  2. Hi Dave, I am Drew Fustini from OSH Park. Sorry for the problem you experienced in
    this video. We’d like to figure out the issue since others might
    encounter it too.

    Could you please email the files so that our support
    engineers can determine how to resolve the issue?

    My email is: drew AT

    We believe there were two unrelated issues that you experienced:

    The outline on the left side was shifted down, making us unable to
    properly render the Top and Bottom previews correctly. Making the
    mechanical layer watertight will fix that.

    – The Drill files were
    being incorrectly interpreted as Metric 3:4, instead of Metric 4:3 as
    submitted. This should have been auto-corrected, but seems there’s a
    bug. For now, try just using Inch 2:4 for the drill export. The gerbers
    can stay metric as it won’t cause any problems.

    The unsupported
    slots warning is for the barrel jack, since we don’t support the Altium
    Drill Path properly. Currently, it just gets lost in our processing.
    We’re working on fixing this, but for now several slot types are
    unsupported, and require some clunky workarounds to get fabricated. You
    can see those here:

    Internal Cutouts and Slots

    And, for reference, here’s some of our documentation relevant to Altium:

  3. Spot on with this write-up, I truly feel this amazing site needs far more attention. I’ll probably be returning to see more, thanks for the advice.
