this is for the fans, what is connected to the fan outputs?

not necessarily a problem.

see https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond for troubleshooting. no need to fix the 1a fuse to diagnose the rest really

to fan output i have connect only Pwm out put for noctua fans and water pump and small solenoid valve.
nothing more.

@matej1006 Two possibilities:

If this is an SD card that came with a new Duet 3, that message is correct and can be ignored. Those cards are formatted for use in a Raspberry Pi, and contain partitions that Windows does not understand; it therefore offers to format them.

If that card is NOT from the packaging of a new Duet3, and/or has never been in a Raspberry Pi, then there could be a problem.

the fan outputs should have diodes if its a newer board; which revision is it? inductive load does seem like the more likely culprit if nothing else changed.

i'd follow the guide i posted and use the usb cable to see if the board works, then restore the sd card if needed.

The SD card will not affect the 1A fuse, so there is probably more to it.

Which board revision is do you have?
