Part fans no spinning on T1 and T3 on new e3d Tool Changer

[Phaedrux]

Send these in turn to test all the fans

M106 P1 S1 H-1
M106 P2 S1 H-1
M106 P3 S1 H-1
M106 P4 S1 H-1
M106 P5 S1 H-1
M106 P6 S1 H-1
M106 P7 S1 H-1
M106 P8 S1 H-1

P# addresses the fan
H-1 turns off thermostatic mode so they can be manually controlled.
S1 sets them to full power.

can you snap a close up photo of the fan headers on the duex? Sometimes there is visible damage to the fan mosfets.

Ok, so please recap for me, since it's been a long thread.

When sending the fan commands I posted above, which fans do not work?

For the fans that do not work, you have tested the fans themselves in other working ports to confirm they actually work there?

[rmilyard]

@Phaedrux P106 commands for T1 and T3 don't work. All others do.

@rmilyard said in Part fans no spinning on T1 and T3 on new e3d Tool Changer:

M950 F1 C"fan1"
M950 F3 C"duex.fan3"

So fan1 is on the Duet and Fan3 is on the Duex. Correct?

@rmilyard So none of the T1 and T3 fans work? Not even hotend fan.

[rmilyard]

@Rushmere3D so think found issue. If I get the fans anywhere near the extruder the fan stops. I have not tried to steal washers and still doesn't work.

[rmilyard]

Fans need to be away from stepper almost half inche. Anything can think other than steel washers?

[rmilyard]

I have some zinc washers but ones I have are thick. Going order some from Amazon.

[rmilyard]

Thanks all for help! It was combo that my old harness had wire issue and these 2 fans needed zinc washer. Seems like fan working now.
