Hmm…would a tarp or something to cover the enclosure altogether be good enough? Or would you guys recommend something else for when in use?
Just for some perspective on this, from here: https://www.laserpointersafety.com/
As long as we’re talking diffuse reflections from wood or some non-shiny object then incidental exposure to the beam is generally not regarded as hazardous.
I personally try to wear my goggles whenever the laser is on, however I know that if I were to accidentally catch a stray reflection from wood through a gap in the enclosure for a fraction of a second it’s going to be fine.
The main hazard is children or pets who would be likely to stare at the dot.
The diffuse reflections are unlikely to burn through or cause fire to any material like a tarp or other opaque covering, so that would probably be fine for use on wood.
Specular reflections from shiny materials like tile, jar lids, glass are extremely dangerous and can cause near instant retinal damage as you will be getting nearly the full power of the laser. The nominal ocular hazard distance of a 10W laser is in the ballpark of half a mile (2320 feet) before it’s spread enough to not cause eye injury from a specular reflection.
I would encourage everyone to be extremely cautious around the laser as it has significant potential for injury. The best place for operation would be in a room that can be closed off when in use, or in an opaque enclosure or one employing rated laser viewing windows without gaps.

A cheaper enclosure can be used, I use a grow tent it is total blackout so safe with the Laser.
It keeps my machine clean as well as its set up in the garage, I have led lights inside off my 12V solar system and these reflect of the silver sides of the enclosure and give a very even light. I use octoprint to control and watch the prints or Laser with the attached camera, this is the safest way to watch it.

Agreed…as long as it doesn’t trap smoke. That will stain your surface even faster.
You could also just make the existing enclosure opaque, just put some paper over the panels. If you want to get fancy, you could make some curtains for your enclosure.
To prevent smoke going to the lens and to improve lasering there is “air assisted lasering”. I read it is very important a good design of the air system to force the air in the correct path to prevent lens to get dirty.
The new head does have a new airflow design. How effective it will be is anybody’s guess.

The new head’s airflow is very effective, it actually blows smoke out the side of cardboard (e.g. turning the corrugation into vents) as I’m cutting cardboard.
Just to clarify. The enclosure is not required to use the 10W laser. I recently received mine and can confirm it does not require it. BTW, it is awesome. The auto focus makes it MUCH easier. Cuts are cleaner and less burn on top, likely because it moves faster. Results are great.
That said. It is a more serious tool. Needs the respect. Use the included eye protection. Also, make sure you have good ventilation.
