Aaron, If you look at what the commercial guys can do, you will see what the ultimate ceiling is for us hobbyists. I know the CNC Router from Haas (very high-end machine) can do 2000 in/min (850 mm/s) in fast slew mode. Of course, it can't cut at that speed. Anyway, I like to consider how long do I want to wait as the machine goes from end to end. In your case that is 100 sec. So how about 30 sec? Then you need about 3x from where you are now. Good luck!

It is set to run at 15mm per second max velocity, above that speed the steppers start screaming and miss stepps. I know that the screws, bearings and drive nuts are not that well aligned and whip about abit. I plan to fix that soon, but I would like to know what sort of speed I should aim for. Is there any one out there with a similar set up who could tell me what max speed they are working to.
