Ok, time for an update.

Had some setbacks with some of the electronics items, not going to discuss as such but many thanks to continued offline support from both i2i, JazzCNC and Gary @ Zappautomation.

Received my compressor today as well as the solenoid / actuator items. Got mostly working, missing 2 small 90 degree items, but its installed and wired up.

I tested the carousel motor for the first time today, spins along happily. I have no real idea yet how it knows where it is. I know there is a sensor, will try and look at that again later and there is an ability to reverse the direction of travel. Clearly it needs to 'know' which tool is currently selected.

Am hopeful that this weekend, unless I have issues or some delays on parts coming in, may be able to do the the first basic milling, with or without the tool changer working.
