    pminmo,

    Post them in the new links section. There is a place for Opensource Designs.
    They sound good, I will have a look at them myself.

    Thanks,
    Chris

    I see two Open source links, one for machines one for software. What about for electronics?

    Great job Phil & guys. We should have a party.

    The first open source boards developed by that funny little crowd who speak a foreign language to most here. I will ask Paul to set up a section for them to be downloaded.

    Phil, there is now a new section created for " Free/Open-source CNC electronics Schematics and artwork" you can access it from here http://cnczone.com/modules.php?name=...ategory&cid=58

    If you would prefere CNCZone to host the file, please send it to admin@cnczone.com

    Schematic and Artwork ?

    Can you double check the link you gave ? It gives me an "Invalid Article Specified error message when I follow it.

    Thanks

    I was looking for the schematic / artwork of the open source controller.

    Ynneb gave a link http://cnczone.com/modules.php?name=...ategory&cid=58
    indicating the files where local to cnczone, but that link doesn't work for me.

    Where can I find the copper layer for the 3977 boards? I saw it available for the 5804 and the 297/298 versions, but not for the chips *I* have.

    Isn't that always the way it goes? ;-)

    Talking

    Chuck I can post the copper if you like. Or email, It's a double sided board, 10mil traces and clearance, A lot of via's. Not much or a board for the DIY'er unless you have em made by a pcb house.

    Phil

    I attached though if you are so inclined.

    Are your copper images mirrored, for toner transfer? I just don't want to mess up, on my first attempt.
