Laser Settings adjustments


I am new at all this including laser. I have been trying to determine how to adjust the settings in Vcarve so that I can more fine tune the darkness (or lightness) of the projects outcome. I have tried adjusting the power, the move speed In the toolpath section (I have Vcarve laser module) and even tried to adjust the max burn rate in the tool database. The outcomes are not consistent. Any tips on how i can adjust so i can depend on the results?

Also have attached two pictures. One of run on letters (was suppose to say -SPEED) and the other where I am trying to do a fill but the machine also puts an outline in the result.

Any input would be helpful.
Thanks
Peter

For consistency I use 100% power, move speed 40mmps, hatch fill, step over .1mm, fill regionally, cross hatch checked. This is with VCarvePro 11. Be sure your laser focus is right on. Refocus if necessary.

I also found that under fill regionally a 45 degree angle is fastest.
