Insert an Allen wrench into the end of the θ-axis pulley of the head edge, and
then turn it around 10 times or more
●It has no problem if showing no variations in the rotational torque.
●If showing some variations in the rotational torque (Rotational resistance can be either high
or low sometimes while turning it around), contact us.
●Two θ -axis motors are located on the right and left sides. Inspect both of them.
