  • Using USB Controller Board with Planet-CNC software. The S/W recognizes limit switches but not soft limits. Help?

    "Soft limits are used to decelerate machine to stop before machine is stopped hard way at limit switch or before it crashes. I recommend "Soft Limits Decelerate" and "Soft Limits Strict" settings are also checked. Sometimes we need to disable soft limits and there is a command for this in menu "Machine/Soft Limits". When soft limit is triggered position display will be yellow."

    Are the soft limits "grayed out"?

  • how do I control coolant mist using the mach3usb break out board

    You will need a 24V relay controlled by one of the output terminals of the Mach3 USB controller. You can see a video that demonstrates the use of the output pins for this controller and how a relay is connected to the output terminal and the power supply. It is the video that is titled "Mach3 USB Controller Outputs"

  • 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 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.

  • What power supply do you recommend for the spindle and limit switches if I buy the USB Mach3 breakout board?

    Any of the following power supplies will be fine for powering the Mach3 USB controller:
    https://www.buildyourcnc.com/item/24v

    however, the limit switches do not need high current, so the following power supply is sufficient for the task of connecting limit switches:

  • How do I get Homing on Z to work with Plate and Ground using Buildyourcnc usb board all the entries for the sensor in planet-cnc are grayed out. I am using input z- and I purchased the software

    To home the z-axis using a plate:
    - Connect the end mill using a large clamping device like an alligator clip with a wire connected to GND.

    - Connect the plate (solder a wire to the plate) to one of the input pins.

    - You can use the autoset to setup that pin in Mach3 simply by touching the two together once connected to the pin and GND.

    Alternatively, the end mill can be connected to the pin and the plate connected to GND as long as there becomes a complete circuit when the end mill touches the plate.

    To setup homing for the Planet-CNC homing and limits, go to the Planet-CNC Machine setup page which explains the process step by step: http://www.planet-cnc.com/faq/machine_setup/

  • I have a 64 bit operating system and the Mach3 usb control board. What do i need to communicate between the two?

    You will need a USB cable to connect the computer and the Mach3 USB. The 64-bit operating system must be Windows and you will need the Mach3 CNC control software installed on the operating system.

    You will need to install the USB driver called RNRMotion.dll. You can find the driver here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    Move the file to your Mach3 Plugins folder Example: "C:/Users/ProgramFiles/Mach3/Plugins"

    Mach3 will prompt you to select a driver and this is where you can select the "RnRMotionController" and check "Don't ask me again". This will allow your board to communicate with Mach3.

    You will also need the xml file found on this page: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    On that page, you will need to download the XML Mach3 Config File by right clicking on the link and selecting "save as". Save the Mach3Mill.xml file in your Mach3 root folder.

    That file is the main configuration file for the Mach3 board. It has all of the typical settings that the Mach3 board needs.
