Hey all,
I have spent my morning playing with our fiber laser (Trotec fiber 30w) trying to achieve a colored etch on stainless steel. I think we have all seen many examples of this over the years...

http://www.spilasers.com/applications/redenergy/colour_marking_with_a_fiber_laser.aspx
I have tried dozens of combinations of power/speed/frequency/focus and am no closer to figuring it out. I have also searched these forums and haven't been able to find much info for the settings. I have heard that its a difficult and inconsistent etch that relies on heat more than anything else.
Can anyone tell me more about this process? I know settings dont transfer from machine to machine as well as we would like but I would be open to hearing about the broad strokes of the method. Should I be using a high-wave length or low? Multiple runs? High power? Any info would be appreciated.
Thanks!
