So last year I bought a cameo 3 used off a friend for $100. This is basically the same as a cricut that your mom or wife possibly owns. I'm currently running a cb09 blade from amazon with the 30 degree blade. I then purchased this $10 pen holder and put a fabric pen in it.

I have my cb09 blade set to force 28, speed 5, passes 3. Blade depth has to be set manually, and I have the blade pretty far out there.

I have my pen set to force 18, speed 10, passes 1.

This is all for 500d nylon. As you might expect, there is not a ton of information out there for using these craft machines for cutting tactical nylon. Hopefully finds this helpful down the road.
