+Use the STEPPER_BUZZ command to verify the connectivity of each

+STEPPER_BUZZ command will cause the given stepper to move one
+millimeter in a positive direction and then it will return to its
+starting position. (If the endstop is defined at position_endstop=0
+then at the start of each movement the stepper will move away from the
+endstop.) It will perform this oscillation ten times.
