Is it possible to turn repeating patterns into paths?

Hiya

I have created a repeating pattern in Illustrator, using - Pattern - Make - then saving it as a swatch, I create a square and fill the pattern in the square. I am trying to export this to use it in my laser engraving software called lightburn so I can laser the pattern onto some square coasters.

Here is the pattern:-

Once I import it into Lightburn I only get the square outline with no pattern inside, it looks like this:-

I have tried exporting it as an illustrator file and also as an SVG and get the same result. My knowledge of Illustrator is very limited, so I don't know if what I am trying to achieve is possible or not.

If there is a way to turn the repeating pattern into paths so I can export it and use it in the Lightburn software to engrave that would be great. I would be be very greatful for any help or advice.

Thank you

Ben
