I'm reading/hearing different information on the air assist use and psi when it is on.
I have been running air assist on, with a 60w boss laser. Seems to blow a little bit of debris when rastering, but masking solves that issue when it arises.
What is a major issue, is cutting 1/4" birch plywood in complex shapes/curves I'm having all kinds of problems with flair ups. Literally can't get through even slightly complex words even soaking the wood with water without it just burning through letters.
I've read on here in numerous threads that air assist actually helps "blow out" flair ups. I'm seeing the opposite effect though. At least that is how it appears to the naked eye. It looks like when the laser passes back over spots that have been cut nearby (like a close cursive L) it starts to burn and the air just fans the flame before I can stop the damage.
I tried cutting once tonight with air assist off and it worked perfectly, BUT I just read all about how that can have negative affects inside the cone and even crack the lens.
So what's the answer? What do I try next? Been using the Chinese air pump (best guess is about 30 psi coming out), but have the air compressor plumbed in now so I can start playing with different air settings via a direct regulator.
Could I just need a little less air? Or WAY more?
