this is how i have the laser and computer setup ,with the exhaust through the wall ,i also have manual control of the compressor and exhaust fan as when i am programming or designing i don't want that equipment running ,especially in the winter pumping out my heat.
But the exhaust is important as cutting some materials produce smoke that is probably not good to breathe.
I keep my machine greased and clean on the inside and outside.
I keep a piece of glass on the inside to show me how much residue collects then i know when the lens/mirrors need cleaning (sort of a tell tale)
I clean the mirrors and lens frequently as i cut wood and there is a lot of smoke.
I also have a manual damper on the wall where the exhaust goes through and keep it shut when the machine is not in use again to conserve my heat.
