A hexapod also has joints, and these must be coordinated precisely or the machine can bind up.
On machines with non-Cartesian axes, LinuxCNC allows the machine to be set up in joint mode, where each joint can be moved independently, such as during homing and initial machine alignment. Then it can be switched to "world" mode, where it responds to Cartesian and rotary coordinates, and the kinematics determines what the joints need to do to put the tool at the commanded point and angle. I'd probably better stop there, as I know only a hint about these machine. Jon ------------------------------------------------------------------------------ Better than sec?
