Hi Adam,
the last parts were made with a 20 Watt pulsed fiber-laser, not with the 85W-CW-laser.
The results in steel are comparable with the CW- and pulsed lasers -- with other, more shiny/reflective materials the pulsed laser will be much more effective!
The CW-lasers were "random" parts, I've got in exchange of some of my old gears and private developments, so it's mostly counted/paid in time and ideas, not money.
The pulsed fiber-laser and galvoscanner in the showed setup was sourced and built in my day-job, so a totally different game -- this is my money-making job ... but I'll get it for my private use, when the next "updated" version will be functional
We plan to sell the complete marking system with software, equipped with this pulsed 20W laser, for around 15 thousand Euros ...
