Question #: 14261

Question: How do I wire two stepper motors for one axis?

Current Solution

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...

  • How long does it take to ship to Israel 3 nema 11 stepper motors ?

    Unfortunately I am not able to give an estimate of shipping time. This is because there are multiple shipping options, Some of them cost more than others, but ensure the package arrives in a certain number of days. Others do not give a number of days, and many factors could change the length of shipping time, such as weather, or busy season. It would be best to choose an option you are comfortable with the price of, and then Google search the typical times it takes for that option to get to you, or call the shipping company and request that estimated time from them.

  • I ordered the 3-axis medium stepper motor kit. The drivers i recieved were those for the 3-d printer main board, not the modular ones. How am i suppose to wire that up now?
  • I'm going to use 2 stepper motors for my X-axis. Can I use the same connections on the B/O board to do this knowing I will need 2 separate driver boards.

    Yes, absolutely. If you need two motors for a single axis, you will want to use the same terminals for pulse and direction from the breakout board.

    More specifically, you will wire the step/pulse pin to both drivers, and the direction pin to both drivers. If the motors need to turn in different directions, simply swap the A and B coil connections on one of the motors.

  • got my stepper motors wired to the information on your website using USB Bob and the motors don't step they keep turning like an old drill until they stop

    So, if I understand correctly, the stepping motor will turn on command, but the motor will only turn in one direction. Check the output of your direction signal wire. Check the wire voltage when you command the motor to turn on one direction in the planet-cnc software. Then check the voltage when you command the motor to turn in the other direction. The voltage should be different in each case.

  • how to calibrate stepper motors with ballscrews In mach3

    The easy way is to use Mach3's calibration process to calibrate the axis with the ballscrew coupled to the stepper motor. This is done in the settings tab of Mach3 and clicking the button just above the "Reset" button called "Set Steps Per Unit". A dialog box will appear asking how far you want Mach3 to move that axis. Mach3 will move that axis at a distance that is determined by the existing steps per unit value set in the motor tuning dialog box (config menu -> motor tuning). Not knowing the distance that this axis will travel, it's best to use a very small value.

    The more difficult way and the technique that should be used to create the initial value for the step per unit in the motor tuning dialog box. Use the steps/unit formula. This example will use inches.

    Steps/Inch
    = ((motor natural steps) x microsteps) / (the travel for one complete revolution)

    The travel for one revolution would be the distance a ball nut will travel with one complete turn of the ball screw. This is generally the number of starts / threads per inch. Say the ball screw has 5 starts (5 threads starting from the beginning of the screw) and 10 threads per inch (TPI), then the travel for one complete turn of the screw would be 5/10, or 1/2".

    Say you set the microstepping to be 1/4 on the stepper motor driver and your stepper motor has 200 natural steps per revolution (1.8 degrees per step), then the total steps would be 200 x 4 = 800.

    So, the steps/inch is 800 / 1/2" = 1600 steps per inch

    Hope that helps

  • 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.

  • Hi please could you tell me how to work out the size required for the stepper motors ? which kit to get thanks

    The size of motors required for your machine build will depend on many characteristics of the machine.

    If the machine uses a gantry (rather than moving the table bed) and the weight of the gantry (specifically with inertia),

    The mechanics used with the axes, lead screw, roller chain, timing belt or rack and pinion. Generally you will need less torque if using lead screw due to the mechanical advantage, but friction is important to consider.

    If you are building a 4'x8' or larger machine, it would be best to use: https://buildyourcnc.com/item/electronicsAndMotors-3axis-heavy-gantry-elcombo

    Otherwise: this electronics: https://buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo should be fine for most configurations.

    If you feel that you need extra torque on the z-axis (the z-axis will use a very heavy spindle, for instance), use this electronics: https://buildyourcnc.com/item/electronicsAndMotors-3axis-651-elcombo

  • From the BOB how can I reverse one of my steppers - i'm running 2 on my Y Axis

    When trying to use two motors on a single axis, there is a multitude of methods to get them to work together.
    First: There should always be a slave option in the CNC control software(mach 3/ planet-cnc/emc2/etc.), this will be the easiest way to make the dual motor configuration work. However some adjusting might be necessary due to the orientation of the motor when mounting it on the opposite side of the CNC machine.(Mach3/config/slaveaxis, planet-cnc/file/settings/axes).

    Secondly: Dealing with our interface boards(maybe third-party as well), you can have two drivers going to the same axis on the interface board. Which then will have one motor per driver, this will use the same motion and control from the (ex.) x-axis to driver two motors. However some adjusting might be necessary due to the orientation of the motor when mounting it on the opposite side of the CNC machine.

    Adjusting of the driver or motor wires, can be done separate from the control software with the use of a hex inverter, that can be used and to switch the signal (ex. takes a low signal and brings it high, and takes a high signal and brings it low) of one of the motors, to run the same as the other motor.
    There is also another method of inverting the orientation of the motors movement without the use of a hex inverter. This method you will have to wire the coil's of the motors oppositely of what is recommended for one of the motors. Example, you will wire our Nema 24 as follows(recommended): A+ - red/blue, A- - yellow/black, B+ - white/brown, B- - green/orange. However to run another motor with with it you will have to switch the A/B connections to: A+ - white/brown, A- - green/orange, B+ - red/blue, B- - yellow/black.

    These method's are usually needed/used when trying to control two motors and setting it up without the help of the CNC control software, and also due to the mounting orientation of the second motor, the inverting the direction of motion will be necessary so they work together instead of working against each other.

  • 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.

  • How do I wire to nema 23 motors parallel

    Wiring two motors in parallel is pretty easy.

    Here are the steps:
    - You need to have two stepper motors and two stepper motor drivers.
    - Each stepper motor will be connected to its own stepper motor driver.
    - Both stepper motor drivers are connected to the same CP and CW pins on the interface so the same signal is delivered to both drivers.
