Sculpfun S30 Pro Max settings for Slate coasters
To engrave Slate coasters on the Sculpfun S30 Pro Max (20W module), start at 45% power, 3000 mm/min, 200 LPI, 1 pass. These are manufacturer and community starting points; run a test grid before a real job.
Starting points, not gospel. Rows marked “starting point” come from manufacturer tables and community results. Run a small power/speed test grid on your own sheet before a real job — batch, humidity and focus all shift the result.
| Module | Job | Thickness | Power | Speed | Passes | LPI | Air | Status |
|---|---|---|---|---|---|---|---|---|
| 20W | Engrave | — | 45% | 3000 mm/min | 1 | 200 | — | Starting point |
How to use this chart
- Focus first. Set focus on the material surface with the brand's focus tool or the fixed-focus spacer. A 0.5 mm error halves cutting ability.
- Run a test grid. A 5×5 grid of power (20–100%) against speed (cut: 100–1000 mm/min; engrave: 1000–6000 mm/min) on your actual sheet takes ten minutes and saves a ruined blank.
- Add passes before power. If a cut doesn't release, add a pass. Extra power at low speed just chars edges.
- Air assist on for cuts. It clears smoke from the kerf and keeps the lens clean; it is usually off or low for engraving to avoid blowing dust into fine detail.
Frequently asked questions
Why does my Slate coasters cut not go through at these settings?
Focus is the usual culprit: set the focus at the material surface (or 1/3 into thick stock), check the lens for smoke film, and confirm the belt tension. Then add one pass before adding power.
Should I change speed or power first?
For engraving, change speed and keep power moderate — it protects the diode and reduces charring. For cutting, run at 100% and tune speed and passes.
Do these settings transfer to another machine?
Only roughly. The Sculpfun S30 Pro Max module power (20W) and spot size drive the numbers. Use our page for your exact machine.
