Glass cracks when it gets too hot, so the goal is to put less heat into a larger area. Use the settings and tips below as a starting point, then test on a spare piece.
Starting settings
| Setting | Starting point |
|---|---|
| Power | 20–35%, as low as possible |
| Speed | 300–400 mm/s |
| LPI | 200–250, as spaced out as possible |
| Focus | Defocus by 1–2 mm |
Defocus to spread the heat
We recommend defocusing, especially with a powerful tube. Lowering the bed about 2 mm spreads the beam over a larger area, which makes the spot slightly bigger and the heat less concentrated. A 4 inch lens also gives a naturally larger spot.
Choose the right glass
Glass behaves differently depending on how much lead it contains. More lead means the glass heats up faster and holds heat longer. That is why crystal is not ideal for lasering. Inexpensive glass with a low lead content, like the kind sold at a dollar store, gives the best results.
More ways to shed heat
- Lay a wet piece of newspaper over the glass.
- Apply dish soap to the glass.
- Use a 4 inch lens.
