Quick FAQs

Are these Glowforge Pro settings guaranteed for Natural Slate?

No. Treat them as recommended starting points. Run a small test cut or engrave before you use a full sheet or finished part.

Why does 45W matter?

Wattage affects how much energy can be delivered at a given speed. A lower wattage machine may need slower speed or more passes than a higher wattage machine.

Should I change air assist for Natural Slate?

Follow the row when air assist is listed, then adjust during testing. Air assist can reduce flare-ups and improve cut edges, but some engraving jobs may need less airflow.
