How can i spot pierce?

I think Burgs explains it real well here…

Creating a center point to have a pilot hole

For me, the best way to get a “pilot” hole is as follows. In fusion, I make the pilot holes I want cut a diameter of 1/4" or .250". I create a tool path for those holes with tool only for those holes. The tool has a kerf of .249". When creating the path I set it to no lead in, no lead out and no pierce clearance. When the machine cuts the hole it is effectively a hole with .001 diameter plus the actual diameter of your plasma, so something between .050" and .065". The kerf size of the tool …

See if that works for you and let us know how it goes!!
