How does federate effect my engravings? 

Depending on the speed you will get different levels of darkness: 

SLOWER = DARKER 
FASTER = LIGHTER 

What power should the laser be set to? 

We recommend setting the laser to the 

manufacturer’s

 recommendation for the laser.  For our lasers it 

is what the driver was set to when you got your laser from us.  For the 2W kit it is 1amp.  For the 2.8W 
kit it is 1.5amps.  For the 3.8W kit it is 2.5amps. 

This is frustrating to get to work.  Why is this so difficult? 

This is an advanced method for engraving images and takes some time to master.  Mach 3 has a lot of 
settings and your CNC is probably different than ours, so you need to understand the differences by 
looking at the manual and figuring out what is needed for your machine.  It might take some time, but 
the process has been proven to work.  Be patient, read the instructions, and take breaks if you become 
frustrated.  If you need help, please give us an email at 

[email protected]

 and we 

will try and assist you.
