Setup:
Lightburn 1.3.01
xTool D1 20W
When engraving on 2-color acrylic, the amount of material that gets etched off from the laser is wider than the system recognizes. This results in the letters of the logo appearing to “bleed together”.
Does anyone know if there is a way to offset the laser from all edges of the image by 0.05mm (or another measurement) so that I can account for this?
Not saying this is a solution, but why did you choose Image mode rather than Fill?
My understanding of dithering is the intentional introduction of “noise” and is used when converting images to to a dot pattern the laser can reproduce. It seems to me you have a very clear, hard line graphic.
Then again, maybe I’m wrong. Again, not implying a solution. Just wondering.
Will - I’ve tried the image setting (the default when importing the file), and also tracing the image and using “fill”. Both styles had the same result.
I tweaked a couple items which helped me garner a better result:
Slowed down engraving speed to 40mm/s
Decreased engrave power to 25%
Turned on dot width recognition to 0.08mm
The combination of those three seemed to get me a much clearer line. I’m not convinced the dot width recognition made a significant contribution, but it didn’t hurt it either.
