CROSSHAIR LASER SIGHTS
Without something like the LightBurn camera,
laser crosshairs to visually display where the beam
will hit are a great aid in positioning material.

AIR ASSIST HEAD
This device replaces the stock head (or just the
bottom of it), allowing a source of compressed
air to shoot down along the laser beam. This
suppresses flames and the resulting char that
the laser causes with many materials.

AIRBRUSH COMPRESSOR
For air, there are a variety of heavy duty aquarium
pumps and other options. I bought an airbrush
compressor since it is also useful for painting.

• Recommendation: MUST DO (some solution
if using air-assist)

EXHAUST SYSTEM
The stock exhaust fan is just barely able to
clear smoke and fumes from the laser. A more
powerful fan is a big win to keep from stinking
up your shop and accumulating residue on your
mirrors and lens.

Z-HEIGHT LAB JACK
By removing the static deck provided with the
K40, you can put a height-adjustable table in its
place. This is important because the focal point
of the laser never changes; instead, you move the
material up and down to accommodate different
thicknesses. This jack’s table surface is only
4"×4", so it needs something on top of it. It’s easy
to accidentally tilt the top, so use a level to make
sure it’s true to the laser’s X and Y axes.

LENS
This is a drop-in replacement for the stock focus
lens that has better coatings and performance.
