Hi. My Duet3 6HC rev.1.02 after start print after a few printed layers it stops communicating with RRF36, more precisely it stops extruding thread and moving Z up, with baby steps I try to move but the motors just buzz and don't move. Could there be a problem with the board? I have a spare one but it's a clone version 1.01, I'll try it.

@edsped
Hello, I found the problem, not every fan is suitable for Can.
I tried several models and found the right one, now I'm satisfied.
Thanks for the help though.

@gloomyandy
Thanks

@agz90
I tried swapping them but then none of the fans start. On the board, the diode lights up, but no fan moves.

and where to set the fans with M563

I currently have a Fly-Super8Pro H723 board I'm experimenting with and my BTT Octopus Pro v1.0 F429 running on Voron 2.4.

the heater works, the extruder cooling fan works, but the parts cooling fan does not.
