Line 240:
=== Lens Types ===
We have 2" (default) and 4" focal length lenses.
* The 2" lens is our go to for almost every job. Good compromise between engraving and cutting.
** Our height guage is for the 2" lens, same with the smaller aperture conical nozzle. Make sure you're using these with the 2" lens.
* The 4" lens can be used for tall or thick items (ex: foam). Reduced energy density.
** When using the 4" lens you'll have to use calipers to add 2" to the height gauge (for a total of 4") and effectively hack your own.
** You '''must''' swap the conical nozzle for the one with large aperture to use the 4" lens, otherwise the laser beam will not come out of it!
