    Default BREAK OUT BOARD HELP

    I’m trying to wire the steppers, motors and BOB for a cnc router still the school I’m teaching
    The motors ARE wired to the steppers now I need to complete the wiring to the bob.
    Since it was sold to me as a 6 Axis board, I can’t figure out where the wiring goes.
    Of course some is printed in Chinese.
    I’ve managed to locate the wiring for the motors to the KL’s but I’m confused about the rest.
    I’ve watched countless TouTube videos....
    But I’m not sure.
    5V, 24V.... checks out on the BOB.
    So how do I power the KL’s?
    Is it 110V or is it 24V or is it 5V? And how do I do that?

    Just looking at your photo of the BOB I can not read all the labels but

    I can make out you have the 12 outputs ( pins 1 to 9 + pin 14 + pins 16 & 17 )

    the question is how many axis do you need ?


    you can use all 12 outputs to drive 6 axis but you will then not be able to control the 3 relays !


    if you only control 4 axis you will have outputs to control other things

    you will have 3 pins available to control the relays -

    the BOB has 3 jumpers you need fitted when using the relays -
    the jumpers should be lablled to indicate which pin controls each relay


    and a 4th pin to control the spindle speed , if the BOB has a PWM to analogue converter


    you should have 5 input terminals labelled pins 10 to 13 +15 or possibly IN1 to IN5 !
    to connect your E-stop switch and home / limit switches

    so far I have not found any instructions on line

    Thanks for the reply.
    I don’t have the part I front of me, but in order to hVe control of the 4th axis, it appears I need to purchase one more KL step controller or whatever it’s called?

    Just wondering what picture would help?
    I’m back in school Tuesday and can reload one for you.
    But you have to understand, I don’t speak this language so it’ll be more like...”get a red wire... connect it here,,,, and so on and so on.
    Thanks again

    The other thing I thought of, if I called you and maybe did a Face Time, or just sent you pics via text and we could talk.
    I’m in Pennsylvania at St. Gabriel’s Hall.
    It’s a school for delinquent, troubled youth that are court ordered up to 24 months.
    I’m trying to start a STEM program to show you can make great money by NOT-selling dope.

    Hi robwiacek

    how did you know how to wire the unipolar motors to the bipolar stepper motor drivers ?

    did you have a data sheet for the motor to know which 3 wires goes to each coil ?


    high resolution photos of the labels next to the BOB's terminals or a link to the data sheet will help

    I do, I looked up the diagrams on Anaheim Automation (I think)
    I’d like to send you a pic of the actual wiring on the units
