    Websrvr, I understand. It is such a disappointment that others haven't put in enough time and effort to design the schematic, write the CPLD code, produce the PCB layout for a ready to to manufacture 10ustep drive. How inconsiderate of all these people!

    Mariss from Gecko drive put the schematic and cpld code into the public domain so that those who want to learn about CPLDs, and how to use them in stepper drives, could do so.

    If you want a 10ustep stepper drive either;



    But please don't put peoples efforts down just because what they are achieving does not suit you. They are not doing it for you! they are doing it for themselves.

    When I started the thread, my motivation was to share knowledge and to encourage others to proceed. The CPLD code worked well enough for a basic driver. I don't think there is a compelling need for improvements. My only complaint is that it produces a slight hiss when idling. That is probably caused by the lack of a ground plane.

    This is not a project with widespread interest. That is why there is little interest to turn it into a production ready project or a small scale commercial product. The $10 tb6600 works well enough for most home users. Business users can easily justify buying the higher cost drivers.

    I didn't go beyond building one prototype because I moved to a DSP based design to experiment with resonance damping and closed loop control. It was mainly for fun because the tb6600 worked well enough on my sx3 mill.

    i was try with H500 verilog code with emp240, it work well

    EPM240 evelution board i was use

    Working from a dev-board is a good starting place as you can move pins around easier than remaking a PCB.

    Do you have a working driver with good results or just getting the code working on the dev-board?

    this is a quick drawring EMP240
    i believe it works well with the H bridge in previous topic
