Every time I use the 'switch 4 method' I can hear the stepper motor 'singing' while it goes through the routine.

Yes maybe does energise stepper but doesn't mean it's tuned correctly and still it doesn't set the Amps. Software is much better and takes any doubt away.
Also with a little tweaking you can get motors running much smoother than the autotune does.

I always get a pop up message telling me to do a 'Read' before I can do a 'Write'

Well yes suppose that makes sense really because you would want to read the drive for it's current settings before changing them.
It's been a few weeks since I've used Protune as I've been using EM806 drives lately which have supaceeded the AM882 and the software is differant so can't remember if my Protune does this or not.
