Fiber Laser Research: What 3D engraving is better - classical or inverted?

Trying to get better results from 3D engravings made on my Fiber Laser.
Any considerations of support would be greatly appreciated!

Hi, which parameters have you used? is it a 50 Watt Machine? I'm using 50 Watt Raycus for cutting and engraving Gold/Silver.

I have 50W JPT. I do two passes - one to engrave, but it leaves a lot of slag that will absorb laser energy on subsequent passes, so I alternate engraving and cleaning passes. Engraving/cutting of thermal reactive metals would be much harder. I haven't worked on cutting yet.

@@UtterlyMad Interesting approch to engrave and to clean the passes!
