30W vs 20W Fiber Laser Marking

I marked a grid with my 20w fiber laser in a previous video. I'm now marking the same grid (same settings / same ezcad file) with a friend's 30w fiber laser to see the difference. This 30w laser has a much larger marking area and longer focal length so it's not an apples to apples comparison. I suspect the 30w would be significantly darker at the same settings if it had the same 150x150mm marking area as my 20w laser.
