Hi,

I live in Australia and recently bought a 100w laser and I'm mostly loving it.
I bought it from China, so the instructions were pretty much non-existent, but I'm a tech at heart so I've figured out most of it.

I've got it in my garage, but I live in a suburb, so I need to figure out a proper venting / extraction / filter system.

I've also had the volume fill up with smoke a few times during failed exhaust setups, so I think I need to get onto the lens and clean it up.
I've seen that cotton buds with acetone is a way to go..?

Cheers.
