    G0704 ELECTRONICS HELP!!!

    I have the Hoss Heavy duty package.

    I have hooked everything up per the kl-5056 diagrams, and I have set mach 3 up properly.

    I can hear a high pitch from the stepper motor but it will not turn.

    Does anyone have any pictures of their set up that I can look at to make sure I'm setting everything up right?

    My WAG (wild a$$ Guess) is you are driving the motor too fast.

    Try single stepping and/or disconnect the motor from the shaft until you get it going.

    I would suggest carefully checking your wiring. The problem sounds very much like a prolem I experienced with my CNC coversion when i had two wires reversed. Check, also, that you have no nicks in the insulation that might cause two leads to be shorted together. Although this may seem obvious, check than none of the wires are loose. Good luck!

    I agree -checking your wiring is the first step. It's best to test everything laid out on the bench before assembling the parts & pieces. Make sure the charge pump, if in use, is configured correctly, along with any limits that may be enabled. You can disable limit checking in Mach3 to simplify things to start out with.

    From your photo it looks like you are using light gauge wire between the motor driver and the motor. You need HEAVY gauge wire there (AWG22 or less), otherwise you get too much resistance in the wires and a large voltage drop so the motor is starved of power. I would recommend a shielded cable (go to gekodrive.com for their shielding and ferrite core recommedations). The digital signals between the breakout board and the motor driver are not high power signals so you can use much lighter (AWG26-28) there, so your heavy wire there is a bit of an overkill. You are good with the heavy gauge wire between the power supply and the stepper driver. Give that a try.

    Those are the wires on the motor itself, so I think it's safe to assume the wire gauge is adequate....

    Which steppers are those? I noticed that some of the Keling steppers have the A and B on different colors amount the 570Oz-in series.

    The jumpers on your driver all seem to be up, switches 1,2,3 should be off,on,on for the 570 stepper.
    switches 5,6,7,8 need set for your preferred microstepping
    for example, off,on,on,on for 1/2 microstepping.
    You have the step and dir + connected to the c10's common, Is the jumper
    on the c10 set to make the COM terminals +.

    What do you have your switches set to on the driver, the little arrow to the left tells you which way is ON.
    You'll want them set like I said above.
    The sample pic is not what you want either but that's what I found online.
    Sw1 - off
    Sw2 - on
    Sw3 - on
    Sw4 - off
    Sw5 - off
    Sw6 - on
    Sw7 - on
    Sw8 - on

    In your pic, Is that a 570 oz/in nema 23 motor?
    If you're using the heavy duty package the Z motor is nema 34, asking because you have the driver
    connected to pins 6 and 7 which are typically for the Z motor.
    Is mach 3 set to use pin 6 for step and pin 7 for DIR as you have it wired?
    Try unchecking step low active in ports and pins, keling shows it checked in their config but you may need to have it Xed instead.
    Is the LED flashing on the driver or solid green, flashing on mine meant too much voltage was being supplied from the power supply.
    Also, can't tell from your pic whether there is a jumper on the c10 from the +5v to the enable pin otherwise the outputs won't work.
    Saying you "tried everything" isn't good enough feedback to help here.
