These are the best settings for engraving black color over copper with a fiber laser engraving machine BCF, Raycus, JPT or others.
HATCH : 1
HATCH type: Bidirectional
LINE SPACE: 0.001
Note: These engraving parameters are for reference, and the results may change deepening on the lens, power laser source brand, metal mixture, ETC.
In our BCF 30W, these parameters can engrave black with a 10x10cm lens. The result is a roasted black colour, is not a black smooth colour as in the SS. But you may try it on your own and check if it is a valuable result for you.
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.
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.
