This page describes a laser engraving setting published for Céramique émaillée at 6 mm, tested on a DIY / Machine maison Diode GRBL 32 bits + infrarouge fitted with a Infrarouge 2W (1064nm) source (1064 nm infrared, 2 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 Céramique émaillée at 6 mm does not transfer to another thickness, nor to another source. A 1064 nm infrared rated 2 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 Céramique émaillée, then adjust the speed rather than the power. Work with fume extraction and air assist, wear glasses rated for 1064 nm infrared, and never leave the machine unattended.
The DIY / Machine maison machines listed here are tied to the source actually fitted to them: that source, not the model name, decides which settings apply. Before reusing this page, check your source's power and validate the values on an offcut of the same material.
On glazed ceramic the laser does not engrave the clay: it acts on the glaze. The mark is crisp and permanent, ideal for tiles, mugs and decorative tableware.
The result depends almost entirely on the glaze, not on your settings. A dark glaze gives a very visible light mark; a pale glaze may give nothing at all. A test tile from the same batch is the only way to know.
With CO2, work at high power and fast speed, single pass: the aim is to micro-fracture the glaze, not to carve it. A fibre source marks some glazes far more finely.
On a mug the surface is curved: without a rotary, keep the design about 30 mm wide to stay within the focal range.
Ceramic can crack under thermal stress, especially a thin or already-cracked piece. Wear glasses and do not lean over the part.
A mark on glaze is not certified food-safe: avoid areas that touch lips or food, and do not count on heavy dishwasher cycles.
A gentle soapy brushing removes micro-flakes and makes the mark crisper to the eye and to the touch.
