These are the best settings for engraving black color over aluminum with a MOPA fiber laser engraving machine BCF or JPT.
1200 or 1000
45% or 30%
250 or 540
Pulse: 10 or 6
HATCH : 1
HATCH type: Bidirectional
LINE SPACE: 0.003 or 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 MOPA, these parameters can engrave black with a 10x10cm lens. The result is smooth and does not take coat out.
These parameters have been tried with a fiber laser BCF 30W MOPA with a 10x10cm Opex lens.
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.
