Manual Focus
Retrieve your April tag card first. Ensure that the side of the card labeled "Focus Card V1.2"
is facing upward. Position the card under the camera.
Note: If your machine does not
move when the autofocus
button is hit, then lower the
gantry and try again.
Lens Focal Length Distance from Material
163mm 203mm
254mm 294mm
330mm 370mm
420mm 460mm
Note that the numbers in the chart refer to the distance from the lens to the object, not from
the lens to the workspace. If you switch to a larger object, adjust the stage accordingly.
During manual adjustments, keep an eye on the red diode. When the laser turns on, the red
diode will appear large and fuzzy. As the laser head moves down the stage, the red diode will
become smaller and more focused. Stop adjustment when the diode appears clearest, run
the focusing test to ensure that it falls within the desired range.
Focus Test
Once you’re machine is in position, locate and select the Focus Test Icon.
The Focus Test window will open, ensure that you have selected the appropriate lens size
then select the "Generate Test Pattern" button to produce a grid.
The focal length of the lens determines the amount of distance between it and the
material. Refer to the chart below for the required distance for each of our lenses.
From the grid, choose the two markings that appear most
similar to one another. Enter these markings into the pattern
selection and save the results. For example, in this image we
selected 3F and 4D as they appear to be most similar.
