Hey all - got my laser up and running today. Initially, it went well but then I started having an issue where the laser began firing several horizontal lines as opposed to a small circle (see photos). Any ideas?

Is your laser too far from the work piece?

The laser is way too far from the work piece. It should be 1/8” away from the bottom of the shroud. There’s a focus piece in the box.

Thanks. I used the focus piece when setting Z zero but I thought initially when trying to find X and y zero I’d need the laser elevated a bit to be able to see the pin point laser strike?
