Finally tape the FFC down so it does not rub against the inner platter and press the IR
sensor firmly into its final place. You can optionally secure the IR sensor more
permanently by using the supplied double sided tape.
Once a reasonably accurate rpm indication is obtained you can move onto setting up
PID control and tuning the parameters.

Route the 8 way FFC connecting cable through the central bearing hole (or other
available access point). However, ensure there are no sharp edges to damage the
insulation of the FFC cable. Often the bearing bolt heads have sharp edges so endure
the FFC cables are routed in the spaces between the bolt heads.
Position the OLED case outside of the outer platter wherever you find it aesthetically
pleasing. Lightly tack down the FFC cable. Use either double sided sticky tape or a
couple of small balls of blue/white tack to stick down the OLED case. Connect the
other end of the 8 way FFC cable to connector P1 on the underside of the motor
controller PCB (silver contacts towards the PCB).
