[797] What power supply should I use for this relay?

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 an Eagle Plasma table and I want to add a 40 laser. Can you supply me a list of what I need to make this happen.

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.

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

You can use the standard electronics combo: http://www.buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo. The size of the stepping motors are generally sized with the overall machine structural weight, inertia of parts, the type of mechanical parts used to move the axes, and actually, less by the router which is more connect to how the machine is controlled.

If I use a Porter Cable 3-3/4 router motor what size stepper motors do I need?

Since this 4th axis already comes with a stepper motor, you will need a driver and some cable to connect to the driver from where the 4th axis will be placed. If you have extra space in the redFly electronics enclosure, you can fasten the driver there. You will also need some wire to connect the driver to the breakout baord.

Make sure that the spindle motor output pin is not interfering with the signal. Go to config -> ports and pins -> motor outputs, at the bottom of the table, there will be a line for spindle. Make sure that spindle line item is disabled.

Additional Information:
I disabled the spindle port and I am still only able to activate port 3 and get 24v and even there when I enter m5 the voltage bounces all over the place. The other outputs read all over the place whether they have been designated as the spindle on the spindle settings tab

Here is a list of the parts needed to get the electronics combo functioning (parallel or USB interface options):

- 22 or 24 gauge stranded hookup wire to connect all of the drivers to the USB or parallel interface (terminal to terminal connections),
- 18 gauge stranded hookup wire to connect the drivers to the power supply,
- a power cable (extension cord) to connect from the power outlet to the power supply,
- 4 conductor cable to connect the drivers to the stepper motors,
- a USB cable to connect from the computer to the USB interface (or for power to the parallel interface),
- for the parallel interface, a parallel cable is needed (male to male db-25),
- a computer (for parallel interface, the computer will need a parallel port and if the computer does not contain a parallel interface, the motherboard may have a header for it, or you can purchase a parallel adapter to plug into the motherboard, very inexpensive),
- cnc control software: for the USB interface, you will need planet-cnc software, for the parallel interface, you can use any industry standard cnc control software (the typical is Mach3 for Windows, or EMC2 or Linuxcnc for Linux (Linuxcnc.org).

5v power supply is not needed. The 5 volts signal level power is derived from the computer through USB on both types of interfaces.

If you are using a spindle with a VFD, there is a 24 volt power supply that will provide the correct power for the V+ and V- on the Mach3 USB. The 12V option is only if you are using the limit switches on that side of the board, but if you are using it to control spindle speed and for the outputs, it's best to use a 24V power supply, or the 24V output on the VFD.

The mach3 USB card requires 24V, how do I supply this?

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.

The 5V power required for the breakout board can be a simple USB male to male cable, that will connect from your computer to the board itself.
Now adding a external power supply make sure that it does not exceed a total of 5V and the standard 500 MilliAMP - 1 A.

The greenBull 4X comes with all of the components and electronics to assemble the gantry of the machine. You will need to build the table. We provide the rails and roller chain for the X-axis (along the length of the table for full 8 feet of travel). You will need to provide some wire to connect the electronics and a computer to run the machine. You will also need to purchase the software that you will need to run the machine that matches how you will apply the machine. We suggest the mach3 control program. The CAM program is up to you as there are many options out there.

WHAT DOES THE GREENBULL KIT INCLUDE AND DO I NEED TO INCLUDE?

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.

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.
