i have a 600mmx400mm chinese laser cutter, with a lid
I cant keep all the smell going out, I have both a 273 cu feet a minute squirrel/furnace style fan and the fan that came with it which is similar style just a little smaller, and both of them running together and it still doesnt seem to be enough, which I absolutely cant have.
I have tried opening the top which visibly makes it look like all the smoke is rushing out,
keeping it half open,
putting tape around the seems of most of the doors,
taping the vents that are factory cut into the door and removing a long thin rectangular panel right below the top cover/door to try and draw air from a little below the table and keep smoke from being right by the vents in the door/top.
both fans have their own 4" duct that I mounted to a board in a window in that room and then closed the window against it and taped around the edge.
any tips, I have seen people online with a laser cutter in their office room in a house, and surely they are getting all of the smoke/smell out?
