Not for this case, One thing you need to remember when cutting fonts - you need special stencil fonts.
I wanted to show you the result of your file. Just a testcut but it looks very good.
Thanks for your help

BTW and In regards to your profile picture,
For many years now I volunteer at the mediterranean sea turtles conservation at the local National Parks and Nature Reserves.
Some years ago I was at the island of Zakynthos. At the southern part of the Island there is a big part of the beach reserved for seaturtles. They can lay their eggs in all peace and quite.
Just made some of these.
remixed a 3D STL model from thingiverse, converted it to 2D raster, then traced it in lightburn and added a turtle art shape, engraved and cut filter holes, and there you have it.
You can get a cheat-sheet for the commands by pointing your mouse at the ‘Edit Nodes’ button and pressing the F1 key (help). This works for most of the controls on the main LightBurn window.
