So I've read through multiple threads on how people vent, and my current setup should be more than enough to not have fuming in my garage. Granted I have the HF 2HP dust collector, but it's rated at a high enough CFM that it should have no issues pulling fumes. Whether its acrylic or wood, we're getting heavy fume smells coming into the garage. I checked for leaks, and made a few adjustments which helped a little, but we're still getting fumes. When the extractor is running, you can see it drawing smoke, but it isn't as impressive as I think it should be.

Is it possible for fumes to be escaping the dust collector motor? Any other suggestions on what to check? I cleaned the extraction ports on the laser so I know that isn't an issue. I'm scratching my head.

Oh and for understanding, we vent directly outside.
