Question #: 1175

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

Current Solution

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.

  • I purchased the 4.0kw spindle and VFD a while back, and have just installed a PMDX-107 controller... do you have any examples of the wiring connections for the SL-240EE to PMDX-107?

    If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

    If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

    PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
    PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
    PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
    PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
    PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

    Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.

  • I trying to setup your USB Controller card. The planetcnc does not load the card, no driver for usb card. Using windows 8.1.

    To install the USB breakout board, there will be no driver to install nor any pop-up will be viewed in your windows task-bar, except only to notify that a USB device has been connected.

    If you have planet-cnc installed it should automatically ask for a license number, which if you don't have you will continue without entering any numbers. Please read carefully since there is a pop-up that can erase the entire firmware on your board, and you will basically have a dead board.

    Please email customerservice@buildyourcnc.com for further assitance.

    Additional Information:
    For Windows 8.1 you need to follow special driver installation steps. Download Planet-cnc software MANUAL and scroll down to that paragraph (without it you will not be able to install and use your board).

  • Must I have licence to run planetpc software, is there any other software that will run the usb controller

    The Planet CNC Software will require purchase after the trial version is completed, and will be purchased through their website. Currently that is the only software available for the USB Controller.

  • I have registered version of planetcnc software that I purchased with a Chinese controller I want to use 3 better drivers with a separate USB controller can you recommend a controller and how to link my existing software. Regards Lloyd from Australia

    You can only use the planet-cnc interfaces with the PlanetCNC software. If you like the software and want to remain with that software, the hardware interfaces will need to be purchased from the planet-cnc folks.

    I would recommend using the Pokeys57CNC interface which is compatible with Mach3 and Mach4. You can also consider the Mach3 USB interface if the Pokeys57CNc interface is out of your price range.

  • I have a "Based on planet-cnc's diy cnc usb controller", I activated the output signal (mist, coolant or spindle) in the planetcnc software but at the output there is no voltage, what can I do to turn on this elements?

    On the Planet-CNC board, the Mist, Spindle and Coolant outputs will require a relay to switch on those devices. Test one of those terminals with a multi-meter (Mist, Coolant, or Spindle). Each of these terminals have a GND next to the terminal for the device.

    Test the voltage across the GND to the terminal with the arrow that you want to test. Go to the software and click on the device you want to test (mist, coolant or spindle) and note the voltage. If no voltage is output then check under the board to where the terminals are soldered. Re-test the terminals across the solder joints rather than the terminal block wire inputs. If you get a voltage, then there is a problem with the terminal block. If you don't get a voltage, then the board is not functioning properly.

    Additional Information:
    I activated the output signal.. I did the tests indicated and I did not get voltage. I heated the welds of the three outputs and now works coolant but no mist or spindle, what should I do?

    Additional Information:
    There are probably cold joints on the board at the chip or the resistors on the traces for those terminals. You can send the board back to us and we will repair and test the board.

    Additional Information:
    If you want to troubleshoot this yourself, take a very close look at the traces from the terminal and follow them to the tiny resistors, then to the legs of the chip. If you see any bad or bridged solder joints, then those will need to be re-touched. It will take a somewhat experienced soldering individual to accomplish this task and will require flux to make sure the solder joints are fully joined.

  • I have a breakout board and it appears that the pin 12 connection has failed: when i move my limit switches to pin 11 they work; they don't work on pin 12. Do i need a new breakout board?

    For safety's sake I would recommend a new board because they are inexpensive compared to the electronics that they support. Alternatively, it's possible that the one dead pin is a simple fix, such as a bad connection or solder joint; if you feel comfortable making those repairs then it could be worthwhile to check. Finally, if you are not using all the input pins, you could continue to operate the limit switch on pin 11 and hope for the best.

  • Please advise correct wiring from PLANETCNC USB controller Mk3/4 to motor driver.
  • the breakout board that i recieved has both a 25pin and usb connections. can i use the usb to plug into my laptop

    A parallel breakout board requires a computer with a parallel port. The parallel port provides the communication. The reason the board has a USB port is only to provide power to the board from the computer. If the USB connection is not plugged in to the board, the board will not have the power needed to function correctly.

  • I bought a 'BuildyourCNC V1' relay board to go with my mach3 usb controller. I have been sent a 'Songle' relay. It's not the one in your picture and it's got different connections, for which there isn't a wiring diagram. The one I ordered says it is 5v, this one seems to be saying it's a 24v unit. Can you please explain what has happened? Thanks

    The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

    Additional Information:
    I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

    Additional Information:
    Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

  • When I start my spindle I get a emergency stop in Mach 3. I have run shielded cable and it is grounded at the VFD it is wired per you site instructions. any idea what to check

    You will definitely want to adjust your debounce setting in mach3 if your emergency or limit switch is engaging.

  • I have the usb breakout board https://buildyourcnc.com/Item/electronicsAndMotors-electronic-component-USB-Controller-Breakout and need to run the A axis as a slave the software greys out the box how do I fix this?

    You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
    The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.
    The items you will need for a water cooled spindle would be: water pump, silicon tubing(length desired by customer), a extension cord(from a hardware store(orange))(1 same gauge wire/length as extension cord).

  • I have not used my CNC router (Mach3, USB interface board) for several months. When I tried to use it, all 3 stepper motors moved extremely slowly. Where should I start troubleshooting?

    If your motors turn very slowly using your Mach3 USB board, then either the pulse from the board is being output at a slow rate or the motor drivers are set to a higher than expected microstepping:

    The Mach3 USB board outputs the pulse rather than the computer, but Mach3 controls this pulse frequency within the motor tuning section. First, determine if the travel distance is correct with the computer and the physical travel of the machine.

    If the travel is different, then your stepper motor driver's microstepping is incorrect, or the steps per inch/mm in the motor tuning within Mach3 is incorrect.

    If the travel is correct, then simply change the velocity and acceleration parameters to your desired level. If Mach3 will not achieve the velocity you desire, then decrease your stepper motor driver's microstepping setting, readjust the step per inch/mm in mach3 and readjust the acceleration and velocity to your desired levels.

  • i have cnc router. when I do text I have to flip it upsidedown (in software) else it prints backwards. Bottom left is zero and x and y go plus from there. y has dir low checked x does not.

    Is bottom left your zero with regard to screen position, or actual machine position (looking down at the machine)? You will want the zero of the machine to reflect that of the screen. This is to make the safest possible scenario for working with the machine and it insures that the output will match that of the screen.

    User response:
    I'll answer my own question. Unchecked Dir Low on "Y" text now cuts the way you see it in Mach 3. The only thing now is "Y" is plus moving from right to left. I don't think that makes much difference as long as I know that. I'm not sure what will happen if I used a file from someone else. Any opinions?

    buildyourcnc response:
    It is still recommended that the origin is located where you would expect it to be on the machine. It sounds like the origin is at the right. It also helps to orient the keyboard when jogging where the machine movement matches the direction of the arrow keys.

  • Hi I have a Proxxon MF70, I want to add 3axis stepper with controller and software by USB. Can you suggest a kit for me? Thanks.

    To implement a electronics combo to run you Proxxon MF70, you will need to find the correct drive components (ACME screw, linear rail, etc) and look into any specific modifications needed to your rig.
    I would recommend the USB 3 Axis Large Motors Electronics w/ USB Interface Board.
    Since the machine is metal, our larger motors would be highly recommended.

    We have not done this conversion, through research is recommended.
