This controller does not have an encoder input to determine the speed of a lathe spindle. The Pokeys57CNC does have an available encoder input.

You have the ability to designate the 4th axis, commonly known as the A-axis, for rotary indexing operations when using a Mach3 USB controller.

To achieve this in Mach3, you'll need to:

Open the Mach3 software.
Navigate to "Config" and then to "Ports and Pins."
Go to the "Motor Outputs" tab.
Enable the A-axis and assign the respective Step and Direction pins.
Save your settings and exit the "Ports and Pins" dialog.
To calibrate the A-axis, go to "Settings" and use the "Set Steps Per Unit" option.

HOW MUCH SILICONE TUBE DO I NEED FOR A GREEN LEAN TO CONNECT THE SPINDLE

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.

I am not sure of the resolution for the PWM output for spindle speed control. However, if you are worried about getting the exact speed you need, 8-bit will provide 256 levels of increments. This translates roughly to a change of 94 RPM from one increment to another. Remember to provide some inductance and shielding to the signal lines so you won't get fluctuations in speed.

The Mach3 USB controller will work with M3/M4/M5 or M7/M8/M9 combinations. M10/M11 is not available with the controller.

The Mach3 USB controller is specifically engineered to integrate seamlessly with Mach3's CNC control software. Easel, on the other hand, offers an all-in-one CAD/CAM solution along with machine control capabilities. While Easel can output standard G-code compatible with industry-standard post-processors, it can serve as a design tool when used in conjunction with Mach3 but not as the machine control software.

[575] Will the Mach3 USB interface board support other software such as Easel?

The Mach3 USB controller does not provide 5V output signals. The Inputs, Outputs, and PWM Spindle Speed terminals are separated from the 5V side of the board. The output terminals use the 24V portion of the controller and you will need a 24V power supply to make these outputs work.

Please watch the video below to completely understand how the outputs of this controller work. Make sure that you are using the RNRmotion.dll plugin and that the port for each of the outputs is set to port 3.

[575] I cant get a 5v signal on any of the Outputs on the board. what Port# and Pin #s should I be using on Mach3?

Yes, you can use a conductive metal to serve as a zeroing block for the Z axis. All you need to do is connect the block (conductive metal) to one of the 4 inputs on the controller. The end mill must be connected to the DCM terminal (the GND of the 24V power supply) of the controller. In the inputs dialog box (config-ports and pins-inputs). Under the probe line, enter port 3 and the pin used for the block.

HOW DO I CONNECT A TOUCH PLATE TO THE BREAKOUT BOARD?

I do not recommend using the Mach3 USB controller to be used with a torch height controller. There are only 4 inputs on the Mach3 USB controller. We have tried to interface a Proma THC to this board without success; however, we did not exhaust all possibilities.

I would recommend the Pokeys57CNC controller to connect the Proma THC as I have interfaced these two before and they work well together.

The Mach3 USB will not work with Mach4. Consider the Pokeys57CNC controller instead. The Pokeys57CNC controller will work with Mach3 or Mach4 and contains more features than most CNC machines need, including 8 motor outputs, 4 onboard relays, limit home and probe inputs, galvanically isolated outputs, and much more.

[575] Will this work with Mach4. I,m thinking to upgrade from Mach3.

The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

Currently we use 20AWG 4 conductor.

HOW TO CONTROL MY 2.2 KW SPINDLE VIA MACH3

Yes, this CNC controller can be used with closed-loop stepper drivers and motors. The loop for control and feedback is between the driver and the motor. The closed-loop driver receives step and direction signals, which this controller will output which furnishes the driver with the necessary signals to move the motor. Additionally, the closed-loop driver can output a fault signal to this controller through the controller's input terminals in case the motor should encounter a situation that prevents the motor from moving so the CNC can shut down.
