Please keep in mind that the numbers are for the distance from the lens to the object, not the lens to the
workspace. If switching to a larger object then the stage needs to be adjusted accordingly.
Another thing to keep in mind when doing manual adjustments is to keep an eye on the red diode. When the laser
turns on and starts to home the red diode is large and fuzzy. As the laser head moves down the stage the red
diode becomes smaller and more focused. When the diode looks clearest you can run the focusing test to make
sure it is within range.
Laser Focus Test
Once your machine is in the appropriate height we need to run the focus test.
1. Place an anodized card above the selected material. You can use the back of your focusing card if needed.
2. Select the laser focus icon.(See Fig.25)

Manual Focus:
If one loses the QR card or simply chose not to use it, then they will have to focus the laser head
manually. The appropriate engraving distance is determined by the lenses focal length. Below is a
chart of our lenses and their required distance.
