Troubleshooting: General Issues


#1

Motors don't move

  1. Run Actions->Test Motors
  2. If both motors fail, check that the power is connected and that the power is plugged into the Maslow shield, not the arduino controller.
  3. If one motor fails test, swap ports on the Maslow shield to motors to see if the problem moves with the motor.
  4. If the same motor fails, check connection at the motors to make sure the cables are plugged in correctly.

Wrong motor moves

  1. Make sure the cables are plugged into the correct port. For v1.1 and v1.2, the left motor (when facing the Maslow from the front) plugs into port P3 and the right motor plugs into port P1.

Timeout Errors Trying to Upload Firmware

Causes/Solutions:

  1. USB port conflict
    • Make sure the USB cable is firmly seated into the computer and the arduino controller.
    • Make sure that GroundControl is closed. It will seize the USB port and interfere with Arduino IDE
  2. Missing/Corrupted Driver
    • (Re)install driver for arduino

GroundControl Connection Time Out Error or Intermittent USB Disconnects

Causes/Solutions:
