I am considering a small focused fan to blow debris into the exh fan mouth.
What are you using. They make very powerful high speed hand blowers now- perhaps something like that rigged to a power source?
I have the old air pump that came off my OMTech laser. I have a flexible tube that I put air directly on the part… noisy and a pita but works. Also takes up real estate.
I’ve also done a cheap variation of the fan blowing across it, but it doesn’t work as well as blowing down into the object. It does help with ventilation as far as I can tell.
I’m kind of, of the opinion for my fiber laser, that pulsed air would work better, unlike my other lasers.
Hi Jack. I think that old air pump is probably a pulsed air pump- most are.
Yea, to some extent, never opened it up… don’t know if it’s a vibrating diaphragm or not.. probably is. Since I had one laying around, I thought I’d try it.. On deeper engravings it seems to work better.
