So, my thinking is, that while the gun may "feel" softer in the setup many recommend (with the lower dwell), it is actually harder on paint.
Why not run the setup suggested, but instead increase dwell?
Feel free to set me straight, if the Axe is different, and decreasing the dwell actually makes it softer on paint (which frankly would surprise me, and I'd like to understand why).
Don't think anybody ever answered this question yet.
First off, changing dwell will have varied effects based on the type of marker in question. There isn't a universal rule of thumb that applies to every marker, at least not in my experience.
In stacked tube poppets, where FSDO and stickage isn't as much of a concern, lowering dwell will definitely make the gun smoother. However if your marker isn't broken in then you should leave it at the stock setting until you've put more paint through it or you may get poor consistency due to less consistent valve lift. Remember, as you decrease the force on the moving parts friction becomes more of a concern. If you have to raise your pressure to compensate for lowering your dwell, you should probably leave it stock.
In poppets raising dwell tends to make them kick more because the ram/ bolt assembly are moving faster and the poppet valve will be opened longer, allowing more air though and causing slightly more pneumatic recoil. It can also increase consistency, due to more consistent valve lift.
Unbalanced spools react to dwell adjustments vaguely similar to poppets, but you'll have to worry more about fsdo.
In balanced spools raising dwell simply raises the amount force used to cycle the bolt and doesn't affect the amount of air being released like poppets and unbalanced spools. higher bolt speeds will be rougher on paint.
That being said, the best dwell in balanced spools is the lowest setting that will allow you to consistently overcome static friction, as this will exert less force on the bolt and therefore the paint. This value will also change from one marker to the next depending on how broken in they are and the temperature they are being used in. Obviously colder temps necessitate higher dwells.
The axe/mini use a very different operating system with a different solenoid, so they react differently. In my experience, assuming the same operating pressure is used, raising dwell will increase the bolt speed, making the marker handle paint rougher. However, because a higher dwell will let you run a lower pressure, it may be smoother and not handle paint MUCH rougher, but there are better settings for paint handling. A lower dwell setting will allow the minimum necessary force on the ball, assuming you keep your marker clean and well lubed.
You have to remember that the manufacturer has to account for all the mechanically disinclined people and kids that will inevitably end up purchasing their product and not properly maintaining it, so all axes/minis leave the factory set at a much higher dwell/pressure than what is actually needed, so that when you have more friction due to neglect the marker still works.
Sorry for the enormous post, wanted to answer that though
. This is all what I've noticed in my experience, it may not be universally true.
