Like All Robots, It Must Be Supervised

I often refer to this CNC mill as a robot.  Like all robots, it is best supervised.  There's no danger of going on a rampage and terrifying the neighboring cell towers.  But the Sherline doesn't have quite enough power sometimes to rip a piece of aluminum loose, but enough power to eventually shred the power transmission belt.  These are slow and unpleasant to replace, so it is best to sit next to Millie while she is cutting metal.
