Quick FAQs
Are these Glowforge Pro settings guaranteed for Clear Acrylic?
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 Clear Acrylic?
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.
