Parker and Stephen discuss some MacroFab updates including news about their pod community and Slack, what’s wrong and right about high-end GPUs and the marvels of KrisFix and his YouTube repair channel, what’s up with consumer electronics and their lack of reverse polarity protection, and Parker muses about when it’s time to call it day for a 3D Printer.
