There was significant hypothesizing over the reason the glueServo and platenServo would not move.

  • The USB plug was putting disruptive stress on the board and breaking connections.
  • The servos had been powered for 72+ hours and had burned out.
  • The airPump was declared as an OUTPUT and the command somehow interfered with the servo functions.
  • The servo.write(spd) values were not usable in this program.

The cause was that the Arduino shield was not firmly seated on the Arduino board. This was remedied and movement in all servos and the airPump was restored. The run time to lower the platen 1/16" was implemented.

The gap between the shield and the Arduino

To do:
  • Extend wires of waterServo
  • Make and install mount for waterServo
  • Correct + Install air tube
  • Test + Debug
  • Revise documentation
