Re: [CAD_CAM_EDM_DRO] sawdust

The best method is a round hood with a strip brush around the
circumference. This also doubles as a guard to protect you from flying
bits when something goes crunch. The commercial CNC machines usually
spring load the hood so it presses firmly on the surface but if you use
fairly long bristles on the brush you can get away without this.

Add a decent dust extractor to the hood and you will catch most of the dust.

For a 2HP router the hood needs to be at least 12" diameter to allow the
sawdust time to decelerate a bit before it hits the brush. If the hood
is too small you will have a rooster tail of sawdust flying out past the
brush.
