Question #: 14643

Question: Can I add a relay to the Mach3 USB controller?

Current Solution

Yes, you can add a relay to the Mach3 USB controller. The relay must be a 24V relay on it's input side and be able to be set to active low. I demonstrate this in a video on the following page:

The video is titled: Mach3 USB Controller Outputs

Other Possible Solutions to this Question

  • How can I connect an inductive proximity sensor to the Mach3 USB controller?

    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.

  • How do I use the outputs on the Mach3 USB controller?

    I created a video to demonstrate how to use the outputs on the Mach3 USB controller. You can find this video on the following page:

  • How do you install the software for the Mach3 USB controller?

    The Mach3 usb controller/interface has instructions and videos on this page:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    There is a 5 step process on that page to install the plug-in and the configuration xml file that is necessary for the proper functioning of the controller.

    The videos on that page also demonstrate in detail how to install the software, plug-ins, xml file and wiring and testing most of the features of the Mach3 USB interface.

    Hope this helps.

  • Is there a kit or actual product that can be wired into the Mach3 controller to give me virtual zero

    The mach3 control software will work with all major CAM software (CAMBAM, Aspire and Vectric, BobCAD/CAM, ArtCAM, Dolphin CAM, CAM software that integrate with SolidWorks and AutoDesk Inventor, and many more).

  • Can I run two stepper motors off the same axis output on the USB controller?

    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...

  • Can I add a fourth axis by just adding another controller?

    In generally, you would only need a driver to drive the motor on the 4th axis.

    A fourth (4th) axis can be added using a head stock that contains a motor where the motor turns a chuck that holds the object. The motor requires a driver that is controlled by an interface card such as the parallel breakout board, or the usb controller board. Our 4th Axis head stock can be driven by our standard 3.0 amp driver.

    The software used to control the 4th axis would need to be able to control 4 axes (X, Y, Z and A). Mach3, LinuzCNC and Planet-CNC are good examples of control software that can control more than 3 axes.

  • where on your mk1 usb controller is the input port i can use for pause or estop comand thanks

    On our USB breakout boards, the pins available for any inputs (e-stop/limit switches).
    Are x++ - a-- (x++,x--,y,z,a(same)) in the settings menu you will have to specify the pin!

    Here is a good forum on Planet-CNC.com to help setting up Planet-CNC software:(http://www.planet-cnc.com/faq/machine_setup/)

    Additional Information:
    In the planetcnc software the inputs are greyed out I have a licenced copy and I have all limits setup and working correctly id like to use the a++ or a-- as a manual program pause if my plasma fails torch ignition and id like it to continue after re ignition. When the mk1 controller is unplugged the inputs are available but when the controller is plugged in there greyed out is these options unavailable with your controller please help.

  • Can you shortcut the usb controller that comes with the blacktooth laser to hardware reset it?

    The USB controller does not have a reset button installed on it.

    You have some alternate options however:
    - You can remove the USB connector and re-insert it.
    - Set the USB to use external 5v by removing the jumper near the USB connector, use a 5v wall adapter and install a switch along the 5v DC power line to turn it off then on. You can use a momentary push button switch to do this.

  • how to control the spindle with the usb controller

    To control a spindle using the USB CNC interface, you will need a relay board that contains a transistor that can activate the relay with a power source with enough current that can activate the relay. This video explains all of the information you will need to develop this relay circuit:

  • Is it possible to add proximity sensors with your USB Controller Board

    Yes, proximity sensors work similarly to limit switches. There are three connections that connect to the signal (input terminal) and two power connections that is connected to the 24V power supply that supplies the Mach3 USB controller. I have only tested NPN proximity switches with that controller in NO (normally open mode).

  • Hi I have a Proxxon MF70, I want to add 3axis stepper with controller and software by USB. Can you suggest a kit for me? Thanks.

    To implement a electronics combo to run you Proxxon MF70, you will need to find the correct drive components (ACME screw, linear rail, etc) and look into any specific modifications needed to your rig.
    I would recommend the USB 3 Axis Large Motors Electronics w/ USB Interface Board.
    Since the machine is metal, our larger motors would be highly recommended.

    We have not done this conversion, through research is recommended.

  • I there a tutorial on hooking up a Z axis zero touch plate to the usb controller?

    To use a touch plate on any controller, all you need is a conductive flat material with a known thickness and some wire and alligator clips. Solder a wire to the touch plate and connect the other end of the wire to the free input terminal of the controller. Connect a wire with an alligator clip to the ground of the controller (on the Mach3 USB controller, this ground is the DCM terminal, or the digital gnd on the 24VDC power supply). Connect the alligator clip to the end mill.

    You can either use a script to serve as the probe, or you can use the ref all home button and setup the touch plate as a home switch.
