Awesome - the material removal rate is fantastic compared to the raster/offset paths I'm using out of Vetric and there's something very "right" about chips and the way they come off of the cutter.

2000mm/min doesn't sound too aggressive (I assume that's the rough maximum as iMachining varies the feed) - I was expecting 3-4000mm/min max, but as you say its No. 2 out of 8+ settings.
