BTT SKR Mini E3 v3.0 -- Part Cooling Fan (FAN0) Issues

[OGAwesomer]

Hello!

I finally have time to deal with this issue after trying to resolve it back in June. . .

I cannot get the FAN0 to operate the part cooling fan. The fan works fine when plugged into FAN1 (hotend fan), but nothing coming from FAN0. I checked with a multimeter -- there is a ~0V when the fan is set to 0%, and ~24.27V when the fan is set to 100%. But the fan does not operate. What's the deal here? Anyone else have this issue? It is only an issue on my BTT SKR Mini E3 v3.0 board.

Thanks!

I cannot reproduce the issue here.

Which fan option did you set in Prusa_AIO_Configuration.h and which fan are you using?

Hey Keith,

So, it turns out that 5 of my 6 fans purchased were bad. I got it figured out and things are working right now. Thanks for the response and all you do!

Bummer, but glad you got it figured out.
