Focus test without z axis

“You need a controlled Z for it to work”

How does the focus test work?

I saw a reference to a new feature in LB and also located it in the menu system. The online docs have not yet been updated to include the focus test option and a determined search of the system doesn’t say much either. What might one expect if one selected the focus test? Would the laser immediately begin to fire out a pattern of a certain size? What preparation should be made for selecting this task?
