So I should have a separate venting system for etching than I do for carving? I’m curious - are there any X-Carve users with lasers that do that?
I have never seen a single fleck of anything - hot or cold - come off my laser. Again, I have the small 2.8 watt unit that I use to engrave. I guess if I was trying to CUT items like paper I might be a little concerned but I’m not even sure about that. I do use poster-board to proof engravings. I do it a lot. But still, I have not seen anything hot coming off during the process.
Yes, something could go wrong and the laser could start a fire that could be sucked into the dust system but the same can happen with the router. But an explosion? Everything I have read makes it fairly clear that the concentration of sawdust in the normal home workshop environment is never high enough to explode. It is my understanding it would have to be dense enough you can’t see across the room. And when running the laser there is no new dust introduced.
Just my 2 cents…
My laser is mounted to the right using one of J-Tech’s mounts (see J-Tech’s photo below) which allows the typical shoe vac hose to remain in place. With my homemade shoe, I simply remove the bottom brush plate and insert a blank plate (no bristles) that holds the hose in the same position. It handles the smoke/odor just fine.
