@underpk said in Can I bypass fan VIN?:

Hi, recently my fans are not working on my Duet2 wifi board. I check the continuity between VIN and VIN on the jumper selection under fans connectors and they are not connect to each other.

If your Duet is recent enough to have a fan fuse, that's unusual, because the fuse should protect the PCB traces.

I suggest you use your multimeter to trace between +VIN and the fan fuse, and between the fan fuse and the VNINpin on the fan voltage select jumper; then bypass whichever of those traces has failed.
