Stepper Drivers

Hi All,

Recently got into the world of 3D printing. My first printer was a complete DIY Dolly Prusa i3 MK2 clone, I was recently gifted a makerbot replicator 2x and I am trying to build it up slowly, and carefully.

I have a mightyboard Rev H and I recently bought some TMC2208 v2.0 stepper drivers for it, I just cant figure out which direction they need to go in!

1) Do I need to resolder the heads? or is the 2208 the original drop in driver?
2) Which direction do the 2208's get connected?
3) Does this printer come with any documentation on connecting up the drivers, or is it all pre-built from the factory?

Thanks
