Place the picture frame on the bed of your Trotec laser machine. Because this is a bulky object, make sure the areas to be engraved are flat for the engraving, as you will be engraving both the wooden frame and glass in one pass (note you will also need to position a distance holder due to the leg on the back of the frame). Focus on the glass.
Because we're engraving materials with height differences you must calculate the z-Offset. In our case we put an offset value of +7 mm as the height difference between the two materials is 7 mm. Please note the parameters can vary depending the machine you are using and available laser power.
|Laser Parameters ||Color ||Process ||Power (%) ||Speed (%) ||ppi/Hz |

|Light engraving (wood) ||Red ||Engrave CO2 ||10 ||50 ||500 |
|Engraving (glass) ||Blue ||Engrave CO2 ||40 ||50 ||500 |

You can use leftovers of acrylic or MDF for the distance holders. Cut them in circles or cross-shapes.
