NO compound/product, etc., will ever dust if you keep it just moist enough to work through its process from the initial cut to breaking down and finishing the work..
I use a Makita 9227C all day and never get dusting, because I don't allow it to happen...
Perhaps pay better attention to what the surface looks like while you are working on it and when it starts to change color and looks drier, then you spray it with something to get it back..
In the olden days of acrylic lacquers and enamels, it was just going to be a dusty compounding, and then if you really wanted it dusty again, you used cornstarch as the last step to clear up the paint more...
And I always said to myself, I hate all this dust !!!

Now I have to get the airchuck and blow it all off, it then gets all over the floor, and then get it all out of all the jambs, again, and again...
You need great lighting, so you can see what is happening, you have to absolutely watch the work and not get distracted, and you need to mind how you started off that part of the panel -
Did you prime the pad?
Did you moisten the pad with something like C/G Pad Conditioner?
What speed are you using, and how much pressure are you using ?
Im of the opinion that you create your own dusting - if you want it - and you can also not create dusting - if you want it...
