Crating square around the logo

[John4 (John)]

Hi I’m a LightBurn user and learn how to use it via trial & error. Need some advice please.
I created a square around a product name and try to print it on Neje Master 2 20 laser engraver. It’ll print but instead of getting a square border around the name I get a dark square. How do I change this to get a square border. Thank you

Or just change the Square to Line and not scan, depending on if the box is creating the scan image inside it.

@John4, this is worth review to help in understanding how LightBurn uses shape boundaries to determine what to fill.

How do I invert (negate) a vector engraving?

The inner ring of the O toggles the fill. If you add another shape (like a square) outside it, it negates the whole thing: [image] And a slightly different example, this time done by changing the outer line around the design to a ‘Line’, instead of leaving it as part of the Fill layer: [image] In the case above, the design alr…

It sounds like you have selected FILL instead of line. If you select the square border only, then choose line, set your power & speed levels, you should get a line only.

Thank you Frederick. I got it working now. Great.
