    While trying to fit a stupidly large aluminum heat sink on my driver chips, my board stopped cold. It didn’t die or reset, but all the motors stopped moving. Near as I can tell, I must have hit one of the SPI pins with the heat sink.

    I did some quick research of SPI, and couldn’t explain it. Does anybody have an idea?

    While my board was not harmed, did I do something bad? Or is this an acceptable way to trigger an emergency stop? Is this better or worse than using the reset button for an e-stop, like I do now?

    Thanks,

    Tom

    In the message above, I should have said ICSP, not SPI. ICSP is In-Circuit Serial Programming. Sorry.

    When you plug in your programmer it issues a reset. Simple enough. Its not dangerous just don’t do it while doing something or you will lose 🙂

    TO BE CLEAR:
    !!!!!
    !!!!!
    !!WE DO NOT HAVE AN EMERGENCY STOP!!

    Pretty dramatic but its true. A E stop is only implemented via a physical power disconnect (speaking on behalf of Synthetos). We provide some software stop’s / resets but its not an E stop. I just want to make that point clear so you don’t cut off your fingers because of a bug I might introduce in the future 🙂
