All magnets in eDT are set to 345 MeV/linac design values

Log Number: 4474952Logbook(s): Entry Makers: mockBody: 

For all magnets up to xBCD dumplettes.

I went through and double checked that all Box supplies and Quads are set to design values. There were a handful of quads set to zero but have now been set (made sure we were good to go in SRM first).

The only magnets not set to design are:

MXM3S03 shunt (see linked Ops PR). Design is setting current over limit.
MARC7A shunts as the box supply is turned off due to YBBS06 issues.

MXM3S03 shunt out of range at design setpoint

1 day 17 hours ago
Log Number: 4474951Logbook(s): Entry Makers: mockBody: 

Noticed this shunt 3.67% off design in eDT.
When setting to design setpoint, the control system is requesting 9.057 Amps but shunt throws a current limited alarm and limited to 5.266 Amps.
Put setpoint back where it was to not stress/damage shunt module.

Not sure if eDT is incorrect or the current limiting setpoint is incorrect.

Close loop tuned the cavity and saw that my KRRP increased tremendously even though my CRFP dropped by .4 kW when going +20 degrees.
