Issue description

This issue occurs when:

• xTool materials cannot be cut through using the recommended parameters, or
• Materials that were previously cut through successfully with the same parameters can no longer be cut through.

Refer to the following for troubleshooting.

Potential causes

1. Incorrect processing parameters
2. The origin of measurement is covered
3. The slat slots are covered
4. Misaligned optical path
5. Dirty laser mirrors
6. Contaminated protective lens
7. Dirty focus lens
8. Incorrectly installed focus lens (upside down)
9. Improper focus distance
10. Laser tube power degradation

Troubleshooting procedures

1. Check processing parameters

Parameter Verification:

• xTool materials: Verify that processing parameters match the current material type.
• Non-xTool materials: Use the Material Test Array function to determine optimal parameters.
• If parameters are appropriate, proceed to the next step.

2. Check the position of the materials

The origin and the right slat slots (as shown) are the calibration points for distance measurement. Do not cover them with the materials, as this may cause defocusing.

3. Check the laser mirrors

Check each of the three laser mirrors for oxidation, dirt, or other abnormal conditions.

To uninstall or clean the laser mirrors, see the tutorial.

• If the mirrors are dirty, please follow the tutorial and clean them.
• If the mirrors are oxidized severely, please replace them with new ones.

4. Check the protective lens

Rotate the protective lens counterclockwise to remove it, then inspect for abnormalities such as oxidation or contamination.

To uninstall or clean the laser mirrors, see the tutorial.

• If the lens is contaminated, follow the tutorial to clean it.
• If the lens is oxidized or damaged, replace it in a timely manner.

5. Check the focus lens

(1) Remove the magnetic front cover.

(2) Use a Philips screwdriver to remove the screws on the focus lens holder.

(3) Take out the focus lens holder. Check whether the focus lens is damaged or dirty.

To uninstall or clean the laser mirrors, see the tutorial.

• If the lens is contaminated, follow the tutorial to clean it.
• If the lens is broken or oxidized severely, replace it in a timely manner.

6. Check the focus lens installation orientation

Critical Check: Ensure the focus lens is installed with the convex side facing up.

Method 1: Visual Inspection

1. Remove the focus lens from its holder.
2. Observe the lens shape.
3. Correct installation: Convex (curved outward) side faces up.

Method 2: Light Reflection Test

1. Place the focus lens holder vertically under the left side light panel of the machine.
2. Observe the reflected light.
3. Correct orientation: The surface that produces a narrower reflected light beam is the convex side and should face up.

7. Check the optical path

Go to ··· > Device settings > Device settings > Optical path setup > Start to calibrate the optical path. Test whether the optical path is misaligned.

Cutting abnormalities caused by misaligned optical paths often result in significant variations in cutting performance in different processing areas, with some areas even failing to emit light. You may also attempt cutting tests in different areas. If you need to calibrate the optical path, see the tutorial.

• If the optical path is misaligned, please refer to the guide and software prompts to complete the calibration.
• If the optical path is aligned, exit the settings and check for other issues.

8. Check the model of the focus lens (if any)

Check the focus lens model matches the lens holder (xTool P3 comes standard with M-type focus lens).

If you have multiple focus lenses, you can distinguish their models by the markings on the packaging. If packaging markings are unavailable, observe the lens's convexity—the shorter the focal length, the more convex it is, that is, the height of the bulge: S>M>L.

9. Laser tube power degradation

For most CO₂ laser engraving and cutting systems, laser tube power degradation can occur under two main conditions:

10. Check the airflow of the air pump

Go to the link to check and troubleshoot the airflow issues during cutting.

11. Check the beam combiner mirror

Go to the link and check whether the beam combiner mirror works properly.

• If the mirror is clean, reinstall it and recalibrate the optical path.
• If there is some dust or dirt on the surface, clean the beam combiner mirror following this tutorial.
• If the mirror is oxidized severely or cracked, get a new beam combiner mirror for replacement.
