  • I have your nema 24 motors using the 36v power supply. Should I use the Bipolar series for the wiring the motors since I am using the 36 volt ad not a 24v power supply?

    When connecting our power supply, no matter if it is 24 or 36 volts with our drivers/motors, you should always use bipolar parallel. This will allow you to have the best torque at higher speeds.

  • I have a blue brew break-out board. Do I use a seprate power supply for it and what amp output should it have if used.

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

  • 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.

  • [77] What circuit breaker should I use for this spindle?

    The 2.2kW spindle has a power rating of 2.2kW or 2200 watts.

    If the VFD AC voltage input is rated for 220 volts, then 2200 watts / 220 volts is 10 amps, so a 15 or 20 amp breaker will work.

    If the VFD AC voltage input is rated for 110 volts, then 2200 watts / 110 volts is 20 amps, so a 25 or 30 amp breaker will work.

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

    I would recommend either a 36VDC or a 48VDC power supply with 10 amps. Here are links to these power supplied on this website:

  • 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)

  • What are the dimensions of the 24v 8.3A power supply?

    The dimensions for our power supplies will be the same.

    Dimensions:

    W: 4.5" / 114.3mm
    H: 2" / 50.8mm

  • [797] Can this relay accept two separate signals?

    Yes, the purpose of the dual relay is so you have the ability to control two separate relays with two separate signals. One signal will go to one of the two relays, and the other signal will go to the other relay.

  • What power supply would be adequate for the whiteAnt 3D printer?

    The whiteAnt will work with a 6 amp 12 volt power supply. If you add more peripherals to the machine, like heating bed, you will want higher current. Each motor draws 3.0 amps at full torque. Most of the time, only the x and y axes are moving at the same time, and the drivers are only allowing a max of 2.5 amps and they should be set for about 2.0 amps so they don't overheat (they have overheat protection and the LED will light up, so you will be fine if it does overheat, but your model may suffer). The remaining current will be enough to keep the hot end heated.

  • What wiring should I use to connect two motors for one axis?

    Yes, you can use 2 motors in the same axis output, however you will still need a driver for that motor! Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

    Also you can run a slave motor using another axis on the board, and setting it up in the Planet-CNC settings.

    Planet-CNC/File/Settings/Axes, here you will enter 3 in the Number of Axes location, and then change the Function of the Axis 4 to Slave 1. There you will have the 4th axis or A-axis be a slave for the x-axis.
    Slave 1 - X-Axis
    Slave 2 - Y-Axis
    Slave 3 - A-Axis
    Slave 4 - B-Axis
    Etc...

    Here is the wiring diagram for the MAch3 USB breakout board:
    https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf

    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-

    Customer Response:
    My inquiry is for the Planet CNC USB and 5v relays.
    I am 99% finished with my 2 axis lathe build and this is the last item for me to conquer.
    I want to control power to router, and vacuum with the BOB going through the 5V relays purchased on this site.
    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.
