Turning fan off or down for thin material?

[nemesis]

I am trying to cut very thin rubber, but the fan that turns on while the laser is running is blowing the material around. Is there any way to change the setting of the fan?

Alternatively, is there something I can buy to put on the rubber first to keep it from moving? Like how the proof grade material has a covering on it that peels off?

No control for the air assist at this time. A lot of folks use magnets to hold the object down. Also, these things are really awesome:

the best laser results are achieved with flat (non warping materials) in order to maintain consistent focus. Also, when cutting light materials like paper, the exhaust turbulence can kick up the material and ruin your job or at worst… catch fire. (speaking of which, I hope you all keep a small fire extinguisher in easy reach, near your machine - safety FIRST) I hope you find these useful. I used to 3d print them for my other laser cutter but occasionally , they would see the wrath of the laser …

Stick it onto a stiff surface. My brother @timjedwards taught me to use MDF with a light coat of spray adhesive, for cutting paper. Seems that would work just as well here.

Get yourself some of this:

Then spray a couple coats on a draftboard, stick your paper to it and cut.
