I was wondering how I could check that.. I don't know - but I can tell you this.. At G64p.002q0 P is in mm and my config. 30in/s^2 and 500ipm per axis..
the velocity just starts to dip - just wiggles between 3000 and 2999mm/min. If I do p.001q0 it fluxuates around 2200mm/min. The accelleration graph looks a but harry at that thoug though.. (wipping around to try to keep up the path tolerance and velocity up..) this is p.002q0 http://imagebin.org/300880 this is with a sane-ish p.01q0 http://imagebin.org/300881 so with the path programmed - it can follow at cutting speed with tollerances below what is sane...
