The current default settings have a large discrepancy compared to the values used on-site,
leading to repeated situations where new data needs to be provided. In the case of the MAGIC fiber laser marking machine, since the primary customers aredomestic and international jewelry-related businesses, It is necessary to modify the default settings to fit jewelry applications.
White Marking [Pure Gold, Copper] (+ Surface Smooting)

Power | Frequency | Speed | Repeat Count |
40 | 25 | 1000 | 1 |
30 | 25 | 1000 | 1 |
Note: Default hatching gap is 0.02mm
Pure metals, like gold, react weakly to lasers, so a strong single pass roughens the surface, removing the gloss before performing white marking.
White Marking [Pure Gold, Sterling Silver] (+ Surface Smooting)

Power | Frequency | Speed | Repeat Count |
40 | 25 | 1000 | 1 |
20 | 25 | 1000 | 1 |
Note: Default hatching gap is 0.02mm
Precious metals react weakly to lasers, so after one pass, apply a basic power of 20 for white marking.
White Marking [Metal]

Power | Frequency | Speed | Repeat Count |
30 | 25 | 1000 | 1 |
20 | 25 | 1000 | 1 |
Note: Default hatching gap is 0.02mm
For metals with low reactivity to lasers, white marking may not be visible. Therefore, mark them with a stronger first pass, followed by a lighter marking.
White Marking [Plated Metal]
Power | Frequency | Speed | Repeat Count |
20 | 25 | 1000 | 2 |
Note: Default hatching gap is 0.02mm Power around 20–30 can be used for white marking on most metals. Two passes are better for a whiter and clearer engraving, as one pass may lack clarity.
White Marking [Thin Plated Metal]
Power | Frequency | Speed | Repeat Count |
20 | 25 | 1000 | 1 |
Note: Default hatching gap is 0.02mm
Mark lightly on plated surfaces to avoid peeling the plating (if too strong, the pink undercoat may be exposed).
Deep Engraving A [Precious Metal] - General
Power | Frequency | Speed | Repeat Count |
100 | 25 | 1000 | 10 |
Note: Default hatching gap is 0.02mm
Standard deep engraving, with speed taken into consideration.
Deep Engraving A [Precious Metal] - For Coloring
Power | Frequency | Speed | Repeat Count |
100 | 25 | 1000 | 14 |
Note: Default hatching gap is 0.02mm
Deep engraving for coloring purposes, such as on silver jewelry.
Deep Engraving A [Precious Metal] - High Quality
Power | Frequency | Speed | Repeat Count |
100 | 25 | 50 | 6 |
Note: Default hatching gap is 0.02mm Engraving deeply in one go results in slightly better internal quality. Typically used for master copies. It is not highly significant for coloring purposes.
Steel Black Marking (Hatching 0.003)
Power | Frequency | Speed | Repeat Count |
13 | 60 | 30 | 1 |
Note: Default hatching gap is 0.02 mm
A method that creates soot on the surface, leaving a slightly rough finish.
Steel Black Marking (Hatching 0.005)
Power | Frequency | Speed | Repeat Count |
12 | 300 | 10 | 1 |
Note: Default hatching gap is 0.02mm
Changes the color without leaving soot, but the process is slow.
Steel Black Marking (Hatching 0.001) +2mm Or +2.5mm Focus Shift
Power | Frequency | Speed | Repeat Count |
90 | 50 | 300 | 1 |
Note: Default hatching gap is 0.02mm
Offset the focus by +2.5mm to engrave. After confirming the position, adjust the height data only for engraving. It’s speculated that pulse values are corrected via arbitrary focus adjustment. It takes approximately 1 minute and 30 seconds to engrave an image on a 2.5cm pendant, resulting in a good black mark that appears to coat only the surface.
Active Black Marking (Hatching 0.005)
Power | Frequency | Speed | Repeat Count |
90 | 50 | 300 | 1 |
Note: Default hatching gap is 0.02mm
Brass tends to char easily, so simply increasing the power causes black soot to appear.
Metal Cutting A [Above 1mm Thickness] (Beam thickness recommended)
Power | Frequency | Speed | Repeat Count |
100 | 25 | 10 | - |
Note: Default hatching gap is 0.02mm Tapering occurs on thicker materials due to radial beam focus. Thicker beams are advantageous to reduce swelling or warping. Since cutting isn't done quickly, thermal deformation is more likely. Laser reactivity varies by metal or alloy.
Metal Cutting B
Power | Frequency | Speed | Repeat Count |
100 | 25 | 100 | 1 |
Note: Default hatching gap is 0.02 mm
Slow, deep processing is more advantageous than faster processing.
Metal Cutting C [Below 0.5mm Thickness]
Power | Frequency | Speed | Repeat Count |
100 | 25 | 1000 | - |
Note: Default hatching gap is 0.02 mm
Thin sheets warp with prolonged heat exposure.
Thermosetting Plastic ( Hatching 0.002)
Power | Frequency | Speed | Repeat Count |
20 | 25 | 1000 | 1 |
Note: Default hatching gap is 0.02 mm
For plastics, swelling and melting may occur. If power is too high, swelling worsens, and at higher frequencies, melting occurs. Faster speed is better, but the Magic Engrave machine maxes out at a speed of 1000.
Thermosetting Plastic ( Hatching 0.004)

Power | Frequency | Speed | Repeat Count |
20 | 40 | 1000 | 1 |
Note: Default hatching gap is 0.02 mm
Plastics that are highly reactive to energy require a wider hatching gap. Plastics are broadly divided into thermosetting and thermoplastic. Thermosetting plastics harden or burn under heat, allowing black soot or surface white marking, depending on the synthetic material. Thermoplastic, which melts under heat, boils, or liquefies. Thin letters engrave relatively well since the area exposed to heat is smaller, but wide areas can warp due to the heat.
Leather Marking (0.04mm) Natural Leather Only
Power | Frequency | Speed | Repeat Count |
35 | 25 | 500 | 1 |
Note: Default hatching gap is 0.02 mm
A marking method that causes surface soot, with the risk of melting on coated surfaces. Therefore, synthetic leather and rexine are difficult to engrave, but some synthetic and natural leathers are engravable. If the engraving is too strong or doesn't show up, or if a gradation effect is needed, apply the photo-marking toolpath.
Leather Marking
Power | Frequency | Speed | No. of points | Repeat Count |
35 | 25 | 500 | 10 | 1 |
Note
A marking method that produces soot on the surface may melt coated surfaces. Therefore, engraving on synthetic leather or rexine is challenging, and only certain synthetic or natural leathers are suitable for engraving.
White Marking [Plated Metal]
Power | Frequency | Speed | No. of points | Repeat Count |
10 | 25 | 1000 | 10 | 1 |
Note:
Spot marking with default settings, a range of 8–12 is appropriate, while 20 is too strong. To enhance marking quality, create a photo marking toolpath by enlarging the target engraving area by 1.1–1.5 times before generating the toolpath. By reducing the generated toolpath, a more concentrated engraving in the same area is possible, allowing for more precise details. However, if the density is too high, it may result in poorer gradation expression due to the points being too closely packed.
Black Marking [Steel, Titanium]
Power | Frequency | Speed | No. of points | Repeat Count |
13 | 300 | 10 | 800 | 1 |
Note:
Increase the for effective black marking.
