    Default My servomotor controller for hobby CNC machines

    Hi,

    I have developed a brushed servomotor controller.
    Maybe somebody is interested in it.

    The inputs are step/direction signals.(you can use MACH2-3, KCAM4, etc.)
    Maximum voltage: 90V
    Maximum current: 20A
    Selectable 2X and 4X quadrate encoder logic.
    The main controller algorithm is a modified PID alg.
    It has a PID controller manual and autotuning feature, full diagnostic via USB port and some other good features...

    The price of the controller is hobby rated
    If you are interested or have questions, write mail to: dubblecnc(at)gmail.com

    Here's the picture of my controller:

    The PCB only:

    Hi All!

    Thanks for the replys and for the e-mails.
    The price of 1 controller is 99USD.
    The shipping cost is not included in the price!

    We made an LPT port breakout board for our controller, you can connect maxium 4 servo controllers to it and all other LPT inputs and outputs can be accessed via it.
    The price of the breakout board is 39USD.
    Our website is only hungarian language, yet, but translation to english is in progress.

    You can download the datasheet of the controller from here:
    http://dubble.extra.hu/hun/whale/seroconfig.zip
    There's an english documentation in the ZIP package( /DOC_ENG). You can tune the controller with our servoconfigurator program, which is in the package, also .

    Hi!

    I uploaded another video file. It shows how easy is to tune our servo controller. No potenciometer tuning!
    Just click the start button and the PID controller is tuned in seconds.

    Download the video here:

    hello dubble:
    thats a nice looking layout you have.
    the price is very good.
    the software looks good as well.
    this is not a home normal brew controller.
    but it seems to be almost plug and play.
    have seen the ghalil self tunning software?
    o yeh, thanks for your advice on the pic forum,
    smarbaga, garry

    Hi Garry,

    Thanks for your appritiation.
    Yes, I saw the Ghalil tuning software, but I think their controller are not hobby rated, the price is a "bit" higher.

    Yes, it's easy to wire up the controllers and I think the RJ45 connectors are really good, because they're shielded and immune to industrial noise.
    The first controller was tuneable via RS232, but COM ports are limited on a computer, so we changed it to USB(virtual serial port).

    The package is natur aluminium, the bottom is 5mm wide, so it functions as a cooling rib.

    Oh, I remember you from the Microchip forum, but now I have limited time to visit the forum Maybe I will take a look today.

    HI,

    Yes we have been part of the Union since 2004. As we know you don't have to pay additional tax if you purchase from another EU member country. Of course it depends on what is your location.

    Our location is Pecs, Southwest Hungary.

    What will shipping be to US? Also what happens to the motor if the encoder signal is lost?

    Thanks

    Dennis

    I do not properly understand what have you asked about shipping.

    If you purchase a controller we send it to you in the aluminium pack as one of the above picture shows.
    The related programs and documentations you can download here for free:

    http://dubble.extra.hu/hun/whale/seroconfig.zip

    There's an english documentation in the ZIP package( /DOC_ENG). You can find the controller description and the servoconfigurator program in the package, also .

    If you need, we can send an LPT port breakout board as well:


    This board gets step/dir signals from the computer and distributes them between the controllers. Maximum 4 servo controllers can be attached to it with standard patch cables. The two connectors on the left are the unused inputs and outputs of the LPT port which can be also accessed.
    Moreover, this board can distribute digital supply, reset signal and stop signal too.
    If you connect the encoder to the controller properly, the controller will not make any failure!
    But if you don't, you can solve this problem with limitswitches.
