I am having trouble with getting the servo to extend.
I have a 2S HV High Speed Metal Geared Antweight Servo and a 7.4 V 2S battery and I need the servo to be able to extend beyond 60 degrees to help my robot self right.
Whenever I plug the extender between the receiver and the servo, the servo doesn’t move when I turn it on and only succeeds in heating up to unsafe levels, even when I correct the fault in the first picture and ensure the signal wires line up.
What can I do to ensure the servo goes the full way?
Hi Leo! I don’t have experience with that servo extender, but is the servo plugged in the right way round? The BBB site doesn’t show which way round it should be, but I’d expect the ground and signal wires to be on the same side at both ends of the board.
If thatt is the correct way round, which radio channel are you running the servo on, is it an analogue channel or a switch? If it’s a switch, it’s possible that the extended range is too much for the servo and it’s running into an internal endstop. See if it works on an analogue channel, and then wind your switch endstops all the way down before plugging it into the switch channel.
I have also messaged BBB on insta and they told me that the fact it was ever done the wrong way round in the first place, like here, is why it failed. I will get another extender to check that this is the issue.
On both servo and receiver (Rx) sides match the colours with the following:
White = Signal (goes to yellow on our servos)
Red = Positive (goes to red on our servos)
Black = Ground (goes to brown on our servos)
