    0_1557831070297_2019_05_14 Fuses 1 out.jpg

    Now i have access to DWC, and can move the printer, bed and nozzle heats, Zprobe works.... but.... dont works fans....

    i have 4 fans:

    -1 Case fan, DONT WORKS

    • 1 Heatskin, when reach the trigger temp, DON'T WORKS
    • 2 layers fans, in these some strange, 1 semms work, but the other no.... Who i know 1 works, when power on duet, these fan spin a few....

    Ideas?
    i have changed 2 of 3 fuses of bed... 3 fuse, seems to be ok, and its only for bed. No?

    The 15A fuse (normally blue) is only for the bed. The 1A fuse (green) is for the fans, and the 7.5A fuse (brown) is for the hot end heaters and stepper motors. So if the 7.5A fuse blew, I suggest you check your hot end heater wiring very carefully.

    Does a fan connected to one of the always-on fan connectors run?



  • Hi,

    i have checked the Duet fan sockets.... and good news, they work..... all 5.

    How have checked:

    1- I have mount a Dupont conector in a spare fan.
    2- Power off Duet, and disconect from shockets all fans.
    3- First try this spare fan in alwais on shockets, firts in one, power off and after in second.... all 2 works.
    4- After, i have used similar procedure for layer/gcode fans, only when i power on Duet, i shich on/off fans with DWC.

    Conclusion:

    All fans shockets works... next step, try fans....



  • Mmmm....

    something is not right ....

    After changing the fuse, for a 2A ... the printer has worked properly ... but it has lasted little .. After two or three restart ... The case fan, it has stopped working again, a spare one that had mounted.

    The novelty ... the Duet board works ... the only thing that has stopped working has been the fan of the box, This time o can access to DWC.

    The theory that I have , is that the 2A fuse is very big, and not proyect enough, but the case has down.

    The question would be.

    If the problem is caused by what protects that fuse ...

    What do they protector the fuses?
    What should I look to find the problem?
    The heating cartridge?


  • administrators

    Are you saying that the 2A fuse has blown too?



  • No.... Its Ok... But case fan dont works now... And when i have changed (the fan)... Worked
