- Rotary attachment

- Sponge or a spray and some water
Trotec laser used
- Speedy 300,
- 80 watts,
- 2.0 inch lens
Use a 2 inch lens instead of a 1.5 inch lens to prevent the glass from cracking
Step 1: Mount the rotary attachment
Before you start working, ensure the laser machine is switched off. Once this is done, you can then mount the rotary attachment and plug it in. After that, switch on the laser and place the prepared glass into the rotary attachment.
Step 2: Prepare the glass
In order to prepare the glass, you will need a paper towel, some water and a spray or sponge. Apply a paper towel on the surface of the glass and moisten it with a sponge or spray. This will prevent splintering of the glass. To help achieve a perfect result, ensure that there are no air inclusions or wrinkles.
Step 3: Put the glass into the rotary attachment
Insert your prepared glass into the rotary attachment and make sure that it is firmly attached. If your glass is conical, adjust the inclination angle so that the surface you wish to engrave is in a parallel position.
Step 4: Engrave your glass
Import the PDF file into Corel Draw. Feel free to customise the existing design as you wish or create your own unique design and send it to the laser. Ensure that you have activated the rotary attachment and entered the diameter of the glass in the properties dialogue (see screenshot in step 3).
