Running the System Step by Step 

 
 
 

 

 
 

Focusing Methods 

 
Before attempting to adjust the focal height,  first make sure that the table is down low enough 
to prevent the focus carriage from hitting into the piece of wood.  To adjust the table height,  use 
the  Z-axis  adjustment  knob.    Turning  the  knob  clockwise  brings  the  table  up  and  counter-
clockwise lowers it. 
 
With  the  top  door  still  open,      press  the  “Z  Setup”  button  on  the  control  panel  of  the  laser 
system.    You  will  see  the  focus  carriage  move  to  the  (1,1)  position  directly  over  the  piece  of 
wood.  Using the focus tool adjust the table until the proper focal height is achieved. 
 
 

 

 

WARNING:    Be  careful  not  to  position  the  tool  underneath  the  focus  lens  as  this  can 
damage the lens if the table is driven up into it. 

 
Sometimes  it  is  desirable  to  be  slightly  out  of  focus  when  engraving  or  cutting.    It  widens  the 
beam at the surface of the material to soften the image or create a wider cut line.  One complete 
turn of the Z axis adjustment knob moves the table either up or down .066 inches.
