temperatures where the water can freeze overnight, there is a high likelihood that
the expanded frozen water will break the laser tube.
Q: Can I use a different Focal Length than the included 50.8mm focal length?
A: All focal lenses must be 20mm in diameter to fit the laser tube assembly. The
shortest focal length that can be used is the 50.8mm, constraint by the laser
assembly mounting tube. A longer focal length can be used by removing the
removable bottom of the PL1220 and resting the machine on riser blocks to
accommodate the larger focal spacing needed.
Q: What type of lubricant should I use for the linear bearings?
A: White lithium (PTFE) grease is recommended.
Q: Do I need to use a Fume Extractor with a CO2 laser cutting machine?
A: You must vent the machine to a safe location that will not harm yourself as the
operator or any bystanders. This is most easily done with the use of a fume
extractor machine. The use of a Fume Extractor is beneficial to the safety of the
operator and bystanders as it filters the harmful byproduct away. This does not
make it OK to use harmful materials as the fumes must still travel through the
venting and parts of the machine that could be irreversible damaged.

WARNING!
It is the operators responsibility to understand the material properties and safety precautions peculiar to those
materials. The Material Saftey Data Sheet (MSDS) will always be available through the material manufacture.
NOTICE!
UNITS - These results were achieved using metric units – mm/s. Make sure that these settings are not
inputted as inch/s. The max power is 100%. The max speed is 500mm/s. The default interval is 0.1mm.
THIS CHART MAY NOT BE ACCURATE! Because every laser machine is unique, it is difficult to produce a finite
cut chart for reference. This chart should be used as a baseline for the operator to adjust the RDWorks
parameters to perform a proper cut or engraving on the work material. It is highly advised that the operator save
working parameters in the RDWorks Parameter Library. Feedback and suggestions will help us to further
develop these parameters and are highly appreciated. Please email us at manuals@lagunatools.com
MULTIPLE PASSES - Start with low settings and gradually increase them. If the workpiece does not move, the
work file can be run multiple times to complete a cut or further detail an engraving. This strategy can be used to
cut thicker workpieces.
Use the following tables and select the material closest in material properties to the
workpiece to be cut or engraved.

There are commonly two types of acrylic. Casted acrylic produces a frosted-look engraving. Extruded Acrylic
(the cheaper of the two) is best for cutting and produces a clear engraving.
