Could you draw a wiring diagram for external drivers and the rpi cnc shield? Great build!
C-Beam Machine - MyFirstCNC
This is my first foray into CNC machines, after much review I decided on the C-Beam machine as it seemed easy to work with and will enabled me to build more and larger machines as I gain knowledge. I am planning on building the machine largely unmodified from the reference design. I will be building the machine an axis at a time as I need to spread out costs over time.
