Cal steps after nozzle tip change

[Common Spotted Cuscus]

Hi People,

Another issue with my wet noodles machine, is the toolchanger (and the whole z axis) is a bit sketch.
What I'd like to do after a nozzle swap is:

-Home Z only
-Go to Z park

-Visual home X/Y

-Z cal

-Nozzle tip cal over bottom cam

The last two steps are happening via available options. For the rest I suspect I could write a script for, which I have never done in openpnp. 
Can someone verify if this is a sane path to take and maybe point me to what's the best entry point to get this implemented? (E.g. are there an example script or something built in that I can look at, and it acts on some similar event doing similar tasks.)

Thanks!

Sorry for the unnecessary monologue. This was a lot simpler than I expected.
At least it seems to be working. 

For anyone who cares or wants to point out anything wrong in it:

Made a dummy actuator that has the homing gcode in it on actuation.
Then put this script in the scripts/Events folder as NozzleTip.Loaded.*.py 

from org.openpnp.util.UiUtils import submitUiMachineTask

homer = head.getActuatorByName("HomeZ")

submitUiMachineTask(lambda: homer.actuate(True))

submitUiMachineTask(lambda: head.moveToSafeZ())

submitUiMachineTask(lambda: head.visualHome(machine, True))

submitUiMachineTask(lambda: nozzle.calibrateZ(nozzle.getNozzleTip()))

submitUiMachineTask(lambda: nozzle.calibrate())
