Reply To: Issue moving the Thor Robotic Arm

    Hi Brett,
    First of all sorry for the late reply!
    It sounds to me like that the current received by the steppers is not enough to move them and/or the acceleration of the steppers is too high. Try to give more current to the steppers (if you are using A4988 drivers there is a small potentiometer to tune the output current). If you have tunned the speed/acceleration parameters try to get them back to the default ones.Also check that the 12V power source has at least 5A-7A of current, otherwise the motors may not receive enough current to move the robot.
    Hope it helps!Angel LM
