These are the best settings for engraving over white on aluminum with a fiber laser engraving machine BCF, Raycus, JPT or others.
HATCH : 1
HATCH type: Unidirectional
ANGLE: 90 or 0
LINE SPACE: 0.03
Note: These engraving parameters are for reference, and the results may change deepening on the lens, power laser source brand, metal mixture, ETC.
Highly reflective materials shouldn't be engraved directly under the lens and should be set up outside the center of the engraving area.
These parameters have been tried with a fiber laser BCF 30W with a 10x10cm Opex lens. Also, These parameters can be applied to Raycus and JPT, but the BCF has a broader range of Frequency, which gives a better amplitude of effects.
We have used EZcad 2. But these parameters also apply to EZcad 3 and, in general, any laser control card from JCZ.
Speed, frequency, hatch, and line space, can remain the same, but you may change the power percent if you own a laser with more power or less power.
All this information does not represent the engraving time. The time varies depending on the design or pattern to engrave.
