hello, I have a laser master 2 15w with until few days ago worked very good.
today after few hours of engraving I noticed that there are two blue dot showing (see the pictures I attach). what could be the cause of this? how can I solve it? in the engraving process this seems not to be a problem, the engraves come out sharp and well done.
another problem is that I can see some movements when I engrave letters, (look at the H and the E in the picture.).
I tried thightening the bolts and the situation got a little better, but still not perfect.
at what torque can I tighten the bolts?
the belts seems well positioned and tensioned to me.
With the lens removed. Put on some safety glasses fire the laser against a flat black item and see if it has 2beams. Not sure if a ortur LM2 15w is a dual led unit or not. Also make sure to turn the power down when doing that.
It could be that at 25% (or another percentage) only 1 led is being used and at 80+% both led’s are used. To be honest I don’t know if the led’s need to be in an exact alignment (or very close) before the lens is screwed on.
Maybe you can contact Ortur directly for a comment on this.
