A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

What would be your recommendation for "power supply 2 (24vdc)" connecting to USB motion card?

We generally use the USB to power the interface (breakout board). The current from the computer is sufficient to supply the breakout board.

Breakout Board with Relay. What is the USB connection on this board for? Does this board Still require a 5v power supply?

I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

USB connection can not move the gantry, it is connected but noticed in device manager is missing drivers. PCI serial port... any help would be great also there is two mach3 profiles one showers numbers moving as like the gantry should be but is not.

The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

Additional Information:
I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

Additional Information:
Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

I bought a 'BuildyourCNC V1' relay board to go with my mach3 usb controller. I have been sent a 'Songle' relay. It's not the one in your picture and it's got different connections, for which there isn't a wiring diagram. The one I ordered says it is 5v, this one seems to be saying it's a 24v unit. Can you please explain what has happened? Thanks

The relay is only used for devices like routers, spindles, coolant, mist, etc. The relay works like an automatic switch and will allow current to pass when the relay is engaged.

The firmware update for the USB board is done by PlanetCNC. with your board hooked up to the computer via USB cable, log into PlanetCNC. Then, from the Machine tab on the toolbar choose firmware from the drop down and click on update.

All of our CNC machines can carve at that depth without a problem and do 3d carving. Our typical application is cutting sheet materials, but a good percentage of our customers cut 3D bas reliefs or even more complex 3D objects using reference points and jigs.

Most of our CNC machines have a Z travel of at least 6 inches for the smaller machines and 7 to 10 inches for our larger machines. The Fabricator Pro has a Z travel of 10 inches.

Depending on your application, you will need to consider the length of the end mill (more than the deepest depth of the 3D carving) and the stock that you will be using. If the stock plus the length of the end mill exceed the clearance with the Z axis raised to the top extent, then you will need to consider the way the table/bed of the machine is formed (maybe with a depression to take advantage of the greater need for clearance).

The greenBull has the capability of Z axis travel of up to 36 inches, but I would recommend, if milling wood, that the Z-axis not extend more than 12 inches to reduce deflection.

Make sure that the port setting for that output is set to port 3. To do this in Mach3, click config -> Ports & Pins -> click the outputs tab and in the list of outputs, select the output you want to use and set the port to 3.

You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.

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.

What gauge wire between the VFD and the 2.2K spindle? The spindle connection posts are very tiny, equivalent to 18 gauge, but that seems too small. What do you use?

There is no specific manner in connecting the water lines to the spindle. No specific output and input locations, only the diameter which we use is 1/4 Inside Diameter and 3/8 Outside Diameter (you might find another one that works just as well).
Unscrew the 2 hose nuts and feed the tube through (will be snug), and adjust the tube on the hose fittings and screw the hose nuts down. Feed the tubes through your machine towards the water bucket, making sure it will not get caught on any moving parts and cause a jam/leak, and fit one tube to the outlet of your water pump and leave the other tube to the bucket as a return line. (unless you are using a cooler like a radiator, then feed it to the outlet of the radiator and to your water pump)

Prior to the 2010-11 vaccination season, only children ages 6 months through 18 years and adults age 50 years and older were universally recommended for vaccination; recommendations for adults ages 19 through 49 years were targeted to people with specific risk factors, although other adults could be vaccinated if they wanted protection. Collectively, these targeted risk groups made up 85% of the U.S. population. During the 2009 H1N1 outbreak, additional risk groups were identified, such as obese individuals. The recommendation made by ACIP in February 2010 for universal vaccination simplifies previous recommendations, making it easier for healthcare providers to determine whom to vaccinate. The universal recommendation also makes it easier for patients to remember to get vaccinated every year.
