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

    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.

  • 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.

  • 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 two stepper motors for 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...

  • 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

  • stepper motor runs smooth then rough for a moment then smooth, etc. Does this at all steps, and connected motors.

    This sounds like it could be a loose wire, or poor connection with the motor wires. Make sure all wires that are to be connected to each other are soldered and use a lineman's splice when putting the wires together. Also, make sure that the wires going into the driver is securely fastened.

    If this is an issue where the motors have run well for a long time then just started to show this performance issue, then make sure that there are no wire ties or other binding method that is chaffing the wires. This would make the motors run oddly at certain travel positions where the chafing has caused a short with the wires.

    If this is an issue where you don't have the motor plugged in at all and are just trying to turn it by hand and this phenomenon is occuring, then make sure all of the wires are not touching each other. When wires are touching each other and you are trying to spin the shaft by hand, the motor will feed current back into the motor making it difficult to turn.

  • Are the motors for the 5x suppose to operate at a high temperature?

    Yes, all of our stepper motors will run hot, depending on the way it is operated. Energy comes in a few forms, light, motion or heat. If the stepper motor is not moving, it is typically holding its position, which will cause the energy to transform to heat energy. If the stepper motor is holding a load, and is moving, it is drawing more current and the energy will be in the form of heat and motion.

    It is totally normal for stepper motors to be hot to the touch.

  • 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
