will highlight the color and allow changing of the settings by using the scroll bars or 
highlighting out and typing in each setting.  It is possible to set one color at a time or 
click on additional colors to set more than one at a time. 
 
 

Power Setting 

 
Laser power is controlled by assigning the percentage of power from 0 - 100% to each 
color used in the graphic drawing.  Since the laser is proportionally pulsed,  this 
percentage represents how long the laser remains on for each laser pulse fired.  
Basically,  the power setting is directly related to how deep the engraving will be. 
 

Speed Setting 

 
This setting controls how fast the motion system moves in a percentage of the 
maximum speed of the system.  For example,  100% Speed is equivalent to 25 inches 
per second straight line velocity.  Therefore,  10% Speed is equal to 2.5 inches per 
second.  When engraving,  this is the rate in which the motion system moves back and 
forth.  When cutting, this is the speed of the straight lines.  If cutting curves or circles,  
the motion system automatically slows down.  For example,  there is no speed 
difference when cutting a circle at 50% or 100% Speed because curves will run slower 
than straight lines even if it is set to 100%.  Proportional pulsing of the laser will ensure 
that there is no difference in the depth of cut from straight lines to curves.  Power and 
speed work together in determining how deep the engraving will be.  Higher power 
settings and slower speeds will produce deeper engraving. 
 
 

PPI 

 
PPI stands for laser pulses per inch.  This setting determines how many laser pulses,  
per linear inch,  the laser system will fire.  Again,  since the laser system is 
proportionally pulsed,  all pulses will fire equally spaced from one to the next regardless 
of changes in Speed,  Power,  acceleration,  deceleration,  or the cutting of curves.  For 
example,  when setting the PPI to 500 and using a standard lens that has a laser spot 
size of seven thousandths of an inch,  significant pulse overlap will occur.  The laser 
system fires a laser pulse and  moves over two thousandths of an inch (that is 1 inch 
divided by 500).  It then fires the next pulse and so on,  overlapping the pulses 
significantly.  Lines are formed by pulsing the laser pulses so close together and slightly 
overlapping each other that it appears to be a continuous line.  Dot matrix printers work 
the same way except the laser system uses laser pulses instead of ink dots.  When 
engraving,  it is advisable to use a PPI setting of 500 or higher.  If using less, the image 
resolution of the engraving is reduced.  For cutting,  a PPI of 150 and above can be 
used.  Using less than 150 will result in the pulses being spread so far apart that they 
will not touch one another.  This is a good example on how to perforate paper.  
Increasing or decreasing the PPI setting has absolutely no effect on engraving speed.  
The laser must either fire more quickly or slowly.  Experiment with using different PPI 
settings on some scrap material when cutting or engraving and note the results.
