Question #: 14486

Question: I have a KL23H2100-30-4B motor with a KL-4030 driver and my motor stalls if I set the rapid above 180 imp.

Current Solution

What mechanical drive system are you using? If your mechanical drive system connected to the stepper motor causes the motor to spin too fast, then you will be reaching the torque limit of the motor under the load of your axis.

  • I have a KL-4030 stepper motor driver that I only have about an hour use on it but seems to be bad already. Has anyone out there had the same problem?

    The KL-4030 is a Keling 3.0 amp stepper motor driver. These are generally pretty robust drivers. You mentioned in the question that it worked for one hour. This sounds like it could be a contact issue with the wiring in the terminals. I would recommend that you check all of the connections. The terminals that are used in these drivers have terminals that are easily used incorrectly.

    Make sure to open the terminal all the way using a small screw driver. Then insert the exposed wire into the opening and re-tighten the terminal. Make sure of a good connection by tugging on the wires.

    Also, check kthe digital wires that connect from the driver to the control board.

  • I bought Nema 24 motors and driver package with usb board. What do i need to have more speed? Cant even jog past 25 ipm without the motor stalling (not having enough torgue)

    We recommend checking the dip switch settings on your drivers, having the correct microstepping/amp settings along with the steps/unit will help the motors run as effective as possible.
    This is a default parameter that we use while we test our motors:
    Driver dip switch settings will be at a 1/16 microstepping and 2.7amp (11001100) for x/y-axis and the z-axis will be at 1/4 microstepping and 2.7amp (10101100).

    In planet-cnc with increasing the motor speed, you will have to modify the settings in planet-cnc (File/settings/setup) you will modify the initial speed, maximum speed, and the acceleration.
    X/Y-axis step/unit: 1422.22 initial speed:500 maximum speed:750 acceleration:25
    Z-axis step/unit: 1600 initial speed:100 maximum speed:300 acceleration:25
    The initial speed and maximum speed will have to be roughly tested and adjusted per application.
    Make sure to adjust the JOG slide bard underneath the axis controls on screen to about 750, to compensate for your x/y-axis adjustments. If left alone the speed will max out at the default setting.

  • My plasmacam cnc machine has servo motors with an optical encoder to provide position sensing. Can the pokeys57 cnc controller and drivers run those servos?

    Yes, the Pokeys57CNC can control standard CNC or plasma machine servos as servo drives accept step and direction signals just like stepper motors.

  • I bought a, 3-Axis NEMA23 CNC Kit (36V/9.7A/382oz-in/KL-4030.but dont know how to set the dip switches on my drivers. The place I bout the kit from isent very good and support.

    That driver (not purchased here) is a standard 3.0 amp driver that will have the dip switch settings on the top of the driver. You will need to determine the amp rating of you motor for the scheme that you wire your motor to the driver (bipolar parallel is recommended in most circumstances but can depend on your power supply output). Check the stepping motor datasheet for your motor to determine this amp rating.

    The other set of switches will be configure the microstepping. This will depend on your mechanical setup (i.e. lead screw, rack and pinion, roller chain, timing belt, etc.) and the specifications of such mechanical parts.

    This general formula (which can be searched using the Customer Service Live with many examples): step/inch = (natural motor steps * desired microsteps) / (mechanical travel for one motor rotation)

  • 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.

  • With a 1/2 lead screw what is the optimal steps for the stepper motor driver 1/16, 1/8, 1/4 etc

    We typically use a 1/4 microstepping for lead screws, but you want to determine the microstepping only after you determine what resolution you want on that axis of the machine.

    The formula:
    Resolution is steps per inch or steps per milimeter

    I will go over this using steps/inch:
    steps = motor steps x driver microstepping
    inch = the amount of travel with one full stepper motor rotation

    In the case of our 1/2" 5 start 10 TPI lead screw, the axis will travel .5 inches with one stepper motor rotation.

    Let's use 1/4 microstepping (4 microsteps for each stepper motor step)

    Therefore:
    (200 steps x 4) / .5 inches =
    800 steps / .5 inches =
    1600 steps/inch

    Now let's use 1/2 microstepping (2 mistrosteps)

    (200 steps x 2) / .5 inches =
    400 steps / .5 inches =
    800 steps/inch

    Remember that increasing microsteps, the torque is also reduced, but the smoothness from the motor is increased.

  • I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

    Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

  • I am looking at 2 of your motor drivers. 1 is the 1/64 step and the other is 1/256. What is the difference between the two?

    Stepper motors are designed to move in specific increments; these increments are called "steps". For example, a common standard is for 200 steps per full revolution. Microstepping is a method to send signals to the motor to move only a fraction of a full step at a time. For example, if a motor has 200 steps per revolution and is microstepped 1/16, then effectively there are 3200 small step movements (microsteps) per revolution instead of 200 larger ones. This makes the motion of the motor much smoother and more precisely controllable, at the cost of decreased holding torque.

    Here are is a good references for stepper motor theory: http://users.ece.utexas.edu/~valvano/Datasheets/StepperMicrostep.pdf

  • 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
