The 3D printer controller

in 3D Model, DIY by DP | 6 comments


Matthew of Electronics for Humans has been working on 3D printer controller:

The design is based on an Atmel Atmega328 running at 8MHz (using the internal clock) at 3.3V. This is in order to keep the same voltage as the main controller board, which will be powered by the LPC1768 that only works at 3.3V or thereabouts. Furthermore, I am intending to use the Arduino Bootloader (at least at first) and the Arduino platform in general to program it. The reasons for this choice will be explained later.

    Writing “Copyright xxx” on a board and placing it next to the OSHW logo seems kind of contradictory, doesn’t it?

    • James says:

      Not at all, open hardware doesn’t mean public domain any more than open source software does.

      The creator of something still possesses the copyright unless they expressly transfer it to somebody else.

      The creator simply chooses to licence that hardware design to others, for free, given the conditions of the licence.

    • Thiago F Macedo says:

      Not exactly, does it? He can have the sources open and closed maintenance.

  2. Tim says:

    Why? He still has the copyright doesn’t he?

  3. Matthew says:

    Indeed I do :P It means I keep ownership, but I’m releasing the source for the perhaps benefit of others.

  4. The controller looks neat in concept. I’d like to see it in actual, working form! And it’s always better to be safe than sorry with the copyright issues!
