I'm using the HF 2hp on our 2x4 CNC, mostly cutting Walnut and other hardwoods but occasionally MDF for templates or fixtures. It seems to work good with my homemade dust shoe though, as others have said, it doesn't pick up large chips but gets the dust out easily - smaller chips get sucked right up just like the dust. It's rare for me to run another tool while the CNC is running so it gets the full capacity of the DC all to itself.
