Daily Shutdown
===============

These procedures are used for shutting down MagAO-X at the end of a work day.  

Minimal shutdown
----------------

This procedure can be used if you expect to startup in a few hours, right away the next day, etc.

The main goal here is to shutoff "the expensive stuff".  Namely:

 - dmtweeter
 - dmwoofer
 - dmncpc
 - camwfs
 - camsci1
 - camsci2
 - camlowfs
 - ttmmod
 - ttmpupil

Rules:
 - do not power off a DM unless it has been released
 - do not power off a camera unless its temp is 20C or higher
 - do not power off instcool!
 - steps can be done in parrallel, so start warming up cameras, go on, then come back
 
Cameras (each of camsci1 camsci2 camlowfs camwfs):
 - close the shutter
 - warm up to 20C (use cameraGUI, change setpoint)
 - wait for it to finish
 - power off
 - note: for camlowfs, power off under both pdu1 and usbdu0.

dmtweeter:
 - open the loop
 - press "loop zero"
 - zero flat
 - zero all ch
 - release
 - power off

dmwoofer and dmncpc
 - zero flat
 - zero all ch
 - release
 - power off

ttmmod:
 - if modulating, first press set in Pupil Alignment GUI
 - press rest
 - power off in Power GUI

ttmpupil
 - press rest in Pupil Alignment GUI
 - power off

Additionally:
 - power off camtip (its just a heater)
 - power off source
 - power off tableair

Remaining devices such as focus stages and filter wheels can be left on, which will make alignment easier next time.

Standard Daily Shutdown
-----------------------

If MagAO-X will be unused for a longer period of time (say a weekend), we typically shut down everything but computers, networking and cooling.  

At the end of this, the following things will still be on:

- pdu0.compicc
- pdu0.comprtc
- pdu0.dcpwr
- pdu0.swinst
- pdu3.blower 
- pdu3.fanaux
- pdu3.fanmain
- pdu3.instcool 

**Note:** it is critical that you not shutdown instcool while compicc and/or comprtc are on!

Follow the steps in "Minimal Shutdown" above. Also do the following.

fwtelsim and fwscind:

- first power off on usbdu0
- then power off on dcdu1

Everything else (except the items listed above) can be shutdown in any order.  Occassional errors in the logs during shutdown may occur.
