Are using sheetcam or fusion 360?
It appears that you might have your Pierce clearance not at zero.
Also you’re going to have to trim down your Pierce delay in fire control to the point where it just barely activates. .5sec and then trim it down to 75% of that in fire control.
Post your f3d file and I can look at it closer.
I did make this video on single line cutting there might be a piece and vote help you along in there.
