After many experiments to get the speed and power just right I have discovered that by backing down the power when the laser is forced to go slower it would appear that there is a bit of an overshoot so there is less cutting as well.
On nice long cuts in 1/32" Baltic Birch between 400 and 380 speed at full power works pretty well but with lots of very small pieces the speed needs to go as low as 280 and still parts may need to work to free from the basic background. Even generally larger or smaller in a range can make a big difference.
