Upgrading the Air Assist is one thing I highly recommend for your Co2 Laser.
This Ultimate Air Assist Kit installed in your laser can improve your engraving and cutting results. It will also enable you to control the Air via the Software for each cut/engraving layer.

If using the standard air pump and exhaust fan, these can be connected to the outlets controlled by the relay installed in diagram below.
If using an Air Compressor, it is best to have this running off of a separate mains outlet not controlled by the air assist relay. And the Exhaust fan can use the air assist relay outlet as shown in the diagram below.
This following diagram shows an example of the wiring configuration of the relay for the rear power outlets.
This video demonstrates how to install this on the Chinese Red & Black Laser, it is the same process for most laser machines using RuiDa controllers. This can also be installed on Trocen Controllers, so check out my other Blog post for information relating specifically to Trocen Controller Air Assist Installation.
