Fan Failure Detection Board by Tim Abraham MMU A gantry-mounted CAN stepper driverFan Failure Detection Board This board is able to detect a stalled fan and set an output to trigger external actions. Overview This board uses the MAX6684 IC and some support parts to detect the current flowing through the fan and sets outputs based on disruptions in that current flow. By varying the value of capacitor C3 the system can be tuned for different fans. "Because of the complexity of fan current waveforms, the value of CF has to be arrived
