  • Do I have to use the Postep Driver with the Pokey57CNC usb/ethernet board. Can I use the Motor Driver (24-40 volts DC, up to 3.0 amps, microstepping from 1 to 1/64) With The Pokeycnc USB/Ethernet board.

    Since the Pokey57CNC outputs standard pulse and direction signals, you can use any stepper driver. So, you do not need to use the Postep driver to operate your stepper motors.

    The Pokey57CNC control board is extremely feature rich and can be use to control very complex light or heavy CNC systems. Since most CNC system use high current drivers, the Pokey57CNC can be used with these systems.

  • Using your NEMA 24 stepping motor with microstepping, can I get a speed range from 3 RPM to 600 RPM ?
  • I cannot find a driver for the NEMA 14 Stepping Motor (17 oz-in 1/4" dual shaft) on your site, would something like the Pololu DRV8834 be okay? (I note that the stepper requires 2.7v)
  • Can I connect a 36V power supply to 2.5 AMP Stepper Motor Driver. On the actual driver it shows 12V - 24V, but in the description and data sheet it indicates that it can accept 8V - 45V. Will I benefit from more powerful power supply. Thanks

    The 2.5 amp driver can only accept a power supply between 12 volts and 24 volts. If a 36 volt power supply is used for this driver, the main driver chip will exceed its maximum voltage rating and cause failure.

    If you need to spin your motor faster, you can either use a more appropriate driver (i.e. 3.0 amp driver) or you can change the mechanical parts so the axis has faster travel.

  • For a stepper motor that requires 5.5 amps, would you recommend setting the stepper driver to 5.43 or 6 amps? Better to go lower or higher?

    If your motor spec call for 5.5 amps, it is best to set the driver for the setting that matches that spec, or the next lowest value. This will allow the motor to run within its designed characteristics.

  • 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 HAVE NOT SEEN ANY REFERENCES TO STEPPING MOTOR ENCODER FEED-BACK FOR CLOSED LOOP CAPABILITY IN OF THE HARDWARE YOU SELL. THIS A SUPPORTED FEATURE WITH HARDWARE/SOFTWARE SELL?

    I haven't delved into using encoders with stepping motors too much. From my research, you need to have a controller that can provide the closed loop control, rather than software handling that process. I have also found from my research that using encoders on stepping motors is generally used to stop the machine in the case that the motor failed to achieve the commanded position for some reason and gives the user the chance to correct and continue with the job.

    If you want proper closed loop control, it may be best to go with servos and servo controller that provide the closed loop control within the real of those two components.

  • I have an engine NEMA 34 from Y axis on my green bull that do not response, I already check connections and everything seems to be OK, how can I check that the motor it's working properly or not?

    If one or more motor is not responding, please follow the troubleshooting directions below:

    For parallel Bob only! Make sure both the parallel and USB are connected.

    Re-check wiring, and connections for continuity (no breaks in the wires) and check for correct wiring locations from driver to BoB.
    Check dip switch settings on the driver.
    Check components, by swapping the motors (ex. y-axis motor to z or x-axis driver and z or x-axis motor to y-axis driver) to check if motor functions on another driver.
    Depending on software check step low active (mach 3) or invert pulse (planet-cnc) for the axis which is not responding.

  • 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.

    Here is a video tutorial to calculate the steps required depending on your mechanical linear motion components. (

  • I need the calculation to determine the stepper motor torque to find the load that it can lift using a lead screw at 1/2" diameter with 13 TPI.

    There are two main questions that we can answer with respect to motor torque and the mechanical advantage of lead screws, 1) What torque motor do you need to lift a particular weight, or 2) What maximum weight will my motor torque be able to lift.

    This formula uses Newtons (N) as it's final unit. Use this with the included radius (R) to determine the torque. Newtons can easily be converted to lbs or ounces using online conversions.

    Effort = Sf + (Load/(2 x pi x (R/p) x Se))

    where:
    p = pitch of the screw
    Se = screw efficiency = Standard lead screw will be between 20% (.2) and 40% (.4)
    Sf = static force. This is the force that is needed to start the movement. The number may be eliminated, but it is good to use a number in the 5 N to 20 N range.
    Load = the expected load that the effort will need to carry (i.e., the router and the included axis assembly that the motor will need to lift)
    R = radius of the lead screw


    This formula is based on the "law of the machine"

    The final effort amount with its unit of newtons and R will be the torque. For example, if the effort comes to 100 N (newtons) and the R is .5 inches, then you can assume that the effort is 50 N-in since it would take twice the effort to turn form the one inch mark from the center of the shaft.

    Example:

    Load = 90 N (20.2 lbs)
    R = 1 inch since that is the length from the center of the shaft that the motor is rated
    p = 1 inch / 13 = .08 inches

    Effort = 5 N + (90 N / (2 x 3.14 x (1 / .08) x .2))
    Effort = 5 N + (90 N / (6.28 x 12.5 x .2))
    Effort = 5 N + (90 N / (15.7))
    Effort = 5 N + (5.73 N)
    Effort = 10.7 N = 2.4 lbs = 38.4 oz-in

    I am putting the oz-in on the end because the formula considers the distance from the center of the shaft to be one inch.

    Therefore, a 425 oz-in motor would be able to lift a 20.2 lb Router with its accompanying assembly. If the assembly and router is heavier, plug in the numbers and determine the effort required.

    With a bit of algebra, the formula can be rewritten to find the load:

    Load = (Effort - Sf) x (2 x pi x (R/p) x Se)

    Another formula that does not consider friction at all:

    Effort = (Load x p) / (2 x pi x R)

    Lets see if we get similar results:

    Effort = (20 lb x .08 inches) / (2 x 3.14 x 1)
    Effort = 1.6 / 6.28 = .255 lbs = 4.08 oz-in

    The results from both formulas appear to be very small because a 13 TPI screw will have enormous mechanical advantage.

    It is evident that the first formula that does consider friction that we are loosely estimating is far more conservative than the second formula. Either way, even the most conservative formula shows that the 425 oz-in motor will handle very large weights. If you are using a lead screw with only two turns per inch, .5 inch pitch, you can determine the requirements with the first formula.

    Example for a 10 TPI 5 start (2 turns per inch) lead screw:

    Load = 90 N (20.2 lbs)
    R = 1 inch since that is the length from the center of the shaft that the motor is rated
    p = 1 inch / 2 = .5 inches

    Effort = 5 N + (90 N / (2 x 3.14 x (1 / .5) x .2))
    Effort = 5 N + (90 N / (6.28 x 2 x .2))
    Effort = 5 N + (90 N / (2.512))
    Effort = 5 N + (35.83 N)
    Effort = 40.828 N = 9.18 lbs = 146.88 oz-in
