The picture is older and in black and white but I cant seem to make the engraving darker regardless of power settings.

Here is a recent example of an engraving I did. Is speed the best way to regulate the final darkness of a gray scale engraving? Will 100ipm be darker than 150ipm with the same min/max power settings on a gray scale engraving?

If not is there a general rule of thumb for making this decision? I know there are provided thumbnails when selecting an engraving method, but I’m not quite sure I understand the benefits to either one.If the above is true, should I just leave my min/max power settings at 0/100 during any gray scale operation?.When using gray scale does my min/max power setting actually effect the outcome of the engraving or does the software adjust itself accordingly based on the picture provided?.I am using a Jtech 7W laser attached to a Shapeoko XXL. They typically come out much lighter than expected. Specifically I continue to have issues regulating the darkness of the engraving. I am hoping to get some help understanding a few aspects of the gray scale engraving process.
