Nice Black On Stainless Steel with MOPA 60w Fiber Laser

Settings experimentation with a stainless steel chopper to find a nice black. In this example, the settings are consistent (shown at the end of the video) but the focus is drawn up about a half mm at a time. The Perfectly focused start produces a nice black visible from all angles, but it improves slightly by raising the galvo about a MM. Diminishing returns when raising beyond 1.5 mm or so.
