Dust Collection

It is possible to plumb multiple tools into one system using 4-inch PVC or sewer pipe and blast gates to direct suction specifically to the CNC when needed. 

However, because CNC machines produce fine dust continuously for long periods, we advise that a dedicated high-pressure extractor or a multi-stage cyclone is often more effective.

Noise level is a critical factor for long CNC runs, as a standard shop vacuum can be significantly louder than the machine itself and may become a nuisance over several hours. 

To mitigate this, hobbyists recommend choosing extractors with lower decibel ratings (like the Nilfisk or Fein) or placing the vacuum in a ventilated, sound-insulated enclosure or a separate room.

Yes, you can automate your dust extractor by using the M8 (coolant flood) G-code command, which triggers the VAC power port on the Onefinity controller.

A proper cnc dust collection system should prioritize high static pressure to pull chips through long, narrow hoses and include a cyclone separator to prevent fine dust from clogging filters and burning out motors. 

Onefinity officially recommends and uses the Fein Turbo I internally due to its reliability and built-in power bypass, though many hobbyists also favor Festool extractors or the Nilfisk Attix 30/50 for their quieter, brushless motor options.
