Ultra MegaMax Dominator (UMMD) is my coreXY 3D printer. This video shows a test print in which I cranked up the acceleration in X and Y to 10,000 mm/sec^2, print speed for all features set to 200 mm/sec. At this acceleration, it only requires 2 mm in a straight line to get the speed up to 200 mm/sec.
I put in lots of jerky movements in an effort to get the mechanism to start shifting layers, but it still maintains layer registration. It looks like the extruder is not quite keeping up as you can see in the rough infill of the print.
This is much higher acceleration and speed than I will probably ever use- print quality suffers a bit at these settings, and the machine shakes and rattles.
