This page describes a laser cutting setting published for Carton ondulé at 3 mm, tested on a Vevor VV-40W CO2 fitted with a CO2 40W source (10,600 nm CO2, 40 W). It states the exact machine, source, material, thickness and operation of the test; power, speed and number of passes are shown with a Premium pass.
Why those four facts matter: a cutting setting that works on Carton ondulé at 3 mm does not transfer to another thickness, nor to another source. A 10,600 nm CO2 rated 40 W does not deposit the same energy as a stronger module, and the speed has to be adjusted accordingly. Copying a number without checking those four points is the first cause of a ruined part.
Published by LaserSettings (estimation). No other workshop has confirmed it yet: treat it as a starting point, and confirm it from your account if you reproduce it.
No photo comes with this setting yet. If you reproduce it, publish yours from your account: a picture of the result is worth more than a line of numbers.
Recommended routine before running the part: clean the lens, redo the focus, engrave a small test grid on an offcut of the same Carton ondulé, then adjust the speed rather than the power. Work with fume extraction and air assist, wear glasses rated for 10,600 nm CO2, and never leave the machine unattended.
Vevor distributes entry-level CO2 and fibre machines under its own name, often without detailed source documentation. This is the typical case where measuring with your own test grid beats trusting the advertised power.
Corrugated cardboard is the prototyping material: free, available everywhere, it lets you validate a cut before committing plywood. It is also the most fire-prone.
Corrugated board is not a solid material: the beam crosses two liners and a void. The cut is therefore uneven if speed is too high — the void lets the beam diverge and the bottom liner stays attached in places.
One pass at moderate power and medium speed works better than two fast passes, which re-cut the same line and widen the burn.
For a jig prototype, double-wall board behaves almost like 5 mm solid: an excellent test of your paths, not of your settings.
This is the material that catches fire fastest, and the flame travels inside the flute where you cannot see it. The rule is absolute: never unattended, extinguisher within reach, and inspect the piece before closing the machine.
Printed or laminated board (food packaging, glossy boxes) contains unknown inks and films: prefer plain brown board.
The edge stays brown and dusty, which does not matter for a prototype. For a visible final piece, solid grey board (bookbinding board) gives a much cleaner edge.
