Rambo 1.2x board

So I am getting ready to build my large printer and I want to use 24 volts for large bed , etc.

My question is how much amperage can a Rambo board accept and send out ???

Also, I want to use Nema 23 steppers for x y and z. I see ones rated for 1 amp and higher.

How much power can the Rambo send out per coil ???
