Having trouble using the center punch operation

I’m still new at this I asked a couple of questions and got some good answers from the form I’m getting pretty good at making stuff going through five 4 x 10 sheets of 12 gauge steel covered all Christmas presents for everybody but the question I have today is I’m trying to put center punches in and I set it up it makes the first punch perfect and then blow through the rest of themThen it stops like it supposed to I hit start again and it cuts the perimeter out perfectly.
