Duet Maestro leds flash

[JonasBaleine]

Hi all,

I have a Duet 2 Maestro v1.0 board and a 24V power supply.

I believe (it happend quite fast) I may have shorted the fan pins on the board.
I was lazy and I disconnected a fan from its extension wires while the duet was still turned on.
Then, all the leds on the board started flashing, every second or so, so I turned off the power supply.

Now, when I turn on the power supply again, the leds flash in the same way.
I do not know how to proceed from here and would like your help in order to keep the problem from getting any worse, if there is a solution of course.

Thanks.

sounds like something is shorted and the power supply is triggering its short circuit / overload protection?

anyways, disconnect stuff to see if the fault is external to the board and follow https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond to see if you can get the board to work.
