Question #: 14064

Question: Will the 1/2"5 start and 3/8" 5 start work in unison even though the turns per inch is different

Current Solution

If the turns per inch on a lead screw is different, then the nut on the lead screw will move at a different velocity.

Additional Information:
Let me explain in more detail.

Let's say you have two lead screws:

- 1/2" 5 starts at 10 TPI = 2 turns per inch. (5 starts / 10 TPI = 1/2 inches per turn or 10 TPI / 5 Starts = 2 turns per inch.)

- 3/8" 2 starts at 10 TPI = 5 turns per inch. (2 starts / 10 TPI = 1/5 inches per turn or 10 TPI / 2 starts = 5 turns per inch.)


So, if two stepper motors (one connected to the 1/2" lead screw and the other connected to the 3/8" lead screw) turned 10 revolutions in 2 seconds, the 1/2" lead nut would travel 5 inches and the 3/8" lead nut would travel 2 inches at the 2 second mark.

  • How do I order the 10 TPI 5-start 2-turns-per-inch screws?, just shows $ per inch with no option for lenght.

    When purchasing the 1/2" 5 start lead screw, the length is based on the quantity. Specify the total length you will need and we will email you (if you don't contact us first) to determine the cut lengths.

    For example, if you desire 36 inches of lead screw for the X axis and 12 inches of lead screw for the Y axis, just purchase 48 inches of lead screw and tell us you need this lead screw cut so you have two lengths at 36 inches and 12 inches.

  • 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.

  • the relay on the 57CNC card turns on and the VFD starts up but it won"t turn off. Relay #1 stays on all the time. Even the Estop won't turn it off. Relay #2 doesn't work all

    Turns out it was an electrical noise problem from the VFD. Troubleshooting showed me everything worked perfect even with the drive powered up but when the VFD started it would NOT stop from Mach3. I had run shielded cable and grounded it in the VFD but I had an intermediate break in the shield wire at my Master Control Relay (MCR) that is activated by an Estop on my control panel.

    This confirms the importance of shielded cable and making sure that the shield is contiguous.

    My guess is the wire(s) going to the dry contacts on the relay carried enough energy to fire the base of the transistor supplying coil voltage to relay #1. Or there might have just been enough induced voltage to the relay to fire the relay coil.
    I've fought similar VFD noise issues for 25 years and it still amazes me how pesky it can be. It's impossible to maintain any separation of signal and motor leads in the tiny space in the VFD.

    Additional Information:
    As in, wire all 8 in pairs? Also, what would you suggest for lubrication on the rails?

    Additional Information:
    Yes, the color/color would be two separate wires going to a single terminal on the driver.

    The lubrication question would be great as a new question on the CSL.

    Also, the above link to the pdf isn't parsing correctly. The link to the pdf datasheet is in the description in the first link (link to the stepper motor).

  • I AM USING A XYLOTEX 3 AXIS BOARD AND WANT TO ADD ANOTHER MOTOR SLAVED THE X-AXIS. WILL DRIVE CW230 WORK?

    If the pins from the terminal block on the side of the board are outputs, or at least 2 of them are outputs, then you can connect our modular driver to the board (example: cw230). If they are all inputs, then you would not be able to connect an external driver.

  • Will your 2.5 KW spindle work with my Hitachi WJ200-022SF VFD and does it have a thermal couple temp output?

    From reading on the Hitachi WJ200-022SF VFD, it seems as it will work just fine with this VFD. However since we have not tried this cross match, I would carefully take each connection and setting into great consideration and detail on both the Hitachi recommendations for setup, as well as our spindles recommended setup.
    Our spindles do not have a thermal couple temperature output.

  • What are the toggle switch settings on the stepper motor drivers for the .5 in. lead screw 10 tpi 2 turns per inch? Thankyou!

    On the top of the stepper motor drivers is a grid with the appropriate toggle switch positions for the lead screw being used. If it is 2 turns per inch, the proper toggle switch positions would be 01101110. Try this and see if it works.

  • What is the cp- and cw- on the 2.5 Stepper motor driver modular unit. my motor will not run. i believe this is my wireing issue

    Black to A+
    Green to A-
    Red to B+
    Blue to B-

    (X-axis 2-CP-,3-CW-)
    For our USB breakout board (https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/):
    (x-axis CP-,CW- to ground)

    Additional Information:
    I have USB breakout board connected as: CW-> 5V, CP -> CP, and GRD to GRD/COMM next to 12-24V Pin.
    The motor works perfectly in one direction.
    Will not jog in the other Direction.
    I still do not know what is CP- and CW- as it is not labeled on the board, unlike your other motor controllers.
    Can you submit a wiring diagram for the 2.5 AMP controller

  • Does the spindle accept different collet sizes, or do I need to purchase different spindles that will accept different collets?

    The 2.2kW spindle will accept up to 9/16" (a little over 1/2") end mill shanks down to very small diameters (any size that ER-20 will accept). The 1.5kW spindle has a reduced collet size and will only accept up to 5/16". The 1.5kW will accept ER-11 collets.

  • I'm looking for a CNC which will mill 4x8 MDF/OSB and birch, as well as other 3/4" species. Previously I used a Shopbot and Partworks - can we expect the same performance from this?

    The greenBull 4x8 is designed specifically for heavy usage with a larger gantry and 3 large NEMA 34 651oz-in motors on each axis. You can expect superior performance from the greenBull since it is specifically designed for every day production of 4x8 sheets of material.

    Additional Information:


    Additional Information:
    The greenBull response was not an answer to my question. I'd still like to hear from users. There must be some suggestions comments from those that have built the machine?

    Additional Information:
    Strange that you got the response matching the greenBull answer. That was probably our automated "closest match". I would re-state the question and select the "no, the answer is not related" and let it hang out on the customer service page for a while to see if you get any bites.
