Inner engraving cannot be performed in glass materials.

Possible causes

• The actual dimensions of the glass are inconsistent with the dimensions set in the software.
• The glass material you are using is not compatible with inner engraving.
• There is an issue with the Z-axis focal length.

Troubleshooting

Step 1

Check whether the type of the glass you use is suitable for inner engraving. Not all types of glass are suitable for inner engraving; for instance, tempered glass, laminated glass, and deeply tinted glass may not be engravable. It is recommended to use our official materials for inner engraving.

Step 2

Ensure that the actual dimensions of the glass are consistent with the dimensions set in the software.

Step 3

Ensure that the processing mode you select is Inner Engraving.

Step 4

If there are still no marks, you can perform Inner Engraving Z-Axis Calibration to ensure the Z-axis focal length is accurate, and then try engraving again.
