Honest review! Looking for a starter laser, but think I”ll go for a fully enclosed one…

I am totally new to lasers. Longer told me the spot size for the 12W was .01mm. I bought this machine for 2 purposes only....1) is to create color designs in steel and 2) burn off paint to make watch dials...that is where the .01mm spot size is needed. Your video mentioned a realistic spot size of .06mm. Do you think I could achieve a .01mm spot size for just removing paint?

[@ThisDesignedThat]

0.01mm (10 microns) is no way achievable with these types of lasers, but for etching in paint for watches do you really need 10 micron precision? I would guess 0.1mm is more than enough for legible results on a watch dial. This laser is not suitable for colour engraving on steel, for that you would want a fiber laser not a diode laser. Preferably a MOPA fiber laser.

I wonder why they told me spot size was .01mm.? They have shown color markings on steel and other users have replicated the colorings on steel so I know that’s possible.

@@chrome72 listed specs are 1 thing, real specs are another, its definitely got a fine dot size, and small enough for any intricate work. Colour marking is possible but you get a much wider colour gamut with a mopa fiber. For the price that nano pro is hard to beat, especially with the accessories that you get with the packages.
