Question #: 6821

Question: Can I power the BOB w/Relay through appropriate pins and remove USB?

Current Solution

We do not have designated pins for power on our BoB w/Relay, other than through the USB. We would not recommend removing the USB on our board since it may cause issues and irregularities within the board.

  • Can I power the Mach3 USB interface 24V with a 48V power supply?

    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.

  • Can you sell me a kit to control my motor from the pc? I already have a motor, driver and power supply.

    All you need is a CNC controller like the following options:

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

    This controller is easy to connect using standard wire screw terminals and works with the mach3 control software.

    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

    This controller is a little bit more difficult to connect, but is a more feature-rich controller and will work with both mach3 and mach4 CNC control software titles.

    Specifically, a CNC controller connects to the computer via a USB cable and connects to the motor drivers. These controllers also connect to the limit switches, spindle/router control, air/fluid/mist control, etc.

  • can I control the speed of a 2.2 spindle through your 5 axis breakout board with relay?

    Yes, you can control the speed of the 2.2 kW spindle, and the other spindles we sell, through Mach3 software. It requires making some changes to the settings in Mach3 and in your inverter. It also requires an additional part, which is called a USB to Serial Converter, found on our site here:

    https://www.buildyourcnc.com/item/Interfaces-newbiehack-Interfaces-TTL232R-USB-UART-Serial

    I have some additional instructions, that I will send upon request, by email. I will also be adding a complete tutorial and video, to the website, on how to do this soon.

  • What power supply do you recommend for the spindle and limit switches if I buy the USB Mach3 breakout board?

    Any of the following power supplies will be fine for powering the Mach3 USB controller:
    https://www.buildyourcnc.com/item/24v

    however, the limit switches do not need high current, so the following power supply is sufficient for the task of connecting limit switches:

  • I am wiring my breakout board and it has a USB port on it. Is the USB port there to supply the 5 volt power to it?

    For our parallel breakout board (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/) the schematic will show the connections going from the BB to the drivers. The parallel breakout board uses the 25 pin parallel connection to communicate from the computer to drivers, and the USB is used to power the main-board itself, supplying 5V.

  • What wire AWG can I use to connect the power supply 24v 8.3 amps

    Most of our power supplies allow for a 9 amp current draw.

    For the Neutral, Live and earth ground, wire gauge for that level of current is 14 for relatively short cable lengths. Increase the gauge for longer lengths past 25 feet.

    For the DC 24V output terminals to the drivers, 20 gauge is fine. If the power supply is connecting to only one driver, increase the wire gauge to 14.

  • Hi I want to build a cnc laser table 13'x15' cuttting area. Is this feasible. Also would the 80watt laser be enough power to cut through carpet

    Yes, it is feasible to create a machine with a cutting area of 13'x15'. Your mechanical and structural systems will need to be able to span a bit more than the 13' if that will be the axis travel along the gantry.

    We have not cut carpet with our lasers, but I don't see why not. With that said, be extremely careful with the materials in the rug. Read the MSDS (Material Safety Data Sheet) for the rug you intend to cut as some materials will emit corrosive and harmful gases and chemicals when lased.

  • Where can I find information on controlling my VFD through Mach4?

    The best way to determine how to control your VFD using Mach4 is to read the MAch4 manual found here:
    http://www.machsupport.com/wp-content/uploads/2014/05/Mach4%20Installation%20Manual.pdf

    You will find that there a a few ways to control the spindle/VFD on your CNC machine or CNC Router.
    - The first and easiest is to have your VFD's power controlled by a relay. This will allow your spindle to have on/off control through Mach4 with an output pin.
    - The second is to have a controller output a DAC voltage between 0-10 volts to control speed on the VFD/Spindle. There is a termial on the VFD to receive this signal line. The controller will also have an output that outputs a high or low and that can control the on/off on the VFD.
    - The third, and more difficult of the three methods is to use a USB to Serial adapter (USB to USART or RS-485). The Computer plugs into the adapter using a USB cable and the adapter uses the RX/TX to connect to the VFD's terminals for communication. This will provide a great amount of control. Mach4 will need a plug-in to make this option work.

    You will need 24 volt relays for the output on that board since that side of the board requires 24 volt power at the V+ and V-

    Thanks again.

    Using the Mist, spindle or flood pins...

    Buildyourcnc response:
    There is an IN, GND and 5V for the digital side to engage the relay. There is an S, O and P for the power line of the device to be controlled.

    The 5V and GND must be connected to the 5V and GND from the USB board. The IN is the wire from the output terminal (i.e. mist, flood, spindle).

    For the power side, here are the scenarios:
    - P to O connection is normally open
    - P to S connection is normally closed

    So, if you have the power wire that would plug into the wall, the L "black" wire from the power cord will pass through this part of the circuit (cutting the wire and one end in the P terminal and the other end in the O or S terminal). Generally, the P to O is used as this connection is normally open and when the relay is engaged, the circuit will close allowing the current to flow through that wire.

  • I would like to mount the CNC controller to the gantry and use the ethernet cable routed through the cable carrier, is ther ok?

    As long as the Ethernet cable is not next to stepper motor cables (between the stepper motor and the stepper motor driver) you should be fine. If you are using a spindle, make sure to shield the cable between the spindle and the VFD as well.

    Additional Information:
    One of my customers is testing this scenario. He is using CAT7 Ethernet cable which is double shielded. I/He will post the results when tested.

  • I connected 5Vdc power to the alternet connector of the USB Breakoutboard with the proper jumper setting and the board fried. What did I do wrong?

    Can you test the output of the 5V DC adapter to check the output voltage?

    Additional Information:
    The 5VDC voltage was generated by a PC ATX power supply and was measured (5.0VDC) just before connecting it to the controller PCB. I also verified polarity prior to powering up.

    Additional Information:
    Please call us to initiate a replacement of the USB interface. We would also like the existing USB interface to be return so that we can investigate the cause of this failure.
