Closed-loop 3D printing with Optical Encoders
Chris wrote in with a link to a great project I’ve wanted to see for years: closed-loop 3D printing.
An open loop machine run blind. anything pushes them off course and they won’t know it. In 3D printing this nearly always means restarting from scratch.
Closed loop machines are more self-aware (not in a Skynet kind of way!). They’re programed to correct themselves, meaning less failed prints.
Misan replaced the stepper motors in his 3D printer with DC motors that have optical encoders. The encoders sense how far the motors move. Misan can even force them off track mid-print and the machine will correct itself. Perfect!
