You need a better blower. What you're smelling is A) acrylic (it stinks when cut) and B) left over fumes. What type of blower are you using? Needs to be at least 600 cpm A cheap option is the 2 hp harbor freight blower. (called: 2 hp dust collector, just throw away the bags) You might even be able to get away with the 1 HP if your exhaust run is short.
