I have a Ruida 644 controller and I am curious to know if the dust blower air pump (which is plugged into the back of the laser enclosure) can be turned on and of via Light burn rather than being powered on all the time. Not sure if there is a relay controlled by the board or not.

I believe it’s possible by running a solid state relay off the ‘Status’ output, and plugging the blower in through that. When the controller is running a job, the status pin is set (or grounded - this is the part I’m not sure of).
The Wind Pin grounds.
I completed one of my Lasers this week for On - Off - Automatic (set by layer).
I did a post in December on my solution. It also has a time delay when the job is finished to clear out any remaining smoke.
