Question #: 3408

Question: Does your breakout board work with low voltage 3.3volt parallel ports?

Current Solution

The breakout board will work with 3.3 volt parallel port. The integrated circuits on the board bring the level up to 5 volts for each pin when engaged. The breakout board is powered from the USB port and this is where the 5 volts is acquired.

  • MY COMPUTER DOES NOT HAVE A PARALLEL PORT. HOW DO I INTERFACE WITH THE BREAKOUT BOARD?

    If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

  • I have your breakout board with relay parallel port , how can I wire up a regular router to that board so I can control the router

    Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit.

    See this image of a similar connection. The terminal has the same connections.
    https://www.buildyourcnc.com/images/vacuum-pressure-controller-relay-terminals-700.JPG

    Image of the relay terminal:
    https://www.buildyourcnc.com/images/breakoutboardrelayNONC.PNG

    The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router.


    Additional Information:
    You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

    Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.

  • My computer doesn't have a parallel port connection. Can I use a usb to parallel port cable to communicate with my breakout board?

    A parallel to USB adapter will not work. You will need to use a USB interface like the ones below:

    Mach3 USB interface:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    Poeys57CNC Interface:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

    Additional Information:
    To answer the question in more detail, the parallel port is actually an extension straight from the CPU and is also called the GPIO (General Purpose I/O) pins. These pins carry signals independently, hence the description as being a parallel port.

    The stepper motor driver receives a pulse train (series of pulses). A single pin on the parallel port sends a pulse train to one stepper motor driver and stepper motor for a single axis. Another pin on the parallel port sends a pulse train to another stepper motor driver on another axis. This happens simultaneously as with the direction signals for each axis.

    If a parallel port is adapted through a USB (using an adapter), the parallel port cannot have these signals happen in a simultaneous fashion and will cause the stepper motors of a CNC router or machine to be very clunky, if it works at all. To elaborate, the computer sends an instruction to the USB to send a high signal to pin 1, so it does, then another signal to pin 2, so it does. This is happening one after another. The speed at which this happens is reduced dramatically, and the position of one axis may now be out of sync to another axis.

    The reason the USB interfaces (linked above) work is that the USB delivers broad instructions to the interface (to a microcontroller) and the interface parses the instructions and outputs simultaneous signals to the stepper motor drivers.

    Hope this helps.

  • can I use the usb on the parallel breakout board with planet cmc

    The USB on the Parallel breakout board, is used for powering the board itself (5v USB), and the Parallel to communicate directly between the drivers and the computer/mach 3.
    Planet-CNC cannot be used with our Parallel Breakout Board, it is only intend to be used with Mach 3/other open source programs.

    To use Planet-CNC, please refer to our USB breakout board! (https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout)

  • why does the parallel port breakout board have usb port?

    The parallel breakout board contains a USB port to power the board. Through the USB port, the computer delivers 5v of stable power to the parallel breakout board, but doe not provide any communication as would normally be associated with USB connectivity.

    The reason we elected to use the USB port to provide power is to remove the need for an external 5v wall adapter.

  • will your parallel port breakout board fry my motherboard in any unfortunate event?

    The parallel breakout board can damage the motherboard if anything happens to the board to cause a error. The parallel BoB, is tested before shipment so it should not cause any damage on arrival.
    As most electronic components there are a lot of possibilities that may cause damaged. If your motherboard is having issues or you are concerned about the parallel breakout board causing damaged.
    We recommend to try to run your computer with both the parallel and USB power disconnected from your computer and run a project without the CNC connected and test for irregularities with the computer running.
    Then add the cables for the breakout board and re-test.

  • Planet-CNC breakout board supports encoder inputs. I don't see this feature on your's. How does your board support threding, etc.?

    We need clarification on what you mean by threading: a parallel computer process, creating threads on a screw on a turning center, or threading a hole using a tap controlled by a CNC machine. If it's the latter two, you would rely on the stepping motors and dead reckoning (open loop system). Stepping motors will move exactly as instructed and have exact stop and positional accuracy so the threads would be constructed as intended; therefore, no need for encoders and feedback (closed loop system)

    What he is asking perhaps is that how would he be able to do rigid tapping without encoder input? Alternatively, he may need a servo drive for the spindle. Which board supports rotary encoder input? I am looking for boards myself.

  • i want to use servo motors(panasonic liqi series) instead of stepper motor,would it work with your breakout board if i buy one from you?

    I would need to see the drivers and what type of input it requires.

    Additional Information:
    actually my neighbour is using panasonic liqi series servo motors, and yes i can show you the connections he made on the driver terminals. he had used a loacal made breakout board, which i dont want to use... the breakout board has 5 terminals, step,direction,vcc,ground,and 12v

    Additional Information:
    The connections are the same as stepping motor drivers. I would assume that those servo motors have the closed loop control between the motor and driver and the computer is not considered as a part of the closed loop. In that case, the breakout board would work fine.

    Additional Information:
    i've seen your videos related to the connections of the breakout board to the motor driver,your breakout board dont have 12v terminal as in that local made breakout board.can i provide that extra 12v from another source to the servo motor driver?
    i can send you the photos of the driver connections and the breakout board connections?
    how can i purchase your breakout board,can you send your parallel port breakout board to my country?
    how much would it cost me including shipping?

    Additional Information:
    What terminals will require the 12v power. If the 12v serves as the data signal level power for step and direction, then it is not possible with this board, but if the 12v serves as power for another part of the driver, then you can use a separate supply.

  • I would like to know if your breakout board and driver boards are compatible with MAC OS X working with Sketch Up pro using SketchUcam ?

    SketchUcam will output gcode which standard CNC control software will typically interpret, execute and control CNC machines. So, there is no problem using SketchUcam. However, our CNC machine control software that use our CNC machine interface boards require Windows OS, of Linux. The Mach3 USB board will only run with Mach3 control software which runs under the Windows OS. The parallel breakout board can run under Windows or Linux OS and the computer must contain a parallel port.

  • WHATISTHE DIFFERENCE WTIH THE PARALLEL BREAKOUT BOARD AND USB BOARD?

    The parallel is the most versatile breakout board we have and will work with most of the software out there, but many computers are not equipped with parallel connectors anymore. Parallel adapter cards are available if you don't have a parallel connection on your computer.

    The USB interface must be used only with the planet-cnc software, which is great software, but you are still limited to only that software application. This is actually the least expensive option unless you use linux and go with the above option.

  • WHAT'S THE DIFFERENCE BETWEEN PARALLEL BREAKOUT BOARD AND USB ITERFACE?

    The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

    The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

    The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

  • Will the Mach 3 USB breakout board work with a Windows 7 64 bit system?

    I don't see why Mach3 under windows 64-bit wouldn't work with an interface that uses USB as it's primary communication method. I am a bit vague on this, so I will do more research on it.

    We recommend Mach3 run under Windows 32-bit when using the parallel interface as this is a legacy function.
