Intentional Etching

I am wanting to etch designs on some of my projects. If I just turn down my settings it seems to do it but no matter how low I turn my setting the pierce time allows to piercing to happen. Has anyone else done this? I was looking to see if I could turn the piecing off or shorten the time but I can’t seem to find it? Does anyone have some input that may help me out?
Thanks,
Jack

Ok I found it through a google search. Much easier than I was trying to make it.
