Question #: 13975

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

Current Solution

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 functionality is lost if 24V power supply not provided to "Mach3 USB Motion Card"?

    If the Mach3 USB does not have a 24V power on the limit switch/output/DAC side of the board, then those functions (limit switches, outputs and the DAC) will not work. If you have a spindle, you can use the 24V output from the VFD (Variable Frequency Drive) to serve as the 24V supply.

  • DO NEED LIMIT SWITCHES, IF SO WHAT IS YOUR RECOMMENDATION?

    Limit switches are not really needed for this level of a machine, but if you do want to use them, then you will need to connect them with shielded cable and ground the shield at both ends and any other non-used wire in the cable. Limit switches are very susceptible to the motor interference. You will also need to adjust the debounce in the software you will use.

  • Good evening, if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors. I have a 48V 12amp power supply. Thank you

    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.

  • WE'RE GLAD THAT CDC HAS MADE A UNIVERSAL INFLUENZA VACCINATION RECOMMENDATION TO VACCINATE EVERYONE 6 MONTHS AND OLDER. WOULD YOU TELL US HOW THIS CAME ABOUT?

    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.

  • What relay should be used with your USB BOB for controlling mist/flood/spindle on/off?

    The relay that should be used with your USB BOB for controlling mist/flood/spindle on/off is one of the following options.

    You could get and use the Planet-CNC.com Output Board found here, http://www.planet-cnc.com/index.php?page=shop

    Or you could create your own setup using a resistor, solid state relay, transistor, and diode. You can watch this video, https://www.youtube.com/watch?feature=player_embedded&v=PJO_XoLL6lQ, to find out the correct way to accomplish this.

    Any of the following power supplies will be fine for powering the Mach3 USB controller:

  • I trying to setup your USB Controller card. The planetcnc does not load the card, no driver for usb card. Using windows 8.1.

    To install the USB breakout board, there will be no driver to install nor any pop-up will be viewed in your windows task-bar, except only to notify that a USB device has been connected.

    If you have planet-cnc installed it should automatically ask for a license number, which if you don't have you will continue without entering any numbers. Please read carefully since there is a pop-up that can erase the entire firmware on your board, and you will basically have a dead board.

    Please email customerservice@buildyourcnc.com for further assitance.

    Additional Information:
    For Windows 8.1 you need to follow special driver installation steps. Download Planet-cnc software MANUAL and scroll down to that paragraph (without it you will not be able to install and use your board).

  • I would like to make a handheld remote for the USB CNC Board using a joystick instead of momentary switches. Could you suggest one that will work with your board.

    The USB interface only works with momentary switches unfortunately. If you have extensive knowledge of digital electronics, you can apply a receiver that uses a microcontroller and a transmitter with another microcontroller that produces the pulsing signal with the controls that you need.
