Question #: 15178

Question: [Mach3 USB Interface Board] Will this work with Mach4. I,m thinking to upgrade from Mach3.

Current Solution

The Mach3 USB will not work with Mach4. Consider the Pokeys57CNC controller instead. The Pokeys57CNC controller will work with Mach3 or Mach4 and contains more features than most CNC machines need, including 8 motor outputs, 4 onboard relays, limit home and probe inputs, galvanically isolated outputs, and much more.

  • [575] How do I get the USB Driver to work with Mach3 Version 1.84

    What problems are you experiencing?

    Additional Information:
    Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

  • [575] Does this board support indexing on mach3 turn? Planning to use it on a lathe and will do threading jobs

    You have the ability to designate the 4th axis, commonly known as the A-axis, for rotary indexing operations when using a Mach3 USB controller.

    To achieve this in Mach3, you'll need to:

    Open the Mach3 software.
    Navigate to "Config" and then to "Ports and Pins."
    Go to the "Motor Outputs" tab.
    Enable the A-axis and assign the respective Step and Direction pins.
    Save your settings and exit the "Ports and Pins" dialog.
    To calibrate the A-axis, go to "Settings" and use the "Set Steps Per Unit" option.

  • [575] I have a 64 bit Windows 11 laptop. Will this interface board work with this? If not is there an option you can suggest.

    Yes, the Mach3 USB controller will work with the latest Windows version and in 64-bit mode. The 32-bit mode is only relevant for using the parallel port driver if you are using a parallel port breakout board. Since this controller is connected via a USB cable, the 64-bit state will work fine.

  • WILL THE USB BREAKOUT BOARD WORK WITH MACH3?

    Sure, the USB interface has a place for 4 axes of limit switches.

    Each axis can have two limit switches: one for the ++ (positive) end and one for the -- (negative) end. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. The negative end would be the limit switch behind the 0 foot location behind the origin. If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). The software configurations for the limits switches are under File -> Settings -> Limit.

    A typical limit switch has three connections on it. These connections consist of COM (common), NC (normally closed) and NO (normally open). The COM would generally go to GND and the NC or the NO would go to the pin. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). Use the settings in software to set whether in NC or NO configuration.

    Let me know if this information was helpful (or not) by adding information to this question. Thanks.

    User response:
    Thank you very much for this helpful information. I'm still a little fuzzy on how the 6 limit switches physically connect to each other and to the USB breakout board. You've stated one switch (home) goes to positive and another switch (limit) goes to negative. Are all the GND prongs from all 6 switches connected to each other and going to GND on the breakout board, or no? And the NC prongs, how exactly are they connected to each other? And to the board? There has to be a diagram somewhere shows this visually, no? I don't know how to wire the switches in series or in parallel. I have already physically installed all the switches on the machine and ran the wires to where the board is. Now I just need to know where to plug these wires into the board. Also, taking into consideration that I'm using the Planet CNC software, the only settings I have pertaining to limit switches is "Enable/Disable" for each axis, and the actual limit for each axis. Nothing about NC or NO. Is that only in Mach3?
    Thank you.

    buildyourcnc response:
    On the USB interface, the COM on the switch connects to GND and the NC or NO connects to the input pin (i.e. x++, y--, etc.)

    Limit switch configuration is rather difficult to understand, especially with series and parallel. You can think of series as a single wire going from GND to the axis letter input terminal (i.e. X++ or X--). If the wire is broken, then the circuit is open (or the switch is engaged in a normally closed scenario). Normally closed is like an actual wire, and when engaged, the switch "opens" (breaks the wire). This is why we recommend in some systems that you can put many switches in series on a single pin. When one of the switches is engaged (breaking the connection) then the entire circuit of switches is broken and the machine stops.

    In a parallel scenario, the state of the circuit is always broken until the one of the switches is engaged and the circuit is then closed or connected. The topology looks like a ladder. All the switches connect to both sides of the ladder and the switches are like the runs of the ladder (the horizontal bars that the feet are placed while climbing). Imagine all of the switches broken in this scenario (normally open). It would be like the ladder could be split in two, but if one of the ladder runs (switches) is closed by engaging it, then that run would connect both sides of the ladder and the two sides of the ladder would have a connection.

    There is a diagram on the USB page of the various limit switch configurations. If you need more information (visual and/or otherwise), please let us know and we will immediately add that information to benefit everyone.

  • [575] Will the Mach3 USB interface board support other software such as Easel?

    The Mach3 USB controller is specifically engineered to integrate seamlessly with Mach3's CNC control software. Easel, on the other hand, offers an all-in-one CAD/CAM solution along with machine control capabilities. While Easel can output standard G-code compatible with industry-standard post-processors, it can serve as a design tool when used in conjunction with Mach3 but not as the machine control software.

  • [575] Hi, Can I use this board with a closed loop stepper?

    Yes, this CNC controller can be used with closed-loop stepper drivers and motors. The loop for control and feedback is between the driver and the motor. The closed-loop driver receives step and direction signals, which this controller will output which furnishes the driver with the necessary signals to move the motor. Additionally, the closed-loop driver can output a fault signal to this controller through the controller's input terminals in case the motor should encounter a situation that prevents the motor from moving so the CNC can shut down.

  • [575] Will this board operate a laser cutter and engraver

    You can adapt the Mach3 USB controller to control a laser, but I would not recommend it. A traditional laser controller that is designed to control a laser is far better since you can take advantage of more sophisticated features like sweep for engraving, and automatic adjustment of laser intensity for acceleration and deceleration. The Mach3 USB controller can move the axes and turn the laser on and off, but intensity control and engraving are not an option.

  • [575] I have one of these but pc says device is faulty. If i buy one from you will you be able to fix such problems

    If your PC is unable to communicate successfully with the Mach3 USB controller that you purchased, the problem can exist outside of the controller. If the problem is with the controller, then my controller will work. If the problem is not with the controller, then the problem will persist.

  • [575] I connected this to 24v power supply and only out3 will show 24v when activated the other 3 read 300+v whether activated or not

    Make sure that the spindle motor output pin is not interfering with the signal. Go to config -> ports and pins -> motor outputs, at the bottom of the table, there will be a line for spindle. Make sure that spindle line item is disabled.

    Additional Information:
    I disabled the spindle port and I am still only able to activate port 3 and get 24v and even there when I enter m5 the voltage bounces all over the place. The other outputs read all over the place whether they have been designated as the spindle on the spindle settings tab

  • [575] I cannot get the limits to work I’m normally open as you state

    Open the input signals dialog box by clicking on config, then ports and pins, then input signals. For each line item that you use (i.e. x++, y--, etc) make sure the port number is 3.

    Also, make sure there is a 24v power supply connected to the DCM and 24V terminals. One side of the NO on the limit switch must connect to the DCM, or the power supply V- terminal.

  • [575] Does the USB MACH3 controller support Sherline 1/2 pulse mode?

    The Mach3 100 kHz controller may be able to support the Sherline 1/2 pulse mode, but I have not tried it. There is no information in the documentation that is related to the parameter that can be set in Mach3 for the Sherline 1/2 pulse mode. You may be able to play with the available kHz ranges that the plugin allows to see if there is a pulse width that meets the Sherline 1/2 pulse mode specification.

  • [575] my axises X,Y,Z will all light green along with my soft limit switch button. When hitting REF ALL HOME no axis move and all my DROs go back to ZERO

    You need to set up the homing/limits parameters. You can find this screen by clicking config->Homing/Limits. Make sure to wire the home switches on separate input terminals (i.e. X home switch on IN1, Y home switch on IN2, etc). You can add the limit switches to any of the IN terminals, even on the same IN terminals where the home switches are located.
