Hi , I used this setting and you can see the result
Its not an issue in the small scale, but here is the example in bigger scale.
I would like to optimize the movement, that the lines are simply cut first, horizontally , then vertically.
It looks like you’re filling an irregular outline with a regular grid, but the grid is made of small crosses. As a result, the path planner draws each cross individually.
Rather than that, create a large rectangular grid using lines, then use the outline path to select the only the part of the grid within its borders. The Boolean operations will get that done; watch the video to see an example of exactly what you need.
You can create the grid from two lines, one horizontal and one vertical, by duplicating them with the [Grid Array](https://docs.lightburnsoftware.com/Tools/ModifierTools.html#grid-array) tool at the proper spacing.
