It is important to note that there are several factors that affect the results of your machine’s cutting and engraving. These factors include:

● Making sure the laser tube is properly leveled

● Having mirrors #1 and #2 properly aligned and firing towards the center

● Making sure the laser beam is exiting the nozzle towards the center (The level of the Laser Head and Mirror #3 can be adjusted if needed)

● Making sure the focusing of the laser is adequate (you should be getting a small sharp dot between .1mm .3mm in diameter) on your material after you pulse the machine at 15% power

● Proper air assist (lower PSI between 8-13 is recommended for engraving while a 20+ PSI is recommended for more efficient cuts)

● Using a water chiller set at around (63-68F or 17-19C) also helps in maximizing efficiency, as it will maintain the laser tube in an adequate cool temperature producing a more efficient laser beam

● The focal length of the focal lens: A 1.5” focal length lens will allow better engraving quality, A 2” focal length lens will allow good engraving and cutting, 3” and 4” focal length lens are better suited for cutting thicker materials

● Proper software settings
