Update - I found the Z steps/mm was set as 533.33mm/s and should be 2560!!
So I changed that and so far so good - it is currently printing a 20mm box in ABS. I can see it's not quite right as it prints but it's doing it anyway so I will let it finish then inspect/analyse.
One thing I have noted is that it first prints like a perimeter layer or two that is not the main print, before it starts the model it is printing. I'm guessing this is:
1) To ensure the filament is fed through and ready to begin, and
2) Gives you a chance to see if it's sticking to the bed or behaving right before it starts the model.
Is that the case?
When it begins both the perimiter print and the model itself I notice the plastic extruded is done in a very wiggly line. Does this indicate a fault?
