Currently - there is no way to adjust it. I do run the acceleration and velocity as high as I can. (on the emco it is in above 50in/s^2) I do have some math that calculates the following error of the shape (actual shape vs axis position) and decide how fast to run the spindle to get the tolerance I want. There should be some sort of trajectory planning - but that might be above my pay grade
