A question about adjusting laser focus with each pass

Has anyone ever tried to adjust the a laser’s focus with each pass to cut further down the same way a 3D printer adjusts its z height to print the next layers? I’m very nearly sure that someone out there has had to try this at one point or another.

Im assuming that a laser can only cut so deep deep as it cuts downward, it loses it’s focus. So constantly adjusting the focus has to allow someone to cut deeper and deeper right?

This is a common procedure. Look for “Z step per pass” in cut settings if you have Z enabled in Device Settings.

Ahhh. Maybe ill design another machine down the road that will allow something like that. Thats awesome thanks.
