DAHAN L6 (L2) machine installation - laser light path adjusting

This video teaches you how to debug the laser optical path.
However, because the machine has been debugged before leaving the factory, users do not need to do complete debugging after receiving the machine. Or you don’t need to spend too much time on debugging.
Just check the light path and make fine adjustments.
In addition, after you are familiar with the light path dimming method, you can adjust the light path well in a few minutes.
