Fan output



  • I am trying to use a fan [fan1] output to drive a relay input.
    However, even if I use a M106 P1 S0 command, the voltage drops only to 0.4 volts, which is not low enough to switch the relay off. Any thoughts on how to pull the fan output closer to 0V?



  • you can add a transistor to solve this look at this example
