Hi, some questions, if you can shed some light:

-what goggles you use for adjusting and looking at whats going on? i have been looking at Eagle Pair® 190-540nm OD4+, what exactly would i need to see when adjusting and working with the laser?

-Is this driver ok? I am considering it, cause its here in Europe

-How to adjust the driver to 2.4A so it would not burn the diode, cause it can output up to 3A. i searched for this, but as am really not into electronics


- i am looking at the Nichia NDB7875, very roughly maybe equivalent to your 2 diodes. is it better to buy a double driver and in the future fix 2 of them and achieve ~5-6W. I mean is there any real benefit, for engraving in general and gray scale engraving?
