  • I have two nema 34 motors on my gantry and ordered a hex inverter, now I need to wire it correctly. What type of wiring hardware do I need and I will need a wiring diagram also. Please help.

    Have you considered reversing the A and B coils on one of the motors to the drivers? This will cause the motor to spin in the opposite direction. This is the easiest method. Using the HEX inverter is a more complex method and not recommended for simple driving tasks.

  • How do I wire to nema 23 motors parallel

    Wiring two motors in parallel is pretty easy.

    Here are the steps:
    - You need to have two stepper motors and two stepper motor drivers.
    - Each stepper motor will be connected to its own stepper motor driver.
    - Both stepper motor drivers are connected to the same CP and CW pins on the interface so the same signal is delivered to both drivers.

  • Need wiring diagram from mach3 USB breakout board to inverter.

    I suppose you are trying to determine how to connect the VFD tothe relay on the breakout board. This is possible, however, not recommended as there is a more robust way to connect the VFD to mach3 or mach4 that allows that CNC machine control software to control the speed and other features of the VFD.

    Follow the instructions from this question (number 13383):
    https://buildyourcnc.com/FAQ/13383

    To get to this answer, you can also ask this customer service "How can I connect my spindle's VFD to mach3?"

    Additional Information:
    If you still want to connect the VFD through the relay, I will clarify this instruction on this question tomorrow as I don't have the information in front of me at this moment. Thanks.

  • need wiring diagram from rs485/breakout to VFD 110 v serial modbus

    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.

  • Can i wire my drivers and motors in parallel to your laser controll system to add a laser unit on my router?

    It is possible to add the laser control system to an existing CNC router but there are a few considerations:

    All of the signal wires from the laser controller that connect to the drivers drivers and all of the signal wires from the CNC controller that go to the drivers will need to first pass through a tri-state gate buffer chip that will allow one set of signal wires to be switched off and the other set switched on.

    We have a board that does this in development, but If you wish to accomplish this on your own, you will need:

    - 3 Quad buffer line drivers (each one can receive 4 signal wires): https://newbiehack.com/categories/newbiehack-integrated_circuits-buffer-quad-buffer-line-driver-throughhole
    - Some perf board, solder and a soldering iron, and some hookup wire.

    If this doesn't scare you, please feel free to submit additional information and let me know if you would like more information.


    Additional Information:
    You will also need a physical switch to select laser control or CNC control.

  • What wiring should I use to connect two 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

  • WIRING THE BLACKTOOTH LED PANEL TO PARALLEL BOB

    The blackTooth build instructions explain how to hook the four LED control panel to the USB breakout but not the Parallel BOB. Turns out it's very easy. Simply wire the corresponding LED cathodes (top pins on the display) to the matching CP- for the X, Y, and Z axises and wire the anodes (bottom pins) to the 5V terminals. For the on/off LED, wire the cathode to the G terminal on the laser power supply and the anode to the 5V laser supply terminal. Also, remove the 5V wire running from the Parallel BOB to the 5V terminal on the laser power supply. It is not needed and will cause the laser on/off light to always be on if the USB cable is connected.

  • is everything included in the 4axis cnc kit to build a cnc control box like wires,connectors,wiring diagrams ect?

    The electronics combos come with stepping motor drivers, stepping motors, breakout board (interface between the computer and the drivers) and power supply. The electronic combos do not include the cable and wires since the mounting configuration can differ from application to application.

    The wiring diagrams are located on the product page for each product. For instance, to determine the wiring for the motors, go to the specific motor that you purchase and the datasheet will be available which will include the wiring configuration. The breakout board product page will contain the wiring diagram for the remaining electronics. You can also use the electronics videos found here (https://buildyourcnc.com/CNCElectronicsandWiring.aspx) to understand the best process to connect all of the electronics.

  • On the blacktooth machine wiring diagram for parallel breakout a wire goes from 6 on the BOB to TL on the laser power supply. My power supply has an"H" followed by a "L". Which is correct? I've connected to the "L" but the laser appears always on.

    The digital signal portion of the CO2 laser tube power supply has various terminals for signal power, signal gnd, laser intensity and engaging the laser (turning it on or off). The TL and TH are triggers to turn the laser power on or off. These may be labeled L or H on some laser power supplies. You can use either TL/L, or TH/H to control the laser.

    If you use the TL or L terminal to control the laser:
    If a low signal (gnd) is present at that terminal, the laser will turn on. If a high signal (5v) is present, the laser will turn off.

    If you use the TH or H terminal to control the laser:
    If a high signal (5v) is present at that terminal, the laser will turn on. If a low signal (gnd) is present, the laser will turn off.

    You should first test the control signal from the interface with a multimeter to make sure the laser will be controlled correctly before powering the laser power supply

  • looking at woodsmith CNC and wanted better understand how it is wired. is it possible to get better wiring diagrams or manuals?

    There is a wiring diagram in the instructions on the following page:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    In the instructions, you will find the wiring diagram and further instructions below that with greater detail on how to connect the various features of the Mach3 USB controller that is used in the Woodsmith article.

    Note in the wiring diagram that COM- is the DCM terminal and COM+ is the 24V terminal.

    Additional Information:
    I built one of those and complained to Woodsmith about the wiring diagram. They said the vendor changed boards after the article went to press. Don't trust anything in their diagram. They even got the power supply wired wrong. I had to view the instructions from buildyourcnc to get things working. You will fry you drivers if you do anything that is referenced in the woodsmith article. While I did get it built and working, I had to make modifications on many of the dimensions to get it put together right. They make no mention of the tight tolerances required or how square and level everything must be. The beast works but the publication leaves you dangling when it comes to the important details after you get it built.
