Re: PlanetCNC PoStep60 Stepper Motor Drivers
If you can solder, my THB6064AH kit will get close to that. 4 amps sustained with a good heatsink. And $32 each in sets of 3.
psst: several people have pushed them to 5 amps
What? Who said that! Never push a driver past it's specs! ,o)
Check the user gallery of working machines for the sort of work these drivers can do:

if they can 3D print a castle out of concrete big enough for an adult to live in, then they can manage pretty much any CNC machine.
