  • What is the benefit to using a spindle over a standard router?

    This solution will refer to the water cooled spindles that we sell. Generally, routers are air cooled which push air downwards through the router to cool the router motor. This has an undesirable effect for CNC machines that will blow the dust and chips into the air. The water cooled spindle will not blow since it uses water to cool the spindle motor. This allows the chips and dust to be confined within the dust shoe and get removed by the vacuum. Additionally, standard routers have a sound level that far exceeds that of the spindle.

  • how to conect the VFD spindle using 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.

  • Is there a recommended break in process for a 2.2kw water cooled spindle?

    A break in process, I'm guessing means if the spindle needs to be turned off for some reason? If so, then no. The water cooled spindle can be run constantly. We run our spindle for very long periods of time.

  • Can you control the spped of the 2.2 KW spindle using the breakout board and Mach3 soft ware?

    Yes, you can control the speed of the 2.2 kW spindle, and the other spindles we sell, through Mach3 software. It requires making some changes to the settings in Mach3 and in your inverter. It also requires an additional part, which is called a USB to Serial Converter, found on our site here:

  • Can you tell me what gauge wire is needed for limits switches and the spindle?

    The hookup wires you will need is 22 to 24 AWG stranded and shielded for the wiring of the limit switches and E_Stop. Our kit customers select various places for these switches, so we don't supply the wiring. If you don't use shielded cable, you will need to change the debounce setting in Mach3 (if that is the control program you are using).

    We typically use 14 AWG stranded wire for the VFD to Spindle (U, V, W) connections.

  • Will any of you boards support running dual spindles and using clearpath servos

    Our Pokeys57CNC CNC Controller will control the Clearpath servos. Clearpath servos can work using standard step pulses and direction signals just like stepper motor drivers, so you can use a wide variety of controllers.

    The Pokeys47CNC has multiple relays on-board, but only one PWM for speed adjustment. If speed adjustment is not important, then you can use this board for more than one spindle. You can also use the Modbus connections (RS-485) in your VFD to control speed and other functions as a way to control multiple spindles.

  • on the 2.2Kw water cooled spindle, what is the cooling port thread type and size?

    It is an M8 metric size on the port going into the spindle, and a 1/4" compression on the other side.

    Is the M8 port a M8x1.25 or M8x1?

    If you are referring to the book build, use a chamfer bit that is large enough to create a chamfer for most of the edge of the 3/4" thickness of the board, but still has a sliver of space for the bearing on which to ride.

    Additional Information:
    Mine is M8x1mm. I replaced the stock fitting with a brass hose barb and used "steel wire reinforced vacuum hose" with a 1/4" ID because it resists kinking and collapsing.

  • Okay guys, what fluid are you using for the spindle to keep them cool? do you recommand anything else beside water for the spindle?

    We have always used water for our cooling, but since this is a heat transfer condition, you should be fine with any form of coolant.

    Additional Information:
    We live in a cool part of the USA. My CNC is in an unheated garage and temperature gets to -10 degrees Fahrenheit. So we use 100% anti-freeze that is used for winterizing campers. Use same coolant year round. Put 3 gallons in a bucket with fish-tank pump, and it works great. Since there is 3-gallons of coolant, no need for fans to cool the coolant. Just pump from tank to spindle back to tank. And no worry about frozen coolant.

  • Having issues with my cnc router constructed with your materials.

    Please be very specific on what issue you are having.

    Is this the scratch build machine? It is a machine kit that you purchased from us?


    Having issues with my cnc router constructed with your materials.
    1.) Machine is calibrated with a precision six foot steel scale at 30” measurement and appears to be right on the dimension under no load condition.

    2.) When cutting a test program of a rectangle Y 12” x X 6” the final cut dimensions are:
    X = 5.946 (-.054) short and Y = 11.900 (-.100) short.
    This is a chain drive machine using your small chain stock.
    Can chain tension be part of the issue or am I missing something????
    Have made several cuts with reduced feed and depth of cuts. No change in errors……
    Best regards.
    Marc

    This is a machine of my own design that I built using your electronics package purchased in 2010. Including your five start Z axis lead screw and your small chain with spur gears package for the x and y axis. this machine is designed to fit that floor space of my shop. Last year I sent you folks a photo of the unit. It has hardened steel X,Y and Z rails not the aluminum rails that you offer. it is also made from Baltic Burch 3/4" plywood.

    When cutting a test program of a rectangle Y 12” x X 6” the final cut dimensions are:
    X = 5.946 (-.054) short and Y = 11.900 (-.100) short

    There is a dimensional discrepancy from programmed dimension and the actual cut dimension???? what could cause this issue????
    please refer to data supplied........... thanks.
