Laser settings
22.1 Set laser parameters
Specify laser parameters that apply to all objects in the marking file, such as laser power and
scan speed.
If you set a high laser power or a slow scan speed, the workpiece may catch fire or burn
depending on the material.
For test marking, it is recommended to set a lower laser power value and a rather fast scan
speed. Check the marking quality and adjust the parameters gradually until the marking
result meets your expectations.
You can specify values for laser power, scan speed, pulse cycle (LP-RF, LP-RV) or pulse
duration (LP-RV). The values will be transferred to the “Test marking/guide laser” dialog.
• Go to the “Marking settings” screen and select “Laser settings”.
Specify any of the following parameters:
• “Laser power”:
Set the power level according to your actual requirements.
The laser power gradually decreases due to the degradation of the laser source. Due to
that fact, it is recommended to set a value below the preset value of 100.
• “Scan speed [mm/s]”:
Specify the speed at which the laser beam moves while marking the workpiece.
• “Laser frequency [kHz]” (LP-GS, LP-RC):
For LP-RC, the laser frequency is predefined to 40kHz and cannot be changed. For LP-
GS, you can adjust the laser frequency.
Changing the frequency results in different marking effects. For example, a lower
frequency and a higher scan speed will generate a dotted line. It means that the laser is
not generated quickly enough to mark a continuous line.
• “Pulse duration [ns]” (LP-RV):
Specify the laser pulse duration.
By entering a value, the value for the pulse cycle is automatically adjusted to the optimal
value. If required, you can specify another value than the optimal value.
A shorter pulse duration reduces the thermal effect on the workpiece. Adjust the pulse
duration according to your desired marking quality and the material of the workpiece. The
following values are reference settings for different materials:
‒ Plastic: 4ns or 8ns
‒ Metal: 16ns or 30ns
‒ For shallow marking on metal: 120ns or 200ns
