@dalias@hachyderm.io There indeed is technology that can do it. SawStop is a system for table saws that can sense when the operator's skin touches the blade, and stops and retracts the blade almost instantly. Not sure if they could implement it for lathes or metal presses though. https://en.wikipedia.org/wiki/SawStop @muetdhiver@piaille.fr @mothninja@beige.party
