If you have a pump that has a grey and black wire on the large connector, the grey is the 12VDC V+ wire and the black wire goes to the V-. The extra wire does not need to be connected.

What we intend our customers to use for wiring the motors to the drivers will be 4 conductor 20 AWG cable, now for the PSU to Drivers; 16-18 Gauge wire should be used, and drivers to BB(Breakout Board) should be a 24 AWG wires.

In my 4'x8' Blackfoot rig, there is a maximum wire length of 16" between drivers, breakout board, and power supply as well as a maximum wire length of 10' from drivers to motors. What AWG wires should I use to connect power supply to drivers, drivers to motors, and drivers to breakout board?

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.

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.

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.

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

There is a th or tl on the laser power supply that serves as the trigger on a high or low signal. There is also a potentiometer "in" terminal that will accept a variable signal from 0v to 5v to control intensity. You can use either of these features to fire the laser tube.

If you have gotten grbl to work, then, no doubtedly, you have the expertise to know the output features of grbl. If grbl allows a pwm output, you can tie this to the potentiometer terminal on the power supply. Otherwise, you will need to use a digital output to control the power supply using th or tl.

How to wire the Laser Power Supply with an arduino & GRBL ? (I'm not using a blacktooth laser cutter)

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.

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

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 ELECTRICAL CABLE DO I USE TO CONNECT VFD INVERTER SPINDLE?

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...

The 2.5 amp driver can only accept a power supply between 12 volts and 24 volts. If a 36 volt power supply is used for this driver, the main driver chip will exceed its maximum voltage rating and cause failure.

If you need to spin your motor faster, you can either use a more appropriate driver (i.e. 3.0 amp driver) or you can change the mechanical parts so the axis has faster travel.

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:

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
