The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

Additional Information:
Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

I have your Mach3 usb interface board and am interested in the relay board to turn plasma torch on/off. I have a different relay board that doesn't work, it needs 0/5v from output pin to trigger and the usb board doesn't put out 5 volts. Does this relay board need 5v on output or will work fine with this usb controller?

Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am installing a mach 3 usb controller into a wright cnc plasma table and I need instruction on wiring the thc (proma compact ) torch height controller to this board. IE will this board work to replace the parallel port board with usb controller board?

Yes, you can absolutely communicate with the Pokeys57CNC controller. The developer's website has various ways of control, including their poblock software, or directly programming using C#, or C++. I have tested the C# method for a job I did for Lockheed Martin and worked really well.

Hi i am interested in the greenBull 6x with Hybrid Laser/Spindle Head (includes Spindle/VFD and Laser Components) - USB Interface (Long Z). I was wondering how much it would cost to get this machine to NZ?

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.

Good evening, if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors. I have a 48V 12amp power supply. Thank you

Yes, the Mach3 USB board has two terminals that require 24V connection. Most VFDs have a 24V output that can be used to power this part of the Mach3 USB board.

The V+ and V- on the Mach3 USB is not absolutely necessary to operate the CNC machine/router. The V+ and V- of the Mach3 USB board powers the outputs, inputs, and spindle's speed and control.

Here is the Mach3 USB link for more information:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

The new YL600 VFD we have in stock may not have this 24V output. There is a 12V terminal, but I have not tested that terminal if it outputs 12V, or if it is a 12V input. If you are only conecting limit switches to the Mach3 USB and need to power that portion, 12V will be sufficient.

I will delve into these aspects in far more detail on video.

Thanks and Merry Christmas to you as well!

Hey Guys, I have a brand new redleaf and 5x. In the final stages of wiring and wondering a few things. Can I connect the Mach3 USB board V+ V- to my frequency inverter (type YL600-2s-2k20)? If so where? Will your upcoming (part 2)video deal with this as well as final connections for limit switches and stop button? Merry Christmas!

Yes, you can use a corner plate very easily. You will want to make a corner plate that has three independent plates that do not conduct with each other. Each of these plates will be connected to a different input (i.e. IN1 for X, IN2 for Y and IN3 for Z). The end mill or tool that is inserted into the spindle will connect to V- of the 24V power supply, or the DCM on the controller, which is connected to the 24V V-. Then, you can use the ref all home button on the program run screen of Mach3.

Is there a way to use an X,Y plate that will only be responsible for corner finding in Mach3 with the Mach3 USB controller?

We currently do not have any step down adapters for the vacuum pressure sensor, and would recommend looking at local hardware stores or major online hardware suppliers (ex: McMaster, grainger) . However it is something you will be need to be very specific with, ex: Barb 1/4" Hose ID to 1/8" Hose ID Reducer Fitting. Is something I would recommend when trying to fit a larger tube.

I am interested in using your vacuum pump controller pressure switch for one of our applications. However, I am concerned about having a proper connection from the 1/16" sensor barb to our vacuum line. Do you carry adapter of common sizes to step down to a 1/16" line? If not, do you know who might? (I have already done some prelim searching with little luck)

I bought a 'BuildyourCNC V1' relay board to go with my mach3 usb controller. I have been sent a 'Songle' relay. It's not the one in your picture and it's got different connections, for which there isn't a wiring diagram. The one I ordered says it is 5v, this one seems to be saying it's a 24v unit. Can you please explain what has happened? Thanks

I also place the controller very close to the drivers (on the back of the gantry). All of the cables are shielded. The only long cables are the mains power cables and the USB cable. The USB cable is shielded and contains active repeaters.

There is no problem putting all of the electronics in a box and using long cables to the motors. This is the way I did it for a very long time.

Great site. I saw your videos of wiring the Mach3 USB controller. You place the drivers next to the Steppers. This means that you have very long leads to the USB Board? What about the placement of the controlling PC? Is it a problem to have the USB board, PSUs and Drivers in a control box and long leads to the steppers? Thank you.

I have the mach 3 USB board running a XYZ router, and a Z touch off (button style @ fixed position). I am wondering if there's a way to also use an X,Y plate that will only be responsible for corner finding. Is the digitize input the only input that can be used for a touch plate?

The Mach3 USB interface board will require a 24V power supply to enable the use of the input, output terminals, and the spindle VFD 0-10V and output for speed control.

Hi Patrick right now I have a parallel port cnc machine that I built in 2013 using the hardware and components I purchased from your website. I want to update my system by changing my current parallel port interface board to a Mach3 USB interface board from your website. Is the Mach3 USB interface board all I need to do this or is there other components I need to get. please advise.

If the sensors are NC (normally closed) you can wire them in series. If the sensors are NO (Normally Open) you can still wire them to the same input, but the wiring needs to be in parallel (like a ladder). I have more information on the following video:

[788] Thanks for the oportunity to ask, I am building a cnc and using npn closed sensors could you help me with the conection of these, do i still connect them in series if i use more than two in each axis. Also you mention that a stop switch should be connected grd and input to the controller would that be done after the 24v power supply. Thanks r

If the outputs are not functioning as expected on the Mach3 USB controller, confirm that the port for the output is 3. This is a part of the configuration I did not show on the video I created on using the outputs for the RNRMotion controller.

Additional Information:
Thanks for your help. Under Ports & Pins>Output Signals I show Output#1 through Output#4 as Enabled. All have Port# set to 3. Pin Numbers for each Output# are same as Output# (Output#1 set to Pin Number 1, etc.).
Still no voltage showing on output 1 (of the board) when I input M3 in the Input section of the MDI tab. However if (in Spindle Setup tab) I set (in "Relay Control")M3 Output# to 3 and M4 Output# to 4 things work as expected. Is it possible to have the M3 signal show up on Output#1?
Thanks again.
