  • I am looking for a lead screw with a 4mm lead, at least 4 starts and 36" in length, can you help me out?
  • 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.

  • Just getting started with building the "Book Machine". I'm looking for feedback from users. Lessons learned, performance etc.

    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.

  • If I buy the 1/2" 5 start lead screw and the 3/8" 5 start lead screws will it all work together

    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.

  • should all three lead screws be a 5 start?

    The precision and number of starts for a lead screw will depend on the application. Having an ACME lead screw with 5 starts is a good balance for many applications so the machine will travel quickly along the axes with motors that hold best torque at low RPM. All three axes would benefit from 5 start lead screw for general applications.

  • I am looking for a schematic to wire a C10 BoB to a KL430 driver.

    CP+ to COM
    CP- to STEP
    CP+ to CW+ (small jumper wire)
    CW- to DIR

    Additional Information:
    If the driver does not have CP or CW labels, the CP is Step and the CW is Direction or DIR. If you connect the 5v to CP+ (or Step+) and CW+ (or DIR+) and the pin to CP- (or Step-) and another pin to CW- (or DIR-), then in software, the configuration for the step on that axis must be active low. Otherwise, if you connect the GND to CP- (or Step-) and CW- (or DIR-) and the pin to CP+ (or Step+) and another pin to CW+ (or DIR+), then in software, the configuration for the step on that axis must be active high.

    Additional Information:
    If you have a driver that is labeled pul, dir and ena: Pul+ is the Step+ and Pul- is the Step-. Pul is short for pulse. A pulse will create a step. Don't worry about the enable terminals.

    On the x-axis, pin #2 can go to pul- and pin #3 can go to dir-. The 5v will go to pul+ and dir+. The configuration for each axis for step will be active low and toggle active low for the dir on each axis to make it go in the direction desired.

  • Do you offer custom sized machines? I am looking for a 5'x5' version.

    Most of our CNC machines have the ability to be customized by length. The greenBull 5X for instance comes standard at 5' x 10' but it is really only the gantry width that is fixed. The length can be easily altered. If you are interested in receiving a custom quote, you can email sales@buildyourcnc.com.

  • I would like some longer HIWIN rails and ballscrews for my x-axis, 9 feet or 108 inches. You list maximums as 78 inches.

    Yes, however, if you are needing a length of the HIWIN specification rail longer than our 78" max length, then you can abut more than one rail together to increase the length of the rail. We do this for our long X-Axis travels on our Fabricator pro machine.

  • looking for wiring schematic for redleaf electronics to huijang yl600 VFD 110v, 2.2k, thanks!

    It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol.

    The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

    You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

    Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

    You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
    - PD001 - value 2 - Enables with communication aspect of the VFD
    - PD002 - value 2 - Enables frequency control from the communcations port
    - PD163 - value 1 - VFD address
    - PD164 - value 1 - Baud rate of 9600 (speed of the communication)
    - PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

    Copy the dll file to the PlugIns folder of mach3.

    Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

    Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

    No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

    Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

    You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.

    Will this work with the brand called "best "vfd as well.

  • I am looking for a 4'x4'x8" cnc machine kit... do you carry something like this?

    Yes, our greenBull is the best machine to exhibit those dimensions. The 8" z-axis travel can be achieved by making sure that the table and bed of the machine will built with a depression that lowers the work are to the desired travel and clearance depth.
