Air assist is similar to coolant on a lathe – we use it to keep the cut/engraving area free from debris and the beam path clean from smoke.
Smoke assist is a term coined by k40.se in 2014 to describe the help of air flow inside the machine to keep the optics free from smoke and keep the dirt from settling on your optics.
