The Monport GP 40W CO2 is a 40W co2 laser engraver and works with LightBurn. This page lists 59 community-tested settings covering speed, power, passes, air assist, and DPI across a range of materials. Always run a test cut on scrap material first — results vary depending on your material batch, focus, and ambient conditions.
The Monport GP 40W CO₂ is a galvo-head CO₂ laser, meaning it uses fast galvo mirrors for raster engraving rather than a gantry. This makes it dramatically faster for engraving large flat areas compared to a standard gantry CO₂. Galvo CO₂ machines are popular for high-volume photo engraving on wood, leather, and slate. The trade-off is limited cutting ability and a smaller marking field. Best for engraving-heavy workflows.

What can a CO₂ laser like the Monport GP 40W CO2 cut that a diode laser cannot?
CO₂ lasers can cut and engrave clear acrylic, glass (with care), fabric, and thicker wood more cleanly than diode lasers, because the CO₂ wavelength is absorbed by materials that are transparent to diode light. This makes the Monport GP 40W CO2 more versatile for craft and production use.
