Anet A8 Fan Issue
-
Photo of your wiring?
Do the fans work if connected directly to the outputs of the buck converter? (assuming that's what you're using to get your 12v?)
-
@Veti the fan does not work always on and the fuse is good
-
@Phaedrux
The photo will not so much but here it is.
I am using an open spot from the 12V PS, which is also used for the other fans to have airflow in my electrical box.
The fans do work when they have power directly from the PS.
-
Can you draw up a wiring diagram showing how you have your 12v supply hooked up?
It looks like that white and blue wire is going to the V_fan pin, correct? Are you actually getting 12v on that wire?
-
-
Post your full config.g
Also post the results of M122 and M98 P"config.g" -
carefully measure the power on the fan pins.
be very careful, if you slip, you will break the fan port. -

Which fan is connected where?
-
@Phaedrux
Extruder fan is always onParts cooling fan is F1

M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on ;;;;;;;;;;;;;; TOOLS ;;;;;;;;;;;;;;;;;; M563 P0 D0 H1 ; define tool 0You should use Fan0 for the part cooling fan and Fan1 for the hotend heatsink if possible. That would match your config and the default fan usage.
If that's not possible, you'd need to change your fan config up.
-
@Phaedrux
Wouldn't one fan or the other turn on, with the way the config is setup now? -
Do I need to create the pin numbers using M574? I'm doubting this question, but it's a long shot for me right now.
-
I would expect the always on fan ports to work. Are you sure the fan fuse is intact? Did you check it with a multimeter?
Your part cooling fan would only turn on when the heater reaches 45c.

No.
-
The fuse was checked with multimeter, It's not blown.
I am reading 7.6V across the fan pins. With an external 5V from a buck.
I probed my V_FAN pin, verified 12V from PS.
-
And you checked the fan fuse and not the vin fuse?
What do you mean by external 5v from a buck?

I probed my V_FAN pin, verified 12V from PS.a buck converter is a step down converter. you can use 5v on a buck converter to output 12v
