We are considering getting a 5" lens in the near future and was wondering, since fiber is less forgiving then co2 when it comes to focus, how much more depth of focus would you gain on stainless steel for example?
With the flexx lens at the moment I can go out of focus by roughly 2mm until it starts annealing.
We do lots of personal items and such, most are reasonably flat like zippo lighters, etc. But then there are those curved items that can be a bit more awkward to engrave.
I've searched the forums and the only posts I've found are about galvo's, which doesn't really help a lot since galvo's have a completely different delivery method for the laser beam. There are also those few occasional jobs where the extra clearance would come in handy as well.
