When using the laser controller, what does "engrave beyond border limit" mean?

LaserCAD: Engrave beyond border limit. This is caused by a sweeping motion that is too fast and where the acceleration is too slow. My recommended action would be to keep the acceleration the way it is and slow down the speed of the engrave sweeping motion. I typically use around 200-300 mm/sec and make sure that the axis sweep motion is the nozzle along the gantry, not the gantry itself. The gantry will have too much inertia to sweep, but the nozzle is very light and can sweep very quickly. Specifically, what is happening with the engrave beyond border limit is where that axis is not able to slow down fast enough to not hit the border. For instance, imagine a car going 100 mph and it needs to stop within 30 feet. This would not be possible because the deceleration is not high enough.
