CNC Shield V3 External Stepper Question

ric812:
To the left of the c1 driver socket, right below the reset button there are a set of yellow/blue pinout that start en/grd, x.step/dir, etc. I am just trying to get the step and dir to the tb6600.

Those pins seem to be clearly labeled. As well as step and direction you will need a GND connection.

Where does the TB6600 get its 5v power from? Some drivers generate it from the motor power supply, others need a separate 5v supply.
