This page describes a laser engraving setting published for Carton ondulé at 2 mm, tested on a Wainlux K8 fitted with a Diode 10W source (445 nm blue diode, 10 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 engraving setting that works on Carton ondulé at 2 mm does not transfer to another thickness, nor to another source. A 445 nm blue diode rated 10 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 445 nm blue diode, and never leave the machine unattended.
Wainlux targets the very compact and portable, with small enclosed diode engravers driven from a phone. The small work area and low power point towards object marking rather than cutting.
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.
