    Got my first driver and stepper in the other day so I'm trying to get them wired up but I'm drawing a blank on this.

    I have a ST-M5045 driver
    http://www.sainsmart.com/zen/documents/20-019-209/ST-M5045 Instruction manual.pdf

    and a Sainsmart mach3 breakout board
    SainSmart 5 Axis Breakout Board for Stepper Motor Driver CNC Mill 3D Printing, Arduino, Robotics | Sainsmart

    The area i'm having trouble with is that the driver has 6 wire slots for the control board and I'm only seeing 4 per stepper on the controller.

    I think I'm supposed to connect

    EN -->ENA(-)
    DIR-->DIR(-)
    STEP-->(PUL(-)
    +5V-->?
    I'm assuming that all the negatives are common(COM?) ground?
    I'm not sure what the 5 volt positive is supposed to go to. Is VCC in the driver documentation+5V?
    EDIT: looked a bit closer at the driver diagram and realized that the controler connections connected to the negative end....and it looks like I'll need a 240 ohm resistor for 3 of the connections?

    It says no resistor at 5v, 1k at 12v and 2k at 24v. The 240ohm is internal and already built in. The minus is common.
