Please post your configuration files at pastebin.ca or a similar site, and post a link here. Your numbers describe a machine that is definitely out of the ordinary. A 30 meter long axis, and you cut at 4 millimeters per minute? That means 5.2 days to get from one end to the other. I hope your rapids are a lot faster than your cutting speed. Even if you can't post all of your config data right away, post your velocity and acceleration settings here. How well did you tune the servos?
