Ok, maybe I over sold it a little bit, but here it is.  It is a late and unexpected Christmas gift from my dad.  A 1000 milliwatt CNC engraving laser.  Looks like it has about a 2x2 inch working envelope max, and no z-axis.  Instead you refocus the laser for different thickness materials. 

I don't know how much practical use it will be, but I bet I am going to have a lot of fun playing with it.

That's neat!

What color?  It seems the color of the beam and the color of the material might make differences.

I didn't even consider that.  I always though the color was just a marker, and that most engraving and cutting lasers were operating in the invisible part of the infrared bandwidth.

Bob,
IR lasers are usually the ones chosen for industrial cutting, but with enough power, close enough proximity, and slow enough feed, most any color can 'engrave'.

The NEJE machine specs "Truly 1000mW blue and purple laser head, more higher speed, support more types of materials. "

Actually, the spec is 405nm, which is a "blue-violet" color.

I think the world of lasers is going to see some radical stuff over the next couple of years. Fiber lasers, where the lasing medium is the fiber itself have made huge strides. Already available from 10 watts to 100 kw at 80% efficiency! Butt welding 4" thick steel plate with 100% penetration. Shouldn't be too long before real cutting and weld lasers are common tools and priced that way.

Laser safety glasses please....   That looks like a great thing to experiment with, looking forward to reports of your experiments.

It comes with a pair for focusing on "grey paper".  Seems like the whole thing is powered by PC USB ports.  Can't be very fast.  The steppers are smaller around than my thumbnail.
