The HKS power supply could not be repaired in a timely fashion. Ed and Jessie moved the cables for the Left Septum over to the BigBite power supply. Heidi and Jessie moved the temperature switches to the BigBite E-Stop interlock. It works. We turned the HKS supply on and left it in Local control, to complete the handshake interlock. We ran the BigBite power supply up to 1050 amps. It has a hardware current limit, so that is the highest you can go. So, the readback of the Left Septum now appears in the Right septum window of the Tools GUI. You control the BigBite power supply through the Right Septum controls. Sorry for the confusion, that is the best we can do given the time. May fortune smile upon the last few hours.
