"Red dot is running, but no marking"-Fiber Laser Marking Machine
During using fiber laser marking machine,we may encounder following problem-Fiber laser marking machine Red dot is running,but no marking.
Here are we list three steps,help you find the solution.
1.Operation problem:
First, check if the material can absorb the 1064nm laser wavelength.
Second, pls kindly check fiber laser marking machine,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 marking head, then we will find where the problem from.
2.Parameter setting problem:
Check the laser control model.
It is in Fiber Laser model or not,if not,change into Fiber Laser model.
The laser control of fiber:
3.Laser source problem:
If above info are well, let us check fiber laser source or laser power supply.
Fist, cut off the whole machine for 5 minutes, then reboot.if still can not mark, then need to check the laser source.
uninstall F-theta lens,adjust parameter as follows:
Put the white dimming piece below the marking head,pls kindly check if you can see the green laser spot on dimming piece. If can not, then laser source problem, further trouble shooting is required to resolve the problem either by laser failure or laser power failure
