3.01-RC10 - Extruder cooling fan not turn on



  • Hello,
    I have IDEX printer and I use slicer Simplify3D and after upgrade firmware from 3.01-RC8 to 3.01-RC10 I have the problem with cooling fan of extruder. When I start printing extruder cooling fan do not turn on. When I cancel print extruder coling fan turn on. Manually I can turn on extruder cooling fan, when I manualy adjust extruder temperature then cooling fan works.

    This is really strange behavior and I do not know why. Do you have any ideas?

    Here is part of starting g-code from Simplify3D:

    There is a known issue in RC10 that may be causing this depending on your config.g file. Previously, a minimum 50% PWM was enforced for any thermostatic cooling fan. So if you have this in config.g:

    M106 P1 T45 H1 S0

    then in effect the S0 would be ignored and 50% PWM is used. That doesn't happen in RC10.

    Use S1 in any M106 command that declares a fan to be thermostatic, or whatever lower value you want to use.



  • Before I had this settings of fans in config.g file:

    ; Fans
    M950 F1 C"fan1"
    M106 P1 H1 T45 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
    M950 F0 C"fan0"
    M106 P0 H2 T45 ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on
    M950 F3 C"duex.fan3"
    M106 P3 H-1 C"Chlazeni levy"
    M950 F4 C"duex.fan4"
    M106 P4 H-1 C"Chlazeni pravy"
    M950 F5 C"duex.fan5"
    M106 P5 T32:40 H100:101:102 C"Duet Fan" ;cooling fan that starts to turn on when the MCU temperature (virtual heater 100) reaches 45C and reaches full speed when the MCU temperature reaches 65C or if any TMC2660 drivers (virtual heaters 101 and 102) report that they are over-temperature

    For your advice I edited config.g file. Now I have this settings of fans:

    ; Fans
    M950 F1 C"fan1"
    M106 P1 H1 T45 S1 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
    M950 F0 C"fan0"
    M106 P0 H2 T45 S1 ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on
    M950 F3 C"duex.fan3"
    M106 P3 H-1 C"Chlazeni levy"
    M950 F4 C"duex.fan4"
    M106 P4 H-1 C"Chlazeni pravy"
    M950 F5 C"duex.fan5"
    M106 P5 T32:40 H100:101:102 C"Duet Fan" ;cooling fan that starts to turn on when the MCU temperature (virtual heater 100) reaches 45C and reaches full speed when the MCU temperature reaches 65C or if any TMC2660 drivers (virtual heaters 101 and 102) report that they are over-temperature

    Unfortunately the behavior is the same. Cooling fan of extruder still not turn on after starting print.

    I tried another settings M106 P1 H1 T45 S255 and M106 P0 H2 T45 S255, but without any changes cooling fan of extruder still not turn on after starting print.

  • I check settings of tools in my config.g and I think that maybe I have mistake in parameter M563 and mapping fans for tools.

    Current:
    M563 P0 D0 H1 X3 F3 ; Define tool 0

    M563 P1 D1 H2 F4 ; Define tool 1

    New settings:
    M563 P0 D0 H1 X3 F0:3 ; Define tool 0

    M563 P1 D1 H2 F1:4 ; Define tool 1

    What do you think? Now I am at work. After I will come home I check it.


  • administrators

    You original settings look correct to me, because it is only the part cooling fan that you should declare in M563, not the heatsink cooling fan.

    Please try upgrading to 3.01-RC11 when we release it later this afternoon.



  • Thank you. After update firmware to 3.01-RC11 extruder fan turn on and works after starting print.
