Question #: 14598

Question: Mach3 USB CNC Interface EMERGENCY STOP

Current Solution

To connect an emergency stop (e-stop) to the Mach3 USB controller, use the emergency stop switch/button on the NO (normally open) connections of the switch. Connect one side of the NO connection to IN1 and the other side of the NO connection to the DCM, or GND (V-) of the 24V power supply that is used to power the Mach3 USB controller.

Additional Information:
The configuration in Mach3 should be default if you used the XML file that is here:

  • Can I power the Mach3 USB interface 24V with a 48V power supply?

    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.

  • Why does Windows 10 block the RnRmotion.dill for Mach3 USB interface from being downloaded?

    Yes, Mach3 (the software profram) will work with Windows 7, and windows 10 when coupled with the Mach3 USB interface. If you intend to use the parallel port driver, stick with Windows 7 in 32-bit mode.

    Additional Information:
    Rnrmotion.dll is a dynamic link library which is very similar in function to an executable program, or app. Since a dll is executable, malicious code can be embedded in that type of file, so windows will automatically flag all files of this type. You just need to make sure you are downloading from a trusted source. The emotion.dll file on our site is clean, but still run run windows defender against it to make sure.

  • Will Mach3 USB Interface board fit in my redleaf, in lieu of the breakout board that came with it?

    The Mach3 USB board will fit in the redLeaf, but you may need to modify the Plexiglas top for proper mounting. However, the redLeaf has the proper parallel GPIO on the motherboard for use with the Parallel breakout board. If you have a laser on the machine you are using, then I would urge you to maintain the parallel breakout board as the Mach3 USB board will not work correctly using the Z-direction pin and you will need to determine how to use the output pins onthe USB board to ensure proper laser functionality.

  • Mach3 USB interface board. Could you please give me the correct wiring configuration for tool prob?

    Depending on the probe that you have, you should have two wires coming from the probe. One of those two wires will need to be connect to an input pin as shown in this wiring diagram (the diagram show the probe connected to pin I4):
    https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf

    The other pin is connected to V-. Please make sure that you have 24V connected to the V- and V+ on that side of the Mach3 USB board.

    The way the probe works is when the probe is in contact with an object, a specific spring mechanism will cause the input pin to be connected to the V- (close the circuit). When Mach3 senses an active low on the input pin, mach3 knows that the probe has made contact (closed the circuit).

    If your probe is used as a Z-Axis zero plate, then the concept is the same, but the end mill is connected to V- and the plate is connected to the input pin. If the plate comes in contact to the end mill, then the circuit is closed and mach3 will sense an active low on the input pin.

  • Mach3 USB Interface Board, Backlash Compensation in Mach3 is not working. Does this board support the backlash function?

    In our experience, the backlash compensation is not an ideal mechanism to solve backlash issues. It is best to resolve the backlash issue mechanically regather than through software.

    Boards that handle all instructions on its own chip (which is the case for this all other USB boards) take some control away from Mach3. Without Mach3 having granular control. With that said, we do not have experience with the backlash compensation with that particular board. Our experience with backlash compensation with other boards have resulted in very poor accuracy and undesirable geometrical moves.

  • I AM INTERESTED IN THE 3 AXIS COMBO USB OPTION. NOTICE YOU ENDORSE PLANET-CNC FOR USE WITH THIS BUT WILL MACH3 INTERFACE WELL BEAK OUT BOARD?
  • How do I connect a Z-Axis touch plate to the Planet-CNC USB interface?

    "Semi automatic" measuring is possible.
    1. Place movable tool sensor (touch plate) on material.
    2. Click "Measure Offset Z". Tool will move down, touch sensor and move up.
    3. "Measure Offset Z" button is still down.
    4. Click "Offset - Current Z" - this will set offset Z
    5. Click "Measure Offset Z" again to release it and restore normal mode."

    The connections to the USB interface is as follows:
    - The spindle is connected to the gnd terminal (which is also connected to the end mill). Alternatively, you can connect the gnd directly to the end mill is access is permitted.
    - The touch plate (movable tool sensor) is connected to the Z-- terminal.

    What will happen: When the end mill (gnd) is in contact with the touch plate (Z--), there will be a connection from gnd to the Z-- triggering this Z-- action and the software will recognize the connection (like a button press, or a limit switch triggering).

  • The motherboard on the computer I bought from you went out. What would you suggest. I have a laptop, could I use it and use a Mach3 USB interface board?

    Yes, you can use a laptop if you have a controller that uses a USB, like the Mach3 USB card. If you don't have that, you can purchase that part here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    If you have a controller board that connects to a 25 pin connector, modern laptops will not be able to connect to that port.

    How old is your CNC computer system?

    Additional Information:
    The CNC computer system is 2013 (5 years). The built in video card went out. I will order the Mach3 USB card. Thank you.
