Ok we have confussion going on here because there are 2 ways micro stepping is shown or described. It gets involved but i'll try to explain quickly.
Typical stepper takes 200 steps to turn 1 revolution. Now Micro stepping is explained two ways either total Micro steps Per Rev ie 1600 or the number of 200 pulses ie: 8x 200. Both these mean the same thing.
So when your seeing 512 in manual then that means 200 x 512 =256000 micro steps per rev which is massive and you can never use.
Now you need 1600Ms so then you need to set Micro stepping in Protune software to 8.

Now where it gets confussing is the Dip switches on the drives relate Micro stepping Ie 1600.

Regards the Blown drive's then put that down to experience and keep to the safe rule of never unplug or plug-in anything while powered up.
