+but it had not moved since the reset, 
+suggesting the encoder value position was incorrectly initialized.

+When the ATSpectrograph is first initialized after a power reset

+when it tried to position the stage at +67mm), 
+since the encoder position is incorrect 
+the stage cannot arrive in position and times out during the move.
