I purchased the AL5D by Lynxmotion, and assembled it just like the assembly guide recommended. However, when I began testing the Servos to make sure everything was functioning properly, the Servos weren’t working. I asked around at work, and was told that I was likely getting a signal that was incorrect and that the motor was rapidly trying to move to far and then correct itself, but I don’t know how to fix it. I am not, in almost any way, greatly skilled at using controllers or servos. Anything else that is needed to help identify the problem, let me know and I can provide it.
Can you provide a few clear photos of your setup here (when you press reply, there is a grey section “attachments” just below the window. Please be sure to include clear photos of the connections and the board. What is working and what is not?
Here are some images. You asked what was working and what wasn’t, and I guess I would say none of them are currently. I have unplugged all 7 servos from the board and I am testing with the HITEC HS-645 MG currently. I plugged into some random locations and tried to move the motor using the software in the picture, but I got the same result.

The software does not indicate “found”. Can you press the COM button and select the appropriate COM port? Also, note that the default baiu rate is 9600, whereas it seems you have yours set to 115200.
Yes, sorry. I restarted the computer, and I forgot to change the settings before I snapped the picture. In all previous circumstances, I have been using the baiu rate of 9600 and it is currently indicating that it is found. It is still not operating normally.
Does the software detect the SSC-32U and both green lights appear in the IDE? If so, and you have your wall adapter connected to the wiring harness, with the On/Off switch turned to ON, and the red wire to + and black wire to - (ensuring the wires within the screw terminal are connected correctly and cannot be pulled out), what happens when you move the sliders?
I have posted a corrected picture of the circuit board and the software screen. This is what I started with at the beginning of this question. When I move the sliders in this configuration, the servo shakes and jolts like the gif I posted above.
Can you please check the following:
- Disconnect the servo you have currently connected and instead connect the one located inside the base rotate.
- Referring to the SSC-32U user guide, power the SSC-32U and press the baud button once and confirm the LED turns green (the other options being red, both green and red). This confirms the baud rate on the board is 9600.
- Retract the arm and connect to it via the software (Bluetooth button and Auto Com port) as before. Ensure the ON/Off switch is set to ON.
- Try to move the slider associated with the pin to which the servo is connected.
- If it does not move, do you see the LED associated with ‘B’ turn red when you move the slider, or does the LED associated with ‘A’ flicker green?
We await your reply,
Okay, so I disconnected the test servo and reconnected the base rotate servo. I checked the Baud rate using the guide provided, and it seems like I might have been using the wrong Baud rate, but even after I fixed this issue (upon checking now, the A/B just turns green to indicate the Baud rate is 9600), the servo is still jumping when I move the slider. When I move the sliders, immediately both of the red and green lights (on the A/B indicators) flash and then the A light just continually flashes green.
Your setup is simple enough that there is not a lot to change: SSC-32U plugged into computer via USB, power supply going to screw terminals with red to + and black to - (GND), a 6V wall adapter connected and the ON/OFF switch set to ON (please triple check that), and one servo connected to pin 0. The software detects the SSC-32U, and it is set to the right baud rate. Can you connect a different servo and see if the result is any different? If not, we’ll proceed with an RMA exchange on the board itself - contact us via the support center and include a link to this thread, as well as your order number.
