Screw the support pillars onto the base plate. Install the positioning rulers on the X and Y axes of the positioning panel respectively and tighten the screws. Then insert the positioning panel onto the support pillars.
Adjust the positioning rulers according to the actual size of the material to ensure the material is centered.Example: For a 50×50×50mm crystal, set the positioning rulers to 25mm.
Secure the fully assembled internal engraving stand at the center of the engraver’s working area.Do NOT lift only the working panel when moving the stand, to avoid component damage or positioning deviation.
Open the FDS software, connect the device, and confirm it is Creality Falcon T1.Go to 【Workspace】 and select 【5W UV】 as the light source.


Click 【Processing Mode】

Select 【UV Internal Engraving】 mode.

Click the 【Material】 tab.

Measure and enter the actual dimensions of the material.

The software includes built‑in professional internal engraving parameters. Hover the mouse to view parameter descriptions.Modification is not recommended except for testing purposes.

Import the 3D model.

Select the model, then adjust its position, size, and rotation angle as needed.

Tip: Finer texture on the top surface. For best results, place the main view facing upward during processing.

After adjustment, click 【Generate Point Cloud】.

Once the point cloud is generated, the model cannot be moved. To re‑adjust, click 【Restore Point Cloud】.

Perform auto‑focus directly on the assembled internal engraving stand.Do NOT place the crystal material at this stage. Correct focusing ensures an accurate border preview.

Click 【Border Traversal】 to preview the actual engraving area on the internal engraving panel.Confirm the processing area before proceeding.


After previewing, place the crystal material tightly against the positioning rulers to keep it centered. Ensure the material is stable and not offset.

Click 【Start Processing】 to preview the full engraving path.After confirming no abnormalities, close the engraver protective cover, then click the start button to begin UV internal engraving.Do NOT open the protective cover during processing.
