Important Operation Reminder
The calibration operation of the UV laser module + UV Internal Engraving F-theta Lens (purple) involves certain professional requirements and uncontrollable operational risks. It is not recommended to perform it by yourself unless necessary. Please proceed with caution!
If your device is a complete unit pre-installed with a UV laser module from the factory:
After completing the module replacement and F-theta Lens replacement restart operations, if the software does not pop up a calibration prompt, it indicates that the equipment parameters are normal, and no additional F-theta Lens calibration is required.
If you have certain professional knowledge, and wish to self-check the status of your equipment (prioritize self-inspection instead of direct calibration):
In the Falcon Design Space software, you can engrave any pattern within the 70mm format, verify that the parameters of the 130 field lens and the violet light module operate normally, and then determine whether calibration is required.
Carefully check the status of the equipment calibration board:
If this error occurs, troubleshoot and fix it step by step in the following order, and none of the steps can be omitted:
Contact official customer support and upgrade the device firmware via OTA to version 1.2.6 or later, then attempt calibration after the firmware update is completed.
Reconfirm that the calibration plate is firmly installed with precise position, and there are no problems such as offset, looseness or skew.

Should either of the above two situations arise, this tutorial provides two solutions:
Option 1: (You will need a printer, A4 paper, and scissors.)
please use the calibration sheet file provided officially, print it on plain white A4 paper with the actual size printing setting (ensure the cross lines are dark and clear). Then attach the printed calibration sheet flatly to the original calibration board, making sure there are no wrinkles or curled edges, and retry calibration after it is firmly attached.

Option 2: (Alternative option if you do not have a printer)
Please prepare the following items:

Please ensure the 5W UV laser module and the UV flat-engraving f-theta lens are installed before proceeding.

1. Confirm that the device is connected and the 5W UV module is installed.
2. Confirm that the engraving mode is "Plane Engraving"
3. Confirm that the layer parameters are correct
4. Put in white paper (size must be larger than 130mm*130mm, non-reflective) and heavy objects (coins in the reference picture). The heavy objects must avoid the cutting line, and then click "Auto Focus"

5. Click "Frame" to ensure the engraving area does not extend beyond the edges of the material.
6. Click "Go Processing" to complete the engraving; the result will look like the image shown:

7. Adjust the layer toggles as shown in the image (disable the top two layers and enable the third layer).
8. Put in white paper (size must be larger than 130mm*130mm, non-reflective) and heavy objects (coins in the reference picture). The heavy objects must avoid the cutting line, and then click "Auto Focus"
9. Click "Frame" to ensure the engraving area does not extend beyond the edges of the material.
10. Click "Go Processing" to complete the engraving; the result will look like the image shown:

11. Simply attach the two materials onto the calibration board.
After completing all the troubleshooting and repair operations above, restart the calibration process, follow the on-screen prompts of the device step by step strictly, and do not skip any steps or operate arbitrarily.
First perform factory reset on the device
After recovery is complete, use the Falcon Design Space software to engrave a pattern within a format of 70mm to self-check the operating status of the equipment
If the self-check shows abnormalities and the problem remains unresolved, please contact us
