My H camera would not cal .......after selecting the gimbal cal function it would start its cal movements going up and to the left and stopping........retried several times........ and then just touched the gimbal and and started its movement again...... always stopping at the upper left same spot. Closer inspection found that the wires were binding from the twist done at factory........ I separated each wire replaced the bracket i removed for inspection .......tested gimbal cal several times and issue solved.............
