Am I wiring something wrong?



  • I have an E3D Titan aero and I have my hotend fan plugged into fan 1 that should be thermostatically controlled with the hot end heating to 45oC but the thing will not turn on?

    [[G-Code]]
    M106 P0 S0 I0 F500 H-1 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
    M106 P1 S1 I0 F500 H T45 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
    
    

    I've tested the fan connecting it directly to the 12v power supply and it is perfectly fine any suggestions?



  • M106 P1 S1 I0 F500 H T45

    The H value should be the heater you want to use for the thermostatic control, such as [c]H1[/c].



  • It looks to me like you haven't associated a heater with the fan. Your M106 should have "H1" not simply "H".

    Edit. Typing at the same time as the above poster.



  • Thank you! Turns out it was a combination of two things! Added the H1 and it was a dodgy crimp on the connector!
