Thanks Eddy, last thing I want to do is fry a stepper as soon as I switch it on.

The AM882 drivers can be connected to a PC for set up. This lets you set an exact current limit (0.1A resolution it looks like from the screenshots) amongst other things.

The correct current is the current at which the motors don't get too hot, i.e. above 80°C. Generally the easy way to find this, as you've done, is to use the datasheet, but if you're not sure then you can just start with a lower current and work up.
