Adding more fans will require more power from the power supply. Each fan should have the amps that the fan draws. Add the total amps from the three fans and add one amp for the pump and you will have the total power requirement. The 12V 2amp power supply that accompanies the spindle cooling kit will probably be insufficient for the additional two fans.

[772] Can I add 3 fans and a bigger radiator to this with the 12vdc power supply

The radiator (fan and radiator are also called the heat exchanger), can be mounted using M3 screws at the back of the radiator. These are very small screws and may not be as secure as you need and I sometimes use #6 machine screws. Since the metal of the radiator is thin-gauge, it is easy to tap the holes with the #6 machine screws. I also like to use short rigid tubing, or bushings as standoffs to allow air movement.

[772] How do you mount the radiator?

This instruction assumes you are using the 24VDC power supply that is sold as an option with the kit.

Connecting the 24VDC power supply to the fan and the pump:
- Take an extension cord, cut off the female end and expose the black, white and green conductors
- Strip the ends of these conductors
- Connect the black to L, white to N, and green to the earth ground symbol on the power supply
- The V+ and V- on the power supply will connect to both the pump and the fan
- The Fan's red to V+ and black to V-.
- If the pump came with a black and gray wire, the gray wire on the large connector of the pump is the V+ and the black wire on the same connector is the V-. the wire by itself with a small connector is not connected.
- If the pump came with a red, white, and black wire, connect the red to V+ and the black to V-, like the fan. The white wire is not connected.

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

The number of watts is not available for this radiator. The fan/radiator combination will allow you to calculate the watts, depending on the RPM of the fan but there are other variables as well that makes this calculation more challenging. The fan and radiator provided, with the flow of water with the pump provided are more than enough to cool a spindle within an environment that has an ambient temperature below 90 degrees.

The radiator is aluminum. The fin density is 18 fins per inch. There are 8 tubes and the connecting process is brazing.

I'm actually not sure, but I believe it has something to do with reducing splashes. At least, that is what it seems like while watching the water flow. If others know, please add to this.

Depth of Field. This is how far the focal point goes before re-expanding again. With a 2" lens, you have approximately 2-3mm of DOF. This means that you'll have 2-3mm of perfectly focused laser before it starts to re-expand again. If you have a 4" lens, you will have up to 7mm of DOF.

Yes, that is highly recommended for all the reasons you can imagine. Say you were doing engraving, not surfacing the spoilboard will either exhibit some areas that have no engraving at all, or areas that have engraving that is too deep. If you are cutting completely through the material, then one end may be cut all the way through but the other end will not have a complete cut, or produce onion skinning on the bottom of the workpiece.

The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

IF YOU HAVE CIRCUIT (OR PICTURE) OF HOW THIS RELAY IS CONNECTED TO THE ROUTER

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.
