    • Command: motor-expert-screen CXI:DG1:MMS:08 
  • If motor position doesn’t seem right, try to re-initialize first.
  • Set parameters(dial vs user):
    • Offset: set dial to be zero , maybe at limit switch, and user set at interaction point
    • Neg/Postive: since in y-direction, going positive actually is negative, so it is switched with these buttoms
    • Do not mess with, UNLESS comfortable: run current/percentage
    • Can move with velocity if experiment requires it
    • Velocity vs speed:
      • V: actual speed in ml/s
      • Speed: rev/s
      • Acceleration: requires calculations
    • If something is not moving: CHECK the comments given in the ‘log messages’
      • Power cycled error
        • Button will show to power-up
