VCarve problem

so I have downloaded the PP that has been posted on here for VCarve and it is working great, but no mater how I set my z1 and z2 the z axis never plunges or rises it just starts cutting the project from the z zero amount and drags threw the work. I have tried what I could to my knowledge. Thinking it’s in the PP which I suck at.

Can you share some example gcode? I don’t know about vcarve, but I’d be curious to see the gcode.
