Place the photo frame on your laser machine's work table. Be sure that the areas you want to engrave are laid flat, since both the wooden frame and the glass will be engraved together in a single pass. Be aware that you will also need a distance holder because of the frame's back leg. Focus the laser on the glass.
Since we are engraving two materials with different heights, we need to calculate the z-Offset. For this project, since the difference between our two materials' heights is 7 mm, we set the z-Offset to +7 mm. Please keep in mind that depending on your laser machine and the specific photo frame that you are using, these settings can change.
|Laser Parameters ||Color ||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 could use any leftover scraps of acrylic or MDF if you have them. Cut them into circles or cross shapes for easier use.
