Exactly that yes, if you want to laser thick foam or engrave a deep box you can drop the table. Some machines also have a fixed focus lens so you use the bed to focus the laser at the right height. My laser has an adjustable head but the table will be handy for larger items.

I am trying to simplify the z-axis/table cause the normal way of doing it looks complicated. Google it to see what I mean. Mine is more like a knee mill, I plan to use a car sissor jack to move the knee/table.
