Marble lucky charm

Step by step instruction

Quickly turn small marble stones into lucky charms for any event.

Preparation

Required material:

small marble stones (we used a marble mosaic tile and removed them from the mat)

Machine used:

Speedy 360, 100 Watt
1.5" lens
Vacuum table

For this sample you can use any laser machine from the Speedy laser engraver series.

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

Make your own design or import our template. Send the job to the laser using the driver settings below.

Print settings

Process mode	Resolution	Cut line
Standard	1000 dpi	none

Halftone	Others
Color	-

Tip:

Due to the detailed graphics we used the highest possible resolution of 1000 dpi for our engraving job.

Step 2: Engraving the marble

First, wash the natural dust off the stone under running water. Once it is dry, position it into your Trotec laser and focus on the surface. If the stone is rounded, focus on the average value of the engraving area. Enter the material parameter settings. The 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 used a negative offset value. Thereby the surface is exposed to more laser power and the engraving shows more contrast.

Step 3: Cleaning

Wipe off the stone with a damp cloth. Don't put it under running water, because this might wash out the engraving dust which ensures the good contrast.
