Firstly, sorry if this is answered already, i searched but did not find what i think is the problem.
I've just received a Bittle kit and am going through the initial calibration.
One joint (front left elbow) is not moving.
(with the joint disengaged, watched the set point on the gear to confirm it is not moving at any point)
I swapped servos and confirmed that the servo works when connected to another joint, and vice versa is true as well, any of the servos connected to port 4(?) it stops working.
All black wires are on top.
It would appear that port 4(?) is not working.
Is there an easy way to swap it for port 2 (the open port behind the head port) instead?
Thanks in advance, and i'm so exited to start playing with this amazing project of yours
