Fix so it burns like the picture

LightBurn Software Questions
1

I am trying to get my lase to print looking like on the left. But When I go to preview this is what I see.

Then I go to adjust and it is a lot of grainy images. I am sure I am missing a setting somewhere Just have to find that somewhere.

Thanks in advance for any help

Although it’s not directly related to the images, the laser speed is set to inch/min with a numeric value commonly used for mm/min:

  • 8000 inch/min is impossibly fast
  • 8000 mm/min will be closer to the goal

You can select the units in Laser Tools → Device Settings:

Other folks with more experience in sorting out images will likely stop by in a while …

What I’ve found after about 5 or 6 years of using Lightburn, that most people have an issue understanding what the preview is showing you or actually does.

Neither Lightburn or your machine knows what you’re going to lase or the type of laser. Since the effect from lasing changes with materials and type of laser, it can’t possibly even make a guess of the damage it will do.

For example, if you wanted to engrave a piece of clear acrylic with a visible light laser, you won’t effect the media and it won’t mark or damage it, but it will still show as it is in the preview.

What preview shows, is where the machine will lase. You can also zoom into the preview screen. If you computer screen is smaller, there is only so much resolution. Might try that and see if the results makes more sense to you.

As a suggestion, might want to change from grayscale to some type of dither in your photo. This is much the same as a printing press, where they photograph it though grayscale sheet. This changes the dot size. More dot’s darker color.

You laser does it’s best when grayscale range isn’t involved, it’s just marking black areas. A dither would help you get going better than a grayscale.

Doing photographs using a laser is one of the most difficult things to do.

Good luck.

This is only a preview, you have to test and find the settings sweet spot for your images/material.

To waste less material, you can draw a square in a area of the image that ≈represent the gray scale. After select the square and the image then right-click and Crop image.
