I'm really at a loss of how to set up an appropriate exhaust system. Theres a light smell of the acrylic and wood when cutting/engraving inside my 10x10 workspace. Right now its being vented outside. But when I removed the wood off the grid today there was white smoke trapped underneath so obviously it's not exhausting correctly. I'm not sure if it's the piping, the blower, or what. I need help
