  • 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.

  • 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.

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

    We have a USB interface (breakout board) that will eliminate the need for a parallel cable. The USB requires the planet-cnc software to control the board.

  • I have a parallel. breakout board. and no parallel port at the back of my computer do those parallel. cards. work 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.

  • 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)

  • 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.

  • can i use a usb to parallel port adapter to connect breakout board to computer? (using mach 3)

    Unfortunately no. The parallel port allows for digital signals to be output from 17 pins simultaneously (in parallel). Parallel port adapters tries to achieve this by receiving instructions in a two wire (USB) data signal and convert that to 17 disparate signals. This type of data transmission is too slow for the drivers of a CNC machine or router.

  • is there a pci express parallel card that supports mach 3 with windows 7

    Any parallel PCI-E card should work with mach 3 and windows 7, but you will need to know the port that the card will be using (example: 0x378).

    In mach 3 go to Config/Ports&Pins/PortsSetup&AxisSelection

    Additional Information:
    Once the PCI adapter is installed. Check the device manager on that lpt port and look at the I/O range. You will need to use the first I/O address in the range for the port address entry in Mach3.

  • Should I connect both the USB and the 25 pin connector of the parallel breakout board to the computer?

    The parallel breakout board has the db25 connector for data and the USB connector for power. Connect the USB from the computer to the parallel breakout board so the breakout board will have 5V of power coming from the computer. The db25 connector (connector with the 25 pins) receive data signals for each pin from 1 to 17 and have respective numbered screw terminals, some for input and some for output (18 to 25 are gnd pins).
