Question #: 14606

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

Current Solution

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.

Other Possible Solutions to this Question

  • 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).

  • how to connect USB controller to the drivers. Any instructions/video other then html datasheet?
  • I have a "Based on planet-cnc's diy cnc usb controller", how I can connect a signal to turn on a mist?

    If you need to control mist, coolant or spindle using the USB Planet-cnc controller, you will need to connect that specific output terminal to an SSR (Solid State Relay). The solid state relay will act as a switch when the output signal is engaged.

  • hey, where can i see the steps how can i control 3 or 4 step motor? can i use the Axis Electronics Combo? or i need to connect controller?

    Controlling a 3-axis or 4-axis motor configuration, you will need the following items drivers/motors/controller. Our electronics combo comes with the items mentioned and with power supply/miscellaneous items.
    The only other item needed will be a computer (with controller software) to communicate and view controls of your motors.
    Using the Parallel breakout board will use Mach 3 software, and USB will use Planet-CNC software.

  • Can I add a relay to the Mach3 USB controller?

    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:

  • I have a planetcnc USB controller to run my project and when I start the 240v router the USB connection shuts down.

    The USB controller will only work with the Planet-CNC software. This software is well made and will provide great functionality. The planet-cnc software delivers instructions to the microcontroller on the board and the microcontroller will send out the pulse trains needed to move the machine correctly.

    There are two main alternatives if you want to use the mach3 software:
    First, get a parallel port card and add it to your computer and get a parallel breakout board. If you have a laptop/notebook computer, this will not be possible.
    Second, if you have a laptop, or really want to use the USB as the main interface for controlling the machine, you will need to get the smoothstepper board which works with mach3. The price combination is much higher than the USB controller with planet-cnc, but will work with Mach3.

    Additional Information:
    The planet cnc controller can be prone to electrical interference and has been known to cause such problems. In the first instance try to use a quality double sheilded USB cable, hopefully this will fix your problem. Alternatively you may need to sheild your limit switch, estop and or motor cabling. My pick is that a quality USB cable will fix it though, worked for me.

  • How should I connect the limit switches to my laser controller?

    If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

    For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

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

  • 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.

  • 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...

  • 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.

  • I recently purchased 3 axis electronics with the USB controller board. I'm trying to install an E-stop switch. Where do I connect that on the controller board?

    There are many ways to wire an emergency stop switch. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. http://www.buildyourtools.com/phpBB3/viewtopic.php?f=12&t=4872

    Alternatively, you could use an input pin on your USB board. The wiring would depend on whether and how you might be using limit switches (single or multiple switches; normally open or normally closed). Our website datasheet for the USB board is at https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ and shows how to configure the switches for each set up. If you use this method, you'd essentially wire the e-stop as a limit switch.
