looking for 5 start lead screw 3/8 4 feet long i need 2 of them

If the turns per inch on a lead screw is different, then the nut on the lead screw will move at a different velocity.

Additional Information:
Let me explain in more detail.

Let's say you have two lead screws:

- 1/2" 5 starts at 10 TPI = 2 turns per inch. (5 starts / 10 TPI = 1/2 inches per turn or 10 TPI / 5 Starts = 2 turns per inch.)

- 3/8" 2 starts at 10 TPI = 5 turns per inch. (2 starts / 10 TPI = 1/5 inches per turn or 10 TPI / 2 starts = 5 turns per inch.)


So, if two stepper motors (one connected to the 1/2" lead screw and the other connected to the 3/8" lead screw) turned 10 revolutions in 2 seconds, the 1/2" lead nut would travel 5 inches and the 3/8" lead nut would travel 2 inches at the 2 second mark.

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.

Will this work with the brand called "best "vfd as well.

Stepper motors are designed to move in specific increments; these increments are called "steps". For example, a common standard is for 200 steps per full revolution. Microstepping is a method to send signals to the motor to move only a fraction of a full step at a time. For example, if a motor has 200 steps per revolution and is microstepped 1/16, then effectively there are 3200 small step movements (microsteps) per revolution instead of 200 larger ones. This makes the motion of the motor much smoother and more precisely controllable, at the cost of decreased holding torque.

Here are is a good references for stepper motor theory: http://users.ece.utexas.edu/~valvano/Datasheets/StepperMicrostep.pdf

And Wikipedia has a good overview as well:

The length of time it will take to build a CNC machine kit is not an easy answer. There may be a wide array of circumstances that limit a persons abilities to build the cnc machine kit in an efficient timeframe; however, if you have moderate dexterity and moderately mechanically inclined, you should have no problem building one of our machines within one weekend if the project has very little downtime.

Ideally, the spindle VFD should use an actual 220V socket that contains the minimum amp fuse that will allow the appropriate draw for all of the items that will be plugged into that socket. If you elect to use a boost converter, the 2.2kW spindle VFD will need a 2200 watts or more.

My brother is using 1000W and told me his spindle is working just fine. Is it safe to use 1000W ?

I still can't recommend using a 1000W converter.
