Focusing
The laser must always be in focus when in operation. Not only will you not have full power but
low power out of focus laser beams will burn or start fires instead of cutting through materials.
Focusing the 24x18 is quick and easy. Your laser included a focus ruler sized for the included 2-
inch focal length lens. To focus for engraving or cutting, simply place the ruler on the top of
the engraving plane and jog the Z table up or down until the small notch rests evenly with the
flange of the air nozzle (Figure 15).
Figure 15 - Using the Focus Ruler
As an alternative to the focus ruler, you can use the included autofocus mechanism. FSLaser
recommends using the focus ruler to achieve best results. Note that for thin or delicate
materials you should always use the focus ruler.
