      Hey everyone,

      I am trying to figure out why my printer's movement is jerky/stuttering. Here is a link to a video of it homing X and Y and then going to the center of the bed to home Z.

      And here is a link to my Config files/Homing Files:

      Any help would be appreciated, I am not sure why it is doing this but it happens during printing as well when moving the axes.

        The reason is that you have loaded a height map and you have specified a very low Z jerk value (12mm/minute) in M566. The firmware is slowing down movement so that it can apply bed compensation without having to exceed the Z jerk limit when it needs to change the rate at which it applies Z compensation. Try increasing the M566 Z value.
