Hi All,
I need to do some fine engraving on acrylic so I got a lens with a shorter focal distance. The problem is that the tip of the nozzle is only a few millimeters from the acrylic and on my first attempt to engrave without air it so much junk got on the lens it almost ruined it.
So for my second attempt I tried with minimal air pressure but that caused the acrylic dust to spread and cause a haze on the piece.
Now I'm thinking why not just get a second nozzle for this kind of work and cut off the tip of it so I have proper clearance from the material? Good idea / bad idea?
Oh and my lens is held in the nozzle which is why I can't just remove it.
Thanks!
