    Amazing work VDX! How long did it take to assemble it? I was thinking about getting a similar machinery one day.

    ... the "pure assembling" is done within some hours with all parts there -- but the development/redevelopment/reiteration/rework tooks some weeks ... this sort of building/developing of fancy machines is the "hobby" of my boss

    ... tested to cut 0,3mm thick brass sheets - it's much easier to cut and finer result than Aluminium!

    ... found some "historical" bits - the Resopal-plate was from my first image-milling tests around 1987, when I've got my first Isel-CNC-mill running with a self programmen driver+CAD/CAM software on Atari-ST and vectorized some pixel images within the paint program STAD, to engrave logos and images.

    The time difference between the milled images and the laser-engraved Aztek-kodex is nearly exact 30 years -- and pretty good showing the then and now "current state of technology"

    I've looked at the picture in post #16 several times over the past two days, Victor, and am more and more impressed each time I see it. The accuracy is simply amazing.

    Hi David,

    the original of the "Aztek Kodex" is a stone fresco with some 3 meters in diameter with many fine details, so a pretty complex geometry, when shrinked to the sizes I've done here.

    The bigger "goldish" one is 80mm big, the smallest white from Resopal has 40mm and the steel one in post #16 has 60mm diameter.

    I'm testing different materials and parameters, so creating some complex and "representative" objects for the next exhibitions is a bargain

    Viktor, how much would you say you have invested in this project - including the cost of the 85 watt cw fiberlaser?

    Also, just to clarify: the .2 mm steel plate that you etched was done using the same CW laser, correct? (Not a pulsed laser?)

    I must agree with David - the detail on that round steel piece is nothing short of astounding. I've seen work come off a Trotech laser that cost upwards of 80 grand that didn't look that good. You guys are really onto something here...
