  • How do you wire the connection between the vfd and the pokoys57cnc breakout board?

    The Pokeys57cnc board: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

    This board contains a 0-10V output at pin #17 that can be connected to the spindle's VFD 0-10V input. On the VFD, this terminal is typically called AI0 or above.

    Pin #14 on the Pokeys57cnc board can also be used as a spindle error input.

    The Galvanically isolated I/O section of terminals on the Pokeys57cnc board (which also contain the pins 14 and 18, can be used to serve as the on/off for the spindle/VFD using the VFDs digital input.

  • 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).

  • How to connect the 5 axis breakout board(old one) to the 1 Watt laser driver TTL input?

    Depending on the model BoB, we recommend wiring it to pin 6 or CP- for your z axis since our blackTooth laser and laser/spindle hybrid, will use the Z-axis as a trigger to enable the laser just as a CNC will use pin 6 or CP- for the z-axis to enable going downwards into the material.



    Additional Information:

    This is the BoB that i have.
    I am an absolute beginner at this laser stuff. So if i wire it to pin 6 which is the z axis step pin on my board. what else needs to be done if i am using the mach3 engraving plugin. Can i use the step pin of the 4th and 5th axis instead?

  • For your USB breakout board, do you guys have, or have a source for a connector that fits over the "keyboard jog" pins?

    At the current moment, we do not have a connector/attachment for the keyboard jog pins on our USB Breakout board. We are currently under development of a keyboard jog panel, that will connect to the keyboard jog pins.

  • HOW DO I WIRE FROM THE BREAKOUT BOARD TO DRIVER?

    CP+ to COM
    CP- to STEP
    CP+ to CW+ (small jumper wire)
    CW- to DIR

    Additional Information:
    If the driver does not have CP or CW labels, the CP is Step and the CW is Direction or DIR. If you connect the 5v to CP+ (or Step+) and CW+ (or DIR+) and the pin to CP- (or Step-) and another pin to CW- (or DIR-), then in software, the configuration for the step on that axis must be active low. Otherwise, if you connect the GND to CP- (or Step-) and CW- (or DIR-) and the pin to CP+ (or Step+) and another pin to CW+ (or DIR+), then in software, the configuration for the step on that axis must be active high.

    Additional Information:
    If you have a driver that is labeled pul, dir and ena: Pul+ is the Step+ and Pul- is the Step-. Pul is short for pulse. A pulse will create a step. Don't worry about the enable terminals.

    On the x-axis, pin #2 can go to pul- and pin #3 can go to dir-. The 5v will go to pul+ and dir+. The configuration for each axis for step will be active low and toggle active low for the dir on each axis to make it go in the direction desired.

  • 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).

  • I connected 5Vdc power to the alternet connector of the USB Breakoutboard with the proper jumper setting and the board fried. What did I do wrong?

    Can you test the output of the 5V DC adapter to check the output voltage?

    Additional Information:
    The 5VDC voltage was generated by a PC ATX power supply and was measured (5.0VDC) just before connecting it to the controller PCB. I also verified polarity prior to powering up.

    Additional Information:
    Please call us to initiate a replacement of the USB interface. We would also like the existing USB interface to be return so that we can investigate the cause of this failure.

  • Breakout Board with Relay. What is the USB connection on this board for? Does this board Still require a 5v power supply?

    We generally use the USB to power the interface (breakout board). The current from the computer is sufficient to supply the breakout board.

  • Installing THC to my limit ports on the breakout board. Once wired how do I get Mach 3 to reconize the port?

    Getting continuity from the x--/x++ might not mean it is a faulty board, unless they are bridged, so both get a pulse rather than one. But to check if you might have a opposite connection for those input:
    Planet-cnc/file/settings/input/invert inputs/input 1/input 2.

    Additional Information:
    In input port section in config. Scroll down and you will see THC On, Up and Down. Enter your input pin numbers there.

  • I need wiring instructions for the breakout board you sent yesterday. It is not like the one in the videos and I don't know where to connect the 5V. No data sheet or anything.
  • 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.

  • 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.

  • The breakout board that I have says that on the input pins I have five volts, the plan calls for these pins are ground connectors, which. Is correct?

    If you have the breakout board from this site, then the input pins have gnd connectors next to them. If you have a breakout board purchased elsewhere, or one of our older breakout boards, you may need to use the 5V connectors as the return, but make sure that the jumpers are set correctly. If you don't get any action from these switches in your software, recheck the jumpers and connections, or use the GND terminals on the power supply.
