Hi,
We built JD according to the instructions and his left side does not work except for the claw. We double checked the wiring and all seems fine. At the moment we are at a stand still to make him function.
Thanks
You might want to double check that the ports that the servos are connected to are configured correctly within your servo control in ARC.
Are the servo cables connected to the EZ-B correctly (the right way around)?
What are you using to power JD? If it is a battery, is it fully charged?
I know you mentioned checking the instructions, but have you had a look at the Learn section for JD to make sure you have done everything correctly?
If it seems off balance you need to check and recalibrate and then possibly fine tune the servo profile.
Follow all lessons for JD in the Learn section, this will tell you the correct polarity for the servo wires, how to calibrate and how to enjoy your robot.
Also, all digital ports on the EZ-B are colour coded for ease of use. The black wire from any accessory needs to connect to the black pin on the EZ-B. This is also covered on many tutorial videos and lessons.
If things seem a little of balance, then like Rich mentioned you will need to fine tune the servos by calibrating them. The calibration links for JD are in the learn section but I have linked them for you below. Hopefully this will help sober JD up a bit.

Thanks for the feed back. All of the servos were fine except for one foot. Turns out you can only calibrate the plate on the servo not the servo in the foot. I attached an image. Also I tried to re-built bur the instructions in the ARC software don't let me restart the instructions, When I try to go back I get an error message as in pic attached. I can't get back to see what port each wire gets connected to.
In regards to the foot servo, can you not remove it from the foot casing to calibrate it? I though that you may be able to incase, for example, the servo ever needs replacing.
Also, have you tried closing the project and restarting it to get rid of the error message? If not You could also start a new project and get the assembly instructions up again.
No problem. Just to confirm, did you manage to remove the servo from the foot and calibrate it then? The only thing I can suggest then is change the servo position values for the unaligned foot servo for its standing, walking, dancing scripts ect, so that it straightens up and does what it should.
Or if you really do think it's deffevtive, maybe use the Contact us link and file a warrenty claim for a replacement foot.
