  • Found that Pin 13 on the cold side diverter board is missing the pin. Tried removing the half-way stuck part of the pin, but it is not getting out of the way. If left in this state, it won't affect the setup, other than Pin 13 is not accessible for wiring.
  • We can still use the RoX thermometer (2-wire measurement). Re-solder purple wires to complete that connection (earlier, one of the purple wires was disconnected in the cold-side diverter board)
  • Will do 1d source mover test in room temperature to check for any issues today.
  • Fond this excel sheet for steps calculation, not sure which values to plug in.
