  • how do I connect my spindle to mach3 so mach3 can control it

    It is not necessary to connect the spindle VFD (Variable Frequency Drive also called an Inverter) to the computer or CNC motion electronics. The VFD can be controlled independently using the control panel on the VFD. The control panel has the ability to control all aspects of the spindle including Speed, Torque, limits, etc. However, you can connect the VFD to the computer so the CNC control program can control the spindle during the CNC Machine operation. You will need to connect the VFD to the computer via a serial conection (in this case, it is the RS-485 protocol).

    The following are instructions on how to connect the VFD to Mach3 via this RS-485 serial connection.

    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.

  • How can I make LinuxCNC control a spindle?

    LinuxCNC has excellent documents; however, I would like to offer our help in case you don't understand the information on that page. So, please use this FAQ (Question #: 13233) to state your questions by submitting additional information below.

    The LinuxCNC spindle control page is found here: http://linuxcnc.org/docs/html/examples/spindle.html

    Additional Information:
    After reading the LinuxCNC page my first questions would be can the spindle be controlled by PWM signal? Also, what pin on the parallel port would I set to Spindle Enable and FRW?

    Additional Information:
    To connect your computer to the VFD, use a USB to RS-485 interface. RS-485 is just a serial interface protocol that uses standard 0 to +5 voltage TTL signal levels for communication (as opposed to RS-232 which uses -12v and +12 for signal level changes).

    Get a high quality interface to reduce any issues during the process. The VFD should have two terminals labeled RS+ and RS-. The USB to RS-485 adapter should have this labeled on it as well so the connections should be relatively straight forward.

    In the VFD parameters:
    PD001: 2 to accept RS485 commands
    PD002: 2 to accept frequency comands
    PD163: 1 to RS485 slave address:1
    PD164: 1 RS485 baud rate 9600
    PD165: 3 8bit, no parity, 1 stop bit

    Make sure LinuxCNC is also set accordingly:

    The PIN14 and PIN16 in the stepconf wizard should be set to unused because you don't want LinuxCNC to be outputting unnecessary signals.

    In the options step of the stepconf wizard:
    - Check the Include Halui user interface component.
    - Check the Include custom PyVCP GUI panel.
    - Check Spindle speed display

    You will want to edit the custom.hal text file located in the folder that was created from the stepconf wizard. Add these following lines:
    loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
    net spindle-cmd-rpm-abs => vfd.speed-command
    net spindle-cw motion.spindle-forward => vfd.spindle-forward
    net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse
    net on motion.spindle-on => vfd.spindle-on

    The dev folder in linux is typically used for interfacing devices and peripherals to the computer as these devices are communicated by simple memory addresses and these files are linked directly to these addresses.

    Under the custom_postgui.hal file, change this line:

    from: sets spindle-at-speed true
    to: net spindle-at-speed => cfd.spindle_at_speed

    and add the line:

    setp vfd.enable 1

    When you start LinuxCNC, you will a spindle section with the reverse and forward buttons, a stop button and - and + buttons. Use these buttons to conform that the spindle is functioning properly. The spindle speed indicator in LinuxCNC will show the spindle speed and you can confirm that this is equal to the speed indicated on the VFD.

  • I cannot turn the shaft of my stepper motor. It not even connected to a driver

    The motor is creating it's own EMF when you try to turn the shaft manually. When coils are connected (or not connected) to any circuit that is not powered can cause unpredictable results.

    The motor freezing from just turning it by hand with no connection is surely the wires touching each other. This is actually how we test if a motor is good or bad. If the motor freezes when two of the wires are touching, that means the motor is functioning properly since the magnets are causing current to flow through that coil opposing the magnet.

  • The spindle drops on our greenBull when power is turned off. How do we stop this?

    When you say the spindle drops, are you referring to the z-axis assembly that contains the spindle? If so, did you replace the lead screw and anti-backlash nut with a ball screw? Ball screws have extremely little friction and will cause an assembly under gravity to move down. If not, your lead screw and anti-backlash nut friction is extremely small, which is surprising and I have never seen this before. I would be interested in seeing a picture of the assembly. Please send a picture to techsupport@buildyourcnc.com so I can investigate this issue further.

    Additional Information:
    We haven't replaced or disassembled anything on the z-axis. I will try to get some photos sent to you. Are there any adjustments or recommendations for PM of the z-axis assembly?

  • Transaction EQEPB4915043, My 2.2Kw Spindle and Inverter showed up without any manual or instructions. Can you provide a manual? Thank you

    The spindle does not come with a manual, however the inverter should come with a manual booklet in the box. The wiring diagram and PD settings for the inverter and spindle (https://www.buildyourcnc.com/item/spindle-inverter-2!2kw-spindle-novfd) can be view together on the spindle page, also you can use a local hardware store extension cord (orange) to connect/wire from your outlet(220V) to your inverter and spindle accordingly from the diagram.

    Additional Information:
    I also received a spindle and inverter without a manual. While the diagrams on the product page were sufficient to get the unit running, there is no documentation anywhere to be found concerning the terminal block that is used for external control. What does one have to do to get a hold of the manual that was supposed to come with the inverter? Manuals for the 220VAC model are plentiful online; however, manuals for the 110VAC model are non-existent.
