My LightBurn program is not fill engraving correctly. Is there a setting that needs to be adjusted to remove the lines left in the engravings?
I ran two identical tests back to back. 1 in LightBurn and 1 in XCS and the LightBurn test has lines all throughout and is very dark, whereas the XCS test looks good.
LightBurn settings for the box with the cross… 60% Speed, 335mm/s Power, 160 LPI
Settings for the lines below… 60% Speed, 335mm/s Power, .5 Line Interval
Also, when engraving with Bi-Directional checked there is a very noticeable gap in the box with just the lines, when the should be evenly spaced just like the box next to it when bi-directional is unchecked.
Thank you in advance,

Your interval is way too high. The D1 specs state a laser spot size of .08 mm. That equals 317.5 LPI. You’re setting of 160 LPI would require a spot size of .16 mm. You’re skipping every other line at 160 LPI.
Based on your suggestion I changed the interval from 160 to 317.5 and reran the test, and there are still visible lines. They are very close together now but still visible to the naked eye.
I was told that increasing the LPI too much wasn’t good either. It was explained like mowing the lawn. You want to be right next to each other because when you start going over top of the other cut that’s where you get a burn issue.
Also I don’t know if you noticed in the first picture I posted, it shows the line appears to skip in the area below the settings information when bi-directional is checked but the line spacing is unformal when it is unchecked. I ran that test based on LightBurns recommendations for the scanning offset adjustment hoping that that could have been my problem.
That’s true, but it sounds like you’re not there yet if you still have visible spacing. That’s why we experiment with settings on each new material until we get it dialed in.
It appears that you have a slight scan offset, but it’s hard to tell from the picture. Something about how you put the picture in your post won’t allow me to click on it and blow it up. Nevertheless, I don’t have any thoughts about the line spacing issue with bidirectional. I see it, but don’t know why.
