Hi..Now that everyone has to stay inside (and also because we just got a young rescued cat!) I decided it was time to put together my MouseAir. Everything was fine until the servo check. When I run the servo test command, the servo only runs backwards two times. Is it possible that the leads from the servo itself are incorrectly color coded? I do have the orange lead to the left as in the diagram. Or is it possible that there is a programming error, as I thought the servo would first go forwards and then backwards.
Thanks for getting back to me so quickly. Here is a picture showing where the servo wires are connected, and the controller board is hooked to the grove board to one of the IC2 terminals (the one closest to the motors).
The servo test says: Moving servo on channel 0 0, press Ctrl-C to quit...
When I issue the command sudo python testLaunchServo.py the servo turns backwards about 1/4 turn slowly, then rapidly turns backwards about 1.5 turns, then repeats this before stopping. At other times, it does the 2 rapid backwards turns, but the slow ones are replaced with just a very slight movement of the gear with a "click".
When I run the ShootSequence test the motors come on and the Launch Servo makes one rapid turn backwards right before the motors shut down.
You were correct about the Launch Motor wiring. It was wired according to the photo, which is not the same as the correct hookup in the written description
I'm not sure it would help, but I could shoot a video of the Launch Servo in action.
Hi..I just received the replacement servo. Unfortunately, it still does the same thing. When running the testLaunchServo command, it only runs backwards two times. Either there is an error in the programming or the servo control board is not functioning properly. I have done all the troubleshooting steps; the green LED at the left side of the servo controller board comes on, and I even tried a different I2C slot. Are there other debugging steps to take?
Hi..I just received the new controller board (thanks for the extra mouse!). Unfortunately, still no joy. The servo when tested still rotates backwards 2 times. At no time does it move forward. What should I do now?
