Place the photo frame onto your laser engraving machine's bed making sure that the areas to be engraved are flat. This is because we want to engrave both the wooden frame and glass in a single pass (note you will also need to position a distance holder due to the leg on the back of the frame). Focus your laser on the glass.
As we engrave materials with height differences you must calculate the z-Offset. In our example we put an offset value of +7 mm as the height difference between the two materials is 7 mm. Please note the parameters vary depending on the laser engraving machine used and its available laser power.
|Laser Parameters ||Colour ||Process ||Power (%) ||Speed (%) ||ppi/Hz |
|Dark engraving (wood) ||Black ||Engrave CO2 ||35 ||50 ||500 |
|Light engraving (wood) ||Red ||Engrave CO2 ||10 ||50 ||500 |
|Engraving (glass) ||Blue ||Engrave CO2 ||40 ||50 ||500 |
|Laser Parameters ||Passes ||Air Assist ||Z-Offset ||Advanced |
|Dark engraving (wood) ||1 ||On ||+7 mm ||High Quality |
|Light engraving (wood) ||1 ||On ||+7 mm ||High Quality |
|Engraving (glass) ||1 ||On ||- ||- |
For the distance holders you can use leftover material such as acrylic or MDF. Circles or cross-shapes work better.
