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.

How do I connect the outputs on the USB motion card for Mach3?

You will need a 24V DC Solid State Relay to accompany the Mach3 USB Motion Card as the outputs on that motion card requires a 24V Power Supply.

Until we start supplying this relay, you can find these relays here:

What Relay do I need for the Mach3 usb motion card?

The Mach3 USB interface card uses 5V (powered from the computer's USB) and a 24v to power the inputs, outputs and spindle control

the mach3 usb interface can be found here:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

But the mach3 usb does not absolutely need the 24V supply. The 24v supply is only needed if you will be using limit switches (I1-4), VFD controlled automatically and for use with the outputs (O1-4)


Additional Information:
The 36v 8.8 amp power supply we typically recommend is for powering the stepper motor drivers.

What problems are you experiencing?

Additional Information:
Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

There is a 5 step process on that page to install the plug-in and the configuration xml file that is necessary for the proper functioning of the controller.

The videos on that page also demonstrate in detail how to install the software, plug-ins, xml file and wiring and testing most of the features of the Mach3 USB interface.

Hope this helps.

Is the USB hub ready for use with Mach3 at this time, or just Planet CNC?

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.

[807] What size power supply do I need to this?

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.
