Have you tried removing the "!" from the dir_pin?

From the docs,
"If the stepper does not move at all, then verify the “enable_pin” and “step_pin” settings for the stepper. If the stepper motor moves but does not return to its original position then verify the “dir_pin” setting. If the stepper motor oscillates in an incorrect direction, then it generally indicates that the “dir_pin” for the axis needs to be inverted. This is done by adding a ‘!’ to the “dir_pin” in the printer config file (or removing it if one is already there). If the motor moves significantly more or significantly less than one millimeter then verify the rotation_distance setting."
