Guys, I'm thinking of buying a 30W fiber laser, to accompany the CO2 laser that I already have. I want to have an easier and faster way to mark tools, tags, hip flasks and other, mainly, alloy stuff. I'm currently putting a list together of the wanted technical specs, needed optional (spare) parts and possible suppliers. And now I'm wondering if a rotary device for the fiber would have such an extra advantage above the one that I already use for the CO2 laser, that the extra cash is justified. What's the opinion of the ones who have both?
