Question #: 12222

Question: What wire gauge should be used for the 36V 8.8 amp power supply

Current Solution

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.

  • 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 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.

  • The electronics for my current cnc machine has a 36v 8.8 amp power supply. Is this power supply sufficient to power my new Mach3 USB interface?

    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.

  • 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.

  • WHAT LENGTH OF MOTOR CABLE SHOULD BE USED WTIH THE BLUECHICK V4.2

    The recommended total length of motor cable should be 15 feet for the blueChick v4.2

    Z - 6 feet
    Y - 5 feet
    X- 4 feet

    20 AWG 4 conductor

    If your drivers will be positioned farther from the machine, you may need longer cable.

  • What kind of wire should I use between the invertor and the spindle?

    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 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:

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

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

    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.

  • Can you tell me what gauge wire is needed for limits switches and the spindle?

    The hookup wires you will need is 22 to 24 AWG stranded and shielded for the wiring of the limit switches and E_Stop. Our kit customers select various places for these switches, so we don't supply the wiring. If you don't use shielded cable, you will need to change the debounce setting in Mach3 (if that is the control program you are using).

    We typically use 14 AWG stranded wire for the VFD to Spindle (U, V, W) connections.

  • What warranty is there on the 40W laser and power supply?

    Most of our products have a warranty that extends for 1 year; however, there are parts like end mills and laser tubes which are considered consumables. These parts, when used, become worn, or the usable life is decreased. Laser tubes are parts that, when used, shorten its life, and especially when proper methods are not used (i.e. running the tube with water), can drastically reduce the life of the tube. Therefore, the warranty for laser tubes are 30 days if the laser tube was not used.
