I am building CNC router what can mill a Alu/Some lighter metals/Wood
Table is 1200mm X 700mm and work area is 900mm X 600mm
Table is made from steel and quite heavy, design is similar like here: http://www.cnczone.com/forums/attach...6&d=1122266696
So i plan to use nema34 3N/m steppers to archive good speed and torque
But this steppers takes 6A to phase this means what I need descent driver board.
I found on ebay this driver so what you think about that is it OK?
