Not sure if this has been mentioned yet. If you want to turn off the chamber exhaust fan or run it at a slower speed for certain parts or filaments you can follow the steps in my pictures.
- Go to the printer settings and enable “Air Filtration Enhancement” for the H2D
- Open up the filament settings for the specific filament you want to adjust it for.
- Enable “Activate air filtration”
- Adjust the speed of the fan as desired. 0% = off.
