At some point acceleration becomes the bigger factor if you want to overscan your engraving enough to get up to speed. I have not been focused on speed lately so I don't really know what the top end is.
Thanks for the input guys.
Yes, in my system I find that if I use speeds over 400 mm/s it actually slows things down a bit because most of the time I'm engraving across 2" or less increments. So in this sort of configuration, so in this sort of setting, if you increase the speed, the overshoots gets larger and the cumulative time increases due to that.
The reason I asked is that for laser 2.x, the laser head's movement is rotated 90 w/r/t to my current system, so the engraving path would now be very long, allowing me to make better use of a higher speed. Still working things out for my build, hopefully I'll catch batch #7 and get an order in before they sell out.
