Here is an old thread that discussed this very same subject

Cutting acrylic lots of flame underneath

I cut all thickness of acrylic on my Ruida 130W laser, but always have lots of flame under the cuts, that makes me having to hold a fan or even blow the flames out during the cutting process. Already tried air assist on, off, honeycomb, blade bed etc… just bought the ultimate assist but didnt install it yet. I already replaced the aquarium air pup for this one (https://www.harborfreight.com/1-6-hp-40-psi-oilless-airbrush-compressor-93657.html) Any suggestions to reduce this whole flame issue? …

Cheers
