Marble lucky charm

Step by step instructions

Use our step-by-step tutorial and template below to laser engrave lucky charms out of small marble stones.

Preparation

Required material:

Small marble stones (we used a marble mosaic tile and removed the stones from the mat).

Machine used:

Speedy 360, 100 Watt
1.5" lens
Vacuum table

You can use any laser machine from the Speedy laser engraver series to create these clever trinkets.

Tip:

Use the 1.5" lens if you want to engrave fine details as shown in our graphic

Step by Step

Step 1: Import design

You can import our template for your design, or you can create your own. When your design is ready, send the job to the laser engraver using the driver settings below.

Print settings

Process mode	Resolution	Cut line
Standard	1000 dpi	none

Halftone	Others
Color	-

Tip:

If you are engraving detailed graphics, we recommend using the highest possible resolution. We used a resolution of 1000 dpi for our laser engraving job.

Step 2: Engraving the marble

Start by rinsing the stone under running water to remove any dust. Then place the stone it into your laser engraver and focus on the surface. If the stone is rounded, focus on the average value of the engraving area. Determine and enter the laser engraver parameters. The material parameters can vary depending on laser machine and available laser power.

Laser parameters engraving:

Color	Process	Power (%)	Speed (%)	ppi/Hz
black	Engrave CO₂	50	20	1000

Passes	Air Assist	Z-Offset	Advanced
1	on	- 0.5 mm	-

Info:

We wanted to achieve a bold contrast with our design, so we used a negative offset value. This exposes the surface to more laser power so that the engraving shows more contrast.

Step 3: Cleaning

When you are finished processing, wipe off the stone with a damp cloth. Placing the processed stone under running water could wash out the engraving dust, giving your engraving a lower contrast.

Inspiration

Add value to your laser engraved stones by engraving sayings, slogans or quotes on the stones. You can also make a gift more personal and meaningful by personalizing the stones with names or dates.
