I think I finally have some useful progress at last!
New PSU and it seems to be behaving far better, and have moved the carriage & bed to their end stops before switching on. They behave quite well now.
I think the end stop on the z axis needs tweaking still.
2 issues I think now.
The bed doesn't appear to be heating (bed temperature shows as -33C at room temp of about 13C), and the extruder doesn't appear to be feeding/retracting, despite going past the default temp for it to be enabled.
