Shown here is a wiring diagram of my drives and power supply. I'm confused on how to wire the drivers from the breakout board. Do I use the 5 volts ( switchable for com to 5 volts)from the C1 board to the Step+ and Dir+ or use the tap off the power supply? Do I then hook up my Step and Dir terminals from the BOB to the Step- and Dir- on the driver board? I can use all the help I can get. Wiring is not my thing!
