To autofocus your machine, you need to retrieve your April tag card first. Ensure that the side
of the card which says "Focus Card V1.2" is facing up, and position it under the camera.
There are two methods to autofocus your machine.
1. The first method involves navigating to the touch screen and selecting the Autofocus
icon located on the Home page.
2. The second method requires you to go to the Jog Controls, select the Autofocus Icon,
and enter RE3.
Note: If your machine does not
move when the autofocus
button is hit, then lower the
gantry and try again.
Note that the numbers in the chart refer to the distance from the lens to the object and 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 and
begins to home, the red diode will appear large and fuzzy. As the laser head moves down the
stage, the red diode becomes smaller and more focused. Once the diode appears clearest,
you can run the focusing test to ensure that it falls within the desired range.
After you have focused your machine, locate the Focus Test Icon and click on it.
This will bring up a focus test window. Ensure that you have selected the appropriate lens
size and click on the "Generate Test Pattern" button to produce a grid.
The focal length of the lens determines the distance between your laser head 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 instance, you may choose
3F and 4D as they appear to be similar.

Focusing:
Dual Diode:
A diode is affixed to the rear of the machine and positioned according to the focal length of the
lens. The laser can be focused by lowering the Z-stage until the machine diode aligns with it.
When switching lenses, the rear diode will need to be readjusted to accommodate the new
focal length. This can be achieved by autofocusing your machine and then adjusting the
position of the back diode until it aligns with the laser. Once the adjustment is made,
perform a focus test to ensure optimal results.
1. Remove any objects or work pieces from underneath the lens work area. Ensure laser
head is in a reachable position to remove lens.
3. Place the lens cap onto your lens to protect the lens from potential damage.
4. Carefully twist counter-clockwise to loosen the lens.
Try not to damage the camera or camera shutter located on the side of the scanhead.
Avoid touching the glass surface of the lens to prevent scratches. The lens collar may come
loose with the lens,if that occurs remove both together and separate once dismounted.
5. Replace the collar to the scanhead before inserting a new lens.

Lens Calibration:
Lens Size(mm) Working Area Approx. (mm)
163 110X110
210 140X140
254 175X175
330 220X220
420 300X300
Access the "Laser Tools" page by navigating to the Machine name, locating
Diagnostics, and selecting Galvo Calibration. Alternatively, you can type the IP
Address/setup in your web browser to access the same page.
Preparation:
To perform a lens calibration, ensure that the QR card is positioned within the camera's
view, with the Calibration April Tag facing upwards. The card should be placed outside
the work area and parallel to it for accurate calibration. The size of the work area is
determined by the lens in use (refer to the chart below).
1. Once the Laser Tools page is loaded, locate the Laser Focus and Lens Calibration section.
Ensure that the correct lens size is saved in the lens section. If the wrong lens setting is
saved, then all subsequent calibrations will need to be redone.
2. Select Run Lens Calibration.
The red diode will disappear, and the camera will slowly turn off. The diode will start scanning
the work area. After the calibration is finished, you will be given a pass or fail result.
If your test fails, it could be due to lighting in your work area. If it is too bright, close any open
blinds or turn off lights before retrying. If it is too dark, try placing a white piece of paper under
the laser diode to improve visibility.
After the machine passes the calibration test, we recommend performing a camera capture to
ensure the QR card was positioned correctly. If the QR card was not placed parallel to the
work area, the camera may be calibrated improperly.
An example of a wrongly calibrated camera is when the workspace is shifted by the angle of
the QR card. If this happens, you should re-run the calibration.
Once the machine is successfully calibrated to the lens, we need to perform mark and
preview adjustments to ensure the laser properly engraves in its new work area.

Mark Adjustment: Preview Adjustment:
Parameter Test:
To verify the success of the lens calibration process, run the mark adjustment. Ensure
that the speed and power settings remain unchanged, but adjust the size parameter.
The size refers to the dimensions of the square that will be marked, and its value
depends on the lens size being used.
1. Place a flat piece of test material under the laser for marking.
2. Preview the square before proceeding to ensure that only the test material will be
marked.
3. Select "Mark Square".
Measure the marked square. It should match the size chosen earlier. If the lens
calibration was not done correctly, the marked square may be off by approximately
2mm. In that case, re-run the lens calibration and redo the lens adjustment.
Please note that the intentional cut-off of the top left corner of the square.
4. Select "Save Mark Adjustment".
After confirming that the mark adjustment is accurate, proceed to mark a new square by selecting
the "Mark Square" button.
1. Without moving the previously engraved material, press the "Preview Square" button.
2. Make use of the adjustment buttons to align the tracing made by the red dot precisely with the
marked square.
3. Finally, select "Save Preview Adjustment" to save the adjustments made.
If your not sure what types of settings you want to use for your materials, then try using the Laser
Parameter Test. It can be found directly under the Laser Tools tab on the Setup page. The
Parameters Test will generate a graph to test the two parameters chosen at their minimum and
maximum values, with the spaces in between determined by the grid size. This means that a
larger grid size makes it easier to narrow down your selection.
The parameters you can test are: Power, Speed, Frequency, DPI, and Pulse Width. Pulse Width
is a parameter only used in MOPA machines. To access the Setup page, go to the Machine name,
then go to Diagnostics and select Galvo Calibration. Next, select the Parameters tab.

Focus Tag Calibration:
Ensure that your machine is properly focused before starting the calibration process. Take note of the Z-stage
coordinates displayed on the Main Unit screen to ensure accurate calibration.
Navigate to the Laser Tools page and locate the Galvo Autofocus Calibration section. Select the Autofocus Mode.
AprilTag:
Choose the AprilTag option to calibrate the Focus card. Place the Focus tag in the center of the work space.
Click on the Take Snapshot button to capture an image with the camera. The Focus Tag should appear on the
screen with a red box above it. If the box does not appear, it may indicate a damaged Tag.
Ensure that the tag size is saved as 19.44.
Set the lower offset for your stage. It is recommended to start with a value of 120 and adjust from there.
Saving the focus will cause the machine to move to the lower offset position. If the lower offset is set too low, it
may hit zero and return to the previous location. Set the lower offset as close to the bottom as possible for optimal
accuracy.
After saving the focus, move the stage from its position and test the autofocus. If done correctly, the stage will
return to its previous focus location.
Note: The mode that is not selected will be inaccessible.
Red Diode:
To adjust the red diode, select the TwoDots option.
Position the back diode to the desired location.
Select Update Ref. Position.

Q: What should I do if my laser isn't marking?
A: Check if the laser is properly focused. If the machine is not at the right height, it won't
engrave. Refocus the laser head after changing to a new material. Still having difficulties, make
sure that your material is compatible with your laser engraver.
Q: Why are my marks turning out incorrect?
A: Experiment with different settings to find the ones that work best for your requirements. Here
are some initial guidelines to get started:
● To get darker/lighter engravings, adjust the power or speed.
● To get deeper engravings, decrease the speed or increase passes.
● For clearer engravings, use a picture with a high resolution.
Q: What should I do if my engravings are too shallow?
A: You may need to increase the power and/or decrease the speed. Multiple passes can also
add more depth. You can also use a smaller lens to engrave in more detail. For precise
engravings, ensure that the laser is fully focused by performing a laser focus test every time
you switch to a new material.
Q: How can I solve issues with focusing my laser?
A: If using auto-focusing with the QR tag, ensure that the QR tag is visible in the camera during
the entire process. If the tag goes off-screen, the machine won't focus. If it doesn't work, try
manual focusing.
Q: What should I do if my engravings look wobbly and uneven?
A: If you've recently calibrated your camera, check that you did it on a flat, smooth, and level
surface. Otherwise, recalibrate on a different surface. Another reason could be that your
material is not flat while engraving, it can come out uneven. Flatten and/or weigh down your
material before engraving to avoid this issue.
