Monport GP 40W CO2
The Monport GP 40W CO2 is a 40W co2 laser engraver and works with LightBurn. This page lists 17 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 materials can the Monport GP 40W CO2 engrave or cut?
The Monport GP 40W CO2 has community-tested settings for Stainless Steel, Cork Sheet 3mm, Marble Tile, Cotton Fabric, Foam Board 5mm, Bamboo 3mm, Chipboard 2mm, Corrugated Cardboard, and 9 more. Results vary by material batch, focus, and ambient conditions — always test on scrap first.
Is the Monport GP 40W CO2 compatible with LightBurn?
Yes, the Monport GP 40W CO2 works natively with LightBurn.
What settings should I use to cut Cork Sheet 3mm on the Monport GP 40W CO2?
A community-tested starting point is speed 28 mm/s, power 35% in a single pass. Enable air assist for a cleaner edge. Always run a test cut on scrap to confirm before committing to your project.
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.
"Used it with a Glowforge — engraved beautifully with no changes. I will be purchasing more digital downloads from this shop."
