Lucky Charm

Step-By-Step Instructions

Create beautiful lucky charms out of small, simple stones!

Preparation

You Will Need:

Small, plain marble stones (we used a marble mosaic tile)

Machine Used:

Speedy 360, 100 Watt
1.5" lens
Vacuum table

You can use any laser machine from the Speedy series for this project.

Tip:

We recommend using the 1.5" lens for engraving fine details (including designs like ours).

Step by Step

Step 1: Import the Design

Create your own design, or feel free to import our template. Then, send the job to your laser machine using the following driver settings:

Print Settings

Process Mode	Resolution	Cut Line
Standard	1000 dpi	None

Halftone	Others
Colour	-

Tip:

Because of the detailed graphics, we decided to use the highest possible resolution (1000 dpi) for our engraving job. This made it possible to achieve the best possible quality.

Step 2: Engraving the Marble

First, you'll need to wash the natural dust off the stone. You can do this by holding the stone under running water. Once you've dried it, place it inside your Trotec laser machine and focus on its surface. If your stone is rounded, focus on the average value of the engraving area. Now, enter the material parameter settings. These settings can vary depending on the laser machine you are using and its available power.

Laser Parameters:

Colour	Process	Power (%)	Speed (%)	ppi/Hz
Black	Engrave CO₂	50	20	1000

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

Info:

We decided to use a negative offset value. Therefore, the surface is exposed to an increased amount of laser power, and the engraving will appear much more contrasted.

Step 3: Cleaning

Give your stone a quick wipe with a damp cloth. Be careful not to place the stone under running water this time - this might wash away the engraving dust that creates the beautiful, stark contrast you can see.
