M106 X0.5 -> How should it work?



  • I´ve read the wiki and I though that this setup
    M106 P1 S1 I0 F500 H1 T45 X127
    or
    M106 P1 S1 I0 F500 H1 T45 X0.5

    would set my extruder fan termo regulated, but with a maximum pwm of 0.5 so if I run psu at 24v, I should be getting 12v in that output, but It doesn´t seem to be working that way.

    Could somebody share how I works with me? thanks

    PWM turns the whole 24V on and off very rapidly. A voltmeter won't show this.

    Perhaps even more importantly: PWM on Duets switches the GROUND (negative) pin on/off rapidly. The + pin will be a very steady Vin (24V)
