Hey Everyone, newbie to laser engraving/LightBurn here. I am having issues with some of my burns going out of the bounds of the image I am trying to engrave:
The top was started with Jarvis image mode, which over burned as you can see at the bottom of that coaster (the pure white was intentional as I restarted the burn after changing it to Grayscale and inverting the image). The lines that extend beyond the picture are what I’m having an issue with getting rid of. The way I got rid of most of them was to change to Grayscale and drop the minimum power to 0%, which is how the bottom coaster was printed.
In the preview mode, all of the traversal moves are where the extra lines show up:
I also checked the original image for artifacts and can’t see any (background filled blue to double check for artifacts.) I applied the alpha layer and exported as PNG to keep the alpha channel, but it doesn’t seem to have made a difference.
I get it with all images, but not vector fills. Vector fills have been great so far!
Looks like my .lbrn file is too large to upload directly, I’m assuming the picture is just very big. I have uploaded it here, unfortunately it is through mega so I know it may look a bit suspect, I can assure you it is safe.
If you’re not getting it with vector fills then I have to think there’s something going on with images.
However, if I look at your .lbrn file I don’t see anything wrong with it.
I’ve modded your file and added a mask around the image. Can you try burning this and seeing if you get any issues? You can burn to anything, doesn’t have to be slate.
I will look into seeing how outdated my firmware is and hit up Ortur Support to see if they have a solution. It also looks like you sent that from LightBurn 1.3, I’m on 1.2.04, maybe that could be something, I’m not sure hahah. I appreciate the help regardless!
