This tutorial applies to the adaptation and calibration of the 5W UV Laser Module (ultraviolet) and the UV Internal Engraving F-theta Lens (purple)
¶ 1. Preparatory Work
Please prepare the following items and materials in advance before calibration begins

The device is powered on, and the 5W UV laser module (ultraviolet) and the UV Internal Engraving F-theta Lens (purple) have been correctly installed.
If there is a mismatch or the laser module needs to be replaced, please first check the tutorial for replacing the laser module: https://youtu.be/-ZZXBVmFkyU
Ensure that the device firmware has been upgraded to the latest version (V1.1.29 or higher)
Please turn off the air purifier during the calibration process to avoid strong wind interfering with the position shift of the calibration card.
- The carving process will generate a certain amount of dust and fumes, please wear an N95 mask.
¶ 2. Important Safety Instructions
UV Internal Engraving F-theta Lens (purple) is only suitable for UV laser module (ultraviolet), and it is strictly prohibited to mix it with the IR & Diode laser Universal F-theta Lens (black)! Using a mismatched F-theta Lens will cause damage to the F-theta Lens.
During the calibration process, the laser is invisible ultraviolet light. Please be sure to wear protective glasses.
Do not start calibration with the cover open to avoid burns.
¶ 3. Instructions for Calibration Sequence
Laser Module Calibration → Auto Focus Calibration (Recommended, Skippable) → F-theta Lens Calibration
Please use the interactive screen for calibration.

- During the calibration process, if a fault code pop-up window appears, you can refer to this guide
¶ 5. Start calibration
¶ Step 1: Laser Module Calibration
(1) Click the "Settings" tab
(2) Click the "Calibration" tab
(3) Click "Start Calibration"
(4) Confirm to turn off the safety protection, then click "Next"
(5) Double-check and click "Next"
(6) Install the Calibration Stand , ensuring that the stand is firmly fixed and correctly positioned.

(7) Close the protective cover
(8) Click "Next"
(9) Waiting for device preparation
(10) Wait for the preview frame to appear, then open the protective cover
(11) Place the flat new anodized aluminum oxide (Laser Module Calibration Card) on the stand, ensuring that the preview frame appears completely within the card and the corresponding edges are parallel and aligned.
- The card must be brand new, flat, and free of warping, and the preview frame must not exceed the card; otherwise, the calibration results may be inaccurate.
(12) Close the protective shield
(13) Click "Next"
(14) Waiting for device calibration
- Do not open the protective cover or shake the device during the process, otherwise the calibration results may be inaccurate.
(15) Calibration completed, click "OK", open the protective cover, and remove the anodized aluminum oxide (Laser Module Calibration Card)
- Calibration completed indicates successful calibration (no error pop-up)
- The exhaust fan will delay shutting down, and when the pop-up window appears, the task has already ended
¶ Step 2: Auto Focus Calibration (Recommended, Skippable)
(1) Click the "Settings" tab
(2) Click the "Calibration" tab
(3) Click "Start Calibration"
(4) Empty the device baseplate and ensure it is clean and free of debris
- Includes removing the Calibration Stand / Internal Engraved Stand (if any)
(5) Close the protective cover
(6) Click "Next"
(7) Waiting for device calibration
- During this process, do not open the protective cover, nor place any auxiliary materials. Just wait patiently (usually a few dozen seconds).
(8) Calibration completed, click "OK"
- Calibration completed indicates successful calibration (no error pop-up)
(9) Return to the "Workbench" to verify the calibration effect
(10) Click "Auto Focus" and wait for auto focus to complete
(11) Click "Manually Adjust Z Axis"
(12) Observe whether the value of "current reference machining height" is less than or equal to 0.5mm. During subsequent machining, the equipment will automatically focus according to the material thickness to complete the adaptation of the focal length.
- 0mm to 0.5mm is the normal fluctuation value
- If it is greater than this value, please perform "Auto Focus Calibration" again
- If the issue persists, please contact after-sales customer service
¶ Step 3: F-theta Lens Calibration
(1) Click the "Settings" tab
(2) Click the "Calibration" tab
(3) Click "Start Calibration"
(4) Install the Calibration Stand , ensuring that the support is firmly fixed and correctly positioned.

(5) Place the flat new laser engraving photo paper (F-Theta Lens Calibration Card) on the bracket
(6) Close the protective cover
(7) Click "Next"
(8) Waiting for device calibration
- Do not open the protective cover or shake the device during the process, otherwise the calibration results may be inaccurate.
(9) Open the protective cover and take out the laser engraving photo paper (F-Theta Lens Calibration Card)
(10) Close the protective cover
(11) Click "Next"
(12) Waiting for device calibration
- Do not open the protective cover or shake the device during the process, otherwise the calibration results may be inaccurate.
(13) Open the protective cover
(14) Place the laser engraving photo paper (F-Theta Lens Calibration Card) unengraved back side on the empty stand
(15) Close the protective cover
(16) Click "Next"
(17) Waiting for device calibration
- Do not open the protective cover or shake the device during the process, otherwise the calibration results may be inaccurate.
(18) Calibration completed. Click "OK", open the protective cover, and remove the laser engraving photo paper (F-Theta Lens Calibration Card)
- Calibration completed indicates successful calibration (no error pop-up)
- The exhaust fan will delay shutting down, and when the pop-up window appears, the task has already ended
¶ 6. Calibration completed
Now your UV Laser Module + UV Internal Engraving F-theta Lens (purple) has completed all calibrations and can be safely and accurately put into production use.
- After calibration is completed, "Stop on cover open" will automatically restart. However, to ensure safety, it is recommended to check whether "Stop on cover open" is enabled to avoid injury caused by light leakage.
- (1) Click the "Settings" tab
- (2) Click the "System" tab
- (3) Check if the "Stop on cover open" switch is on. If it is off, please turn it on.
