  • Removed stiffening ring for the flipping
  • Joined siggen cables
  • verification RB to CP distance with dial-gauge for excluding RB degluin:
    min gap: 6.25mm, min gap: 5.95mm. Minimum specified: 5.97mm. For 2 hundreds of mm we decided to not move the actuators giving a change of force calibrations. Data are reported here (Excel file).
  • First Attempt shell installation:shell installed.
  • Found 2 actuators with problems: DSP#54 (in) and #455 (ext)
  • #455 problem with flat cable, changed. working back
  • #54 problem (half signal?) recovered pressing the distribution board and reconnecting the flat cable.::
  • Touch analisys: improved touch analisys. Dust removing has to be scheduled.
  • Siggen crate #4 (modified by Roberto) gave wrong signal. Disappeared switcing on and off. Seems to be raletaed to grounding problems.
  • FF matrix acquisition started (run overnight). modal 5 iterations.
