Cutting in lightburn

I’m playing around with lightburn for engraving. What I can’t seem to find is the step down for each pass when I’m trying to cut out my engraving. Is that a thing or do I just have it go over the same spot and hope it eventually cuts through?

Probably a better question for the Lightburn forum, or the documentation:
