I once saw a guy in the local maker space spend a couple hours programming a CNC milling machine &amp; arranging a complicate series of clamps and shims to hold a work piece he intended to drill. 15 seconds into his run the drill bit bound up in the work piece. Since the mill was set to pulse drill on the up stroke it snatched the work piece out of the jig that was holding it. On the next downstroke it totally obliterated his jig and then hurled the work piece across the machine shop. 15 feet away there was a set of collets that would have worked way better than the printed ABS widget he was using to hold his workpiece. There was also a bog standard drill press standing next to the table the collets were on. If this dude had simply chucked his piece in a collet and walked over to the drill press his parts run would have taken 15 minutes, likely with no ballistic interludes. The really shocking part was that he was in the machine shop at all. Normally it, the welding stations, and the wood shop were deserted and there was always a line (sometimes hours long) to access the laser cutter, 3d printer, and CNC router table. The three tools in the shop that could be controlled with a laptop and that required no direct tool use on the part of the operator. That always bothered me for reasons I can&#x27;t fully articulate.
