Nope, it’ll stay hot on the turns.
Convert your scorpion to a raster and let it engrave, it will give you a predictable finish.
If you check this you’ll see where I did score most of the acrylic. I like the effect but my graphics weren’t as dense are yours.
Edit:
Here is your file with a raster scorpion. You’ll notice it renders a lot faster in the GFUI too.
