I thought i had posted these settings in the past but couldn’t find them, so here they are:
speed 300
power 25
1 pass
Use set focus. If you can’t for some reason, use material height 0.07

Just curious, how much curling do you get? I cut some 10 mil mylar and it no longer lays flat. It’s not potato chip bad, but it just lifts in places and makes it difficult to get a clear register.

When I did 10 mil previously, I laid it on a piece of copy paper. Speed 300, Power 25. I didn’t have any curling, but perhaps the material varies.

Thanks! I have a stack of 7 mil that I’ve been wanting to cut into stencils. Does it fly around?

I got my stencil material from @smcgathyfay about five years ago. She is a professional airbrush artist and used the material to make airbrush stencils. The particular material she sent me had a treatment that made it better for laser cutting but I don’t remember in what way. It does not curl and it cuts very cleanly without pilled up edges. Unfortunately she hasn’t been seen on the forum for years, so I don’t know what I’ll do when I run out of it.

I stick it down to the crumb tray with very tiny neodymium magnets, with a piece of card stock behind it to improve visibility and reduce flashback. I rarely see flying bits with the 7 mil, and never with the 10 mil.

Thanks for posting this! I have a bunch to cut. Might need to use 10 mil though, want them to last for tracing.
