I
think that the accel in the motion control software wants to have the accel for
the machine - Depending on how the servos were sized the accel limits for both
axis might quite close anyway. You need the Y axis to behave like the X axis or
otherwise you will get funny motion as the speeds increase. Accell determines
how the machine will react when starting a move as well as when cutting radius's
(radii). If the accel value is to high you may not be able to stay on path as
travel speeds increase - if the accel is set to high the X axis lag will cause
problems on dual axis motions - too much lag.
