn’t what I expected but I was pleased, especially since it was done on a wine barrel top that would mostly be seen from 3-4’ away. I’ve since used Dither on other projects, but have not gotten those “dots” again. What am I not doing right?
Dithering creates the dots.
I realize that Dither created the dots, but Ive tried it several times since, with constant power turned off, and haven’t been able to replicate the image. It might not matter-the first image I did was from a color photo, the others from B&W photos
There are settings to assist you with finding the right output you’re looking to achieve. Here, I highlight.
LightBurn offers an ‘Image Adjustment’ tool to assist with these options. You can try different settings, and review the results directly on-screen. Once you have a setting you like for a particular use, you can save them as a ‘Preset’ for quick recall later.
These sections, along with the entire documentation, are worth review.
Crimeny! you wrote Doctoral thesis for me. Thank you very much!

Welcome, and hope I didn’t overwhelm. There are a bunch of great options for image production, so wanted to provide a solid overview and offer links for greater details. 
This only 6X6 and etched on western red cedar, not the best wood for this, but this particular wood has special meaning, so it’ll have to do.

Looks like there is some noise (producing lines) in this image. Did you dither this using some other software prior to importing into LightBurn? If you did, you might want to try the option to ‘Pass-through’, or tell LightBurn to not touch the original image and produce without further modification.
If you post what you are starting with, we may have additional ideas to help you get what you want.
The noise is just the grain in the cedar. I have much better luck with Oak, which is what I’m using most of the time
Most of my work will be inscribing logos on wine barrel tops for wineries. I create outdoor furniture using wine barrel staves, including chairs and tables, as well as trays and lazy Susans. This one was quite by accident when I got the dots without knowing how I did it.

the grain of the wood shows through here as well. Future projects will be done a little differently-wet the wood, let it dry, then sand at 220 grit. The grain will be more receptive to engraving I believe. At any rate, this stuff is way different than what Im used to doing with wood.
