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 use your USB interface board and Mach3 on my 3 axis CNC router?

    Planet-CNC is the control software. If you decide to use the USB controller, you will need to use the planet-CNC software as the control software. You will be able to use any of the CAM software applications with the planet-CNC control software.

  • Will the mach3 usb interface card work with Windows 7?

    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.

  • 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?
  • The electronics for my current cnc machine has a 36v 8.8 amp power supply. Is this power supply sufficient to power my new Mach3 USB interface?

    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.

  • 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.

  • Can I use your USB interface board and Mach4 on my 3 axis CNC router?

    The USB interface that we sell only works with planet-cnc software. We will be developing our own USB board and plug-in that will work with Mach4 very soon.

  • 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).

  • Will the Mach3 interface board accommodate 5 wire steppers?

    Wow, I've never heard of 5 wire stepper motors. Typically, stepper motors have two wires per coil (the start and end of the coil) and sometimes there is a midpoint wire on each coil making for 6 wires. Other stepper motors may have the midpoint cut and two wires extending from the midpoint (essentially making 4 coils) which creates 8 wire stepper motors.

    Having 5 wires seems odd to me. Can you measure the resistance between the 5 wires with all combinations?

  • Is there a downloadable manual for the usb Mach3 interface board? I'm not sure one came with my Redleaf. Cheers.
  • 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.

    WHICH WIRES ARE CONNECTED TO THE EMERGENCY STOP BUTTON

  • Do you have any tutorial about conecting emergency stop buttom?

    We currently do not have a tutorial on setting up the emergency e-stop button, however it works very similar to a limit switch. (limit switch tutorial: https://buildyourcnc.com/PrimeronHomingandLimitSwitches.aspx)

    There is 2 sides to the e-stop, first being green NO-Normally Open and secondly being red NC-Normally Closed. From these two sides you will have too choose in which manner you would like to wired the e-stop.
    If you plan on smashing the button when there is a problem, (as we all do :D) we would recommend wiring it in normally open - Green side. The wiring is simple, you will only need 2 wires going from GND to the input pin, the orientation of the wires is not as important with these switches.

    Setup
    Mach 3:
    You will go to config/ports&pins/inputsignals, there will be one item in that tab enable, e-stop, you will then enter the pin number and you are done.

    Planet-CNC:(with our board) there is not designated pin which we would recommend wiring it directly to the power cord going to your CNC electronic power supply. Wire it in normally open and to the live/load wire.

    3rd party board compatible with planet-cnc or a direct planet-cnc board, go to file/settings/general, there you will choose the output pin for your e-stop as stated on the board schematic.

    "On a personal note: I have ran into 1 issue once being that they placed the colored covers on the opposite sides, which means that green is red, and red is green. I only ran into this once but I would rather share this info. as a possiblity."
