I am trying to engrave a wine glass. I have the roller style rotary. How do I adjust settings for the different heights of the glass? It starts out great as that is where it is focused, but as i continue on, it stops showing up since it is farther away. I am pretty new so hopefully this makes sense as I don’t know all the right lingo yet!
You can compensate some of that with a longer focal length lens… find the best final distance and position in order to make year if the whole length of usable laser.
If the glass or tumbler is sloped consistently, simply raise one end of the rotary to create a consistently flat / focused target.
