Question #: 875

Question: 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?

Current Solution

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 purchased limit switches from you mounted them on my machine and wire them to the breakout for using pin 12 and the ground on the breakout board, after a few minutes I got a message about a limit switch trip. Am I supposed to use the extra outport on the board instead of the ground?

    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.

  • 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.

  • I have a YDH-18-5 Power Supply AC Input:100-240v 47-63Hz, Ouput: 5v - 2A and need to know if its safe to use with the Parallel Breakout Board.

    The 5V power required for the breakout board can be a simple USB male to male cable, that will connect from your computer to the board itself.
    Now adding a external power supply make sure that it does not exceed a total of 5V and the standard 500 MilliAMP - 1 A.

  • 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.

  • 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.

  • I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

    Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

  • Hello. I'm currently building my first CNC router, and I'm powering it with a 3 axis electronics kit that was purchased through your site. I chose to get the Mach 3 USB Breakout board, but now I'm wanting to try to use Linux CNC to work with the computer I have available. Will that work with this board?
  • received my mach 3 USB breakout board today. The layout of the board is different from your diagram which shows a 5V power slot for each axis. Do I wire the 5V slot with only one 5V wire from one of the drivers or perhaps wire all three 5V wires into the one 5 V slot. Please advise.

    The board layout is different and the terminals have slightly different names, but the two boards function the same. The wiring diagram is the same for both boards. The plug-in driver for Mach3 is also the same, so you should not have a problem. If you do run into an issue, please let me know here and I will help you determine the problem.

    Thanks

    Additional Information:
    Thank you for the assurance that the boards will function the same. You did not answer the primary question of wiring. The diagram shows a board with a 5V for each axis, the new boards have only 1 5V point on the axis side. In retrospect since this controller receives information and most possibly the 5V signal directly from the computer leading to the drivers. I will wire the X, Y and Z axis to the single 5V point and see what happens.

  • if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors.

    I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

    The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

  • I have an issue about the breakout board , i can't understand why i get ( -5V) instead of ( +5V) when i measure the voltage between the "Dir" pin and " com" pin

    It sounds like the meter red and black wires are being switched around. The breakout board should not be giving you a -5 volts. The voltages should be in the range of 0 and 5 volts. The voltages will change when you move the axis in one direction or the other.

  • can I control the speed of a 2.2 spindle through your 5 axis breakout board with relay?

    Yes, you can control the speed of the 2.2 kW spindle, and the other spindles we sell, through Mach3 software. It requires making some changes to the settings in Mach3 and in your inverter. It also requires an additional part, which is called a USB to Serial Converter, found on our site here:

  • I'm looking to upgrade my X-Carve with one of your vfd spindles, can you reccomend which one to use to replace the dewalt 611 router?

    If you would like to replace a router that outputs a relatively low HP (horse power) such as the Bosch PR20EVSK or Dewalt 611, both having about 1-1.25 HP, the 1.5kW spindle would have more than enough power and will also provide constant torque where the routers are unable to achieve. The 1.5kW spindle outputs 2 HP and is water cooled to keep the dust out of the air!

  • 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.
