This page describes a laser cutting setting published for Feutrine / laine at 1 mm, tested on a LaserPecker 1 Pro fitted with a Diode 0.5W source (445 nm blue diode, 0 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 Feutrine / laine at 1 mm does not transfer to another thickness, nor to another source. A 445 nm blue diode rated 0 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 Feutrine / laine, 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.
LaserPecker focuses on very compact, sometimes portable machines with diode or infrared sources, driven from a phone. The nomadic format means small work areas and precise mechanical focusing: a few millimetres of offset changes the result faster than on a gantry.
Felt cuts with a sharpness scissors cannot match, and the edge is heat-sealed so it does not fray. Provided you can tell real wool from synthetic felt.
Wool felt cuts cleanly, with a burnt-hair smell and a slightly browned edge. Synthetic felt (polyester, acrylic) melts: the edge turns hard, sometimes glassy, and yellows.
Neither contains chlorine, so both are laser-safe — but avoid unlabelled blends, and above all anything with a plasticised backing.
Very little energy and high speed: felt cuts almost instantly. The right setting is the one that goes through without browning more than a tenth of a millimetre either side of the line.
Felt lifts in the air-assist draught. A honeycomb bed, magnets or a cardboard frame stop an already-cut piece shifting and being cut twice.
Engraving felt is rarely worthwhile: the laser crushes the fibres rather than creating contrast. Keep it for cuts and fretwork.
