Question #: 1161

Question: I have theNema 24, 425 Oz stepper motors kit what are my Ports and Pins?

Current Solution

The ports and pins are designated by the breakout board that you have, Now here are the schematics for both(https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/ and https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/) Which for the Parallel the pins will be 1,14,2,3,4,5,6,7,8,9. For 1,14 you will need to use them together for a additional axis. Setup will be (ex.mach3) step in (2) / direction pin (3). continued for other pins, 4,5 6,7 etc.
Now for the USB it has the label on the board right next to the terminal blocks, x-axis/etc.

  • I am asking what to set my steps per using your kit stepper motors and a 1/2"x13 lead screw with Mach3

    Here is the formula for steps/inch (steps per inch)

    Steps = how many steps for a full ration of the motor = standard motor steps x number of microsteps for each step
    Standard motor steps for our stepping motors is 200 steps per revolution.
    Microsteps are selected on the driver and are shown as full, 1/2, 1/4, 1/8, 1/16, 1/32 etc... Use the denominator for the number of microsteps per step.

    Inches = how far the travel is for one full rotation of the motor. For the 1/2" - 13 TPI (threads per inch), the travel length will be 1"/13 or .076923". So, for one revolution of the motor, the travel distance will be .076923 inches.

    So, the steps = 200 * microsteps, let's make this 1/4 just for the formula.
    The inches will be .076923. Plug those into the formula:
    Steps / inch = (200 * 4) / .076923 This can also be written as:
    200 * 4 / (1 / 13) = 10,400

  • Have checked stepper motor wires dozens of times and they are wired like diagram says. Stepper motors will not turn under power. I am using laser control option. What should I do?

    This sounds like a problem with the step (pulse) signal. The driver motors receive two signals from the computer via the board -- one is high or low and tells the motors which direction to turn, one is a square wave pulsed signal(quick that tells the motor to turn or a constant high signal that tells the motor to maintain its position. With an oscilliscope you can check for proper signal at the board. If you bought the board from us, please contact us to arrange a return authorization.

  • delivered Stepper motors do not have the same colored wires as book/videos. What wires to to connect to what?

    You will need to use the datasheets or instructions on the product page of the actual motor you have. For instance, if you have the 425 oz-in motors, you can go here: https://www.buildyourcnc.com/item/electronicsAndMotors-nema24-425ozin

    Click on the link for the datasheet, or look in the instruction steps and you will find a wiring diagram. If the datasheet gives you an option for bipolar parallel connection scheme, use that one, otherwise, there is probably only one diagram, so you will need to use that one.

  • With the Mach3 USB board, my stepper motors are moving or spinning slowly.

    If your motors turn very slowly using your Mach3 USB board, then either the pulse from the board is being output at a slow rate or the motor drivers are set to a higher than expected microstepping:

    The Mach3 USB board outputs the pulse rather than the computer, but Mach3 controls this pulse frequency within the motor tuning section. First, determine if the travel distance is correct with the computer and the physical travel of the machine.

    If the travel is different, then your stepper motor driver's microstepping is incorrect, or the steps per inch/mm in the motor tuning within Mach3 is incorrect.

    If the travel is correct, then simply change the velocity and acceleration parameters to your desired level. If Mach3 will not achieve the velocity you desire, then decrease your stepper motor driver's microstepping setting, readjust the step per inch/mm in mach3 and readjust the acceleration and velocity to your desired levels.

  • I HAVE ONE OF YOUR SMALLER STEPPER MOTORS RUNNING MY X AXIS BRIDGE CRANE AND IF IT IS MOVED TO FAST THE MOTOR SOUNDS LIKE SKIPPING STEPS WILL 651OZ REQUIRE A DIFFERENT POWER SUPPLY CONTROLER?

    Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

  • If I use a Porter Cable 3-3/4 router motor what size stepper motors do I need?

    You can use the standard electronics combo: http://www.buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo. The size of the stepping motors are generally sized with the overall machine structural weight, inertia of parts, the type of mechanical parts used to move the axes, and actually, less by the router which is more connect to how the machine is controlled.

  • Hi I have a Proxxon MF70, I want to add 3axis stepper with controller and software by USB. Can you suggest a kit for me? Thanks.

    To implement a electronics combo to run you Proxxon MF70, you will need to find the correct drive components (ACME screw, linear rail, etc) and look into any specific modifications needed to your rig.
    I would recommend the USB 3 Axis Large Motors Electronics w/ USB Interface Board.
    Since the machine is metal, our larger motors would be highly recommended.

    We have not done this conversion, through research is recommended.

  • Your book built stepper motors have different wiring colors than what you have in your instructions about pairing the wires. Do you have an updated version?

    Our book is a bit outdated with our current stepper motors we have for sale, however the motors recommended for our scratch build kit (same as in book) is our 425-oz motors with 8 wires (https://www.buildyourcnc.com/Documents/PN.SM60HT86-2008BF-U%20(inhouse%20PN.60BYGH303-13)%20(1).pdf) now you will join the 8 cables in pairs that will convert it to 4 wires. Wiring: Red and Blue to A+, Yellow and Black to A-, White and Brown to B+ and Orange and Green to B-.

  • I'm building my own machine using your motors and drivers. What is the best dip switch settings for the 3.0 amp drivers powering the 425 oz motors

    The settings that you will use for your 3.0 amp driver to properly power and turn your 425 oz-in stepper motor will cheifly depend on your application and the mechanical parts you are using on your machine. In all circumstances, the amp setting for the stepper motor (according to the datasheet) should be 2.8 amps. Use the closest setting on the driver without going over.

    Here is a good rule of thumb for the microstepping which will correspond to the resolution, but wil also affect torque. You always want to try to achieve the best torque and resolution for the axis you are moving but go with the lowest microstepping possible. In cases where there is mechanical advantage, like a lead screw scenario, where for each motor revolution, the axis move a very small amount, you will want a very low microstep value. This is because the mechanical configuration will provide most of the finer resolution and you will not need the microstepping to assist in this. Increase the microstepping only in conditions where the axis is not moving smooth enough, or where there is a mechanical disadvantage. A mechanical disadvantage would be where the stepper motor is causing a great amount of movement in the axis and the resolutions suffers from this condition. Increase the microstep value up to your desired resolution, but don't go over since the torque of the motor will decrease.

  • Are the stepper motors on x and y axis suppose to be hot after running for approximately 30 min. I can touch them but they are hot.

    If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed.

  • I purchased a 3040 CNC router off eBay a year ago and would like to change the controls. The steppers are 185oz.in motors. My question do i need to purchase a interface board and break out boards?

    When dealing with 3rd party machines, we have a universal setup that will fit almost any other machine, although please take in consideration the specifications in which your stepper motors and drivers are used and set to!
    Now changing the controls, would be more or less changing the Breakout board/interface board to a different one that might use a different program to run your machine. Usually you will not need to change your interface board or breakout board, unless the 3rd party manufacture made it specifically to that set up.

  • How can I have two stepper motors on one axis

    Yes, you can use 2 motors in the same axis output, however you will still need a driver for that motor! Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

    Also you can run a slave motor using another axis on the board, and setting it up in the Planet-CNC settings.

    Planet-CNC/File/Settings/Axes, here you will enter 3 in the Number of Axes location, and then change the Function of the Axis 4 to Slave 1. There you will have the 4th axis or A-axis be a slave for the x-axis.
    Slave 1 - X-Axis
    Slave 2 - Y-Axis
    Slave 3 - A-Axis
    Slave 4 - B-Axis
    Etc...
