Fiber Laser Marking Machine’s Red dot is running, but no marking?
Red dot is running, but no marking?
Operation problem:
First, check if the material can absorb the 1064nm laser wavelength.
Second, if on the correct focus distance marking? What’s the output laser power? If it is bigger lens? Usually the laser will be weaker for bigger lens, also the depth of focus is relatively shallow, prone to this situation.
Third, check the marking content, if it is JPG or BMP format picture.
How to check on this situation? Use a piece of stainless steel, type TEXT, HATCH line distance is 0.05, laser power is 80%, speed is 500, chose Continue, then marking, up and down the marking head, will find where the problem from.
Parameter setting problem
Check the laser control model, if chose YAG model.

Laser source problem
If all the above 2 checked well, then will be laser source problem.
Fist, cut off the whole machine for 5 minutes, then reboot, if still can not mark, then need to check the laser source. Put the white dimming paper below the marking head, if can see the green laser spot. If can not, then laser source problem, further troubleshooting is required to resolve the problem either by laser failure or laser power failure
