Have you done a lot of work with the laser?
Dust and soot can build up on the lens and block the laser and reduce it’s result.
You can try canned air and see if that helps.
Also some people have used a q-tip with isopropyl alcohol.
I personally would try to stick with things meant for cleaning optics for cameras and telescopes: lens cleaning paper & brushes & fluid.
I have cleaned my laser but without success.
I do not know if the laser is defective and for some reason does not emit power.
The machine works, you can see the blue dot, but the paper remains white. Do I need to contact support?
thanks for the help
When I open the housing doors, the laser turns off, so I assume that works with the doors.
The doors are open or closed, make contact or not. I guess only a bit does not work. I also have the door lock on and off both on on LUBAN and directly on the SM.
I couldn’t get my laser to calibrate properly either, but after some experimentation, I was able to calibrate it manually.
It might be different for every laser, but maybe try the following:
disable auto calibration
disable auto focus
set the laser height to 26mm (if that doesn’t work for you, try experimenting with the height).
Did the trick for me.
Also, triple check your cable connections.
