Monport 40W CO2 is mechanically similar to K40-class and OMTech 40W machines; apply the same baseline: 200 mm/s, 20% power, 0.08 mm line interval in LightBurn. Machine top speed is ~350 mm/s. Air assist built-in. Source: monportlaser.com/blogs/40w-lightburn-ready-co2-laser-engraver + cncsourced.com/guides/laser-engraving-anodized-aluminum-etching

Good stamp relief. Invert design. 500 DPI for fine text.

Excellent contrast on bamboo. Clean sharp lines.

Bright white engrave on slate. Invert image. CO2 gives great results on stone.

Good leather engrave. Start at 20% and increase if mark is too light.

Clean cut. Remove film. Vent well.

One pass through 3mm MDF. Keep air assist on to manage fumes.

Good engrave quality. Monport machines are well-built for the price.

Similar to OMTech 40W. Tube quality varies — test your specific tube. Air assist on.

CO2 cuts leather beautifully with sealed edges. Slightly charred edge is normal on veg tan — wipe with damp cloth.

What can a CO₂ laser like the Monport 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 40W CO2 more versatile for craft and production use.
