Duet 2 wifi fans not working
-
I had a print failure, filament got into the hotend fan and tore the wiring off causing a short in the 1a fuse. I replaced the fuse and i cannot get power to p1. I configured to use p2 as a work around, it powers on for a second on boot up and then I cannot get it going after that (trying temp >50c, or using m106). this is a new fan with complete new wiring and I can get this fan working on an always on fan block. Is my board destroyed or do i have any options to get it working again?

How is it configured? And what firmware?

it is running 2.05.1
Configuration:
M106 P1 S1 I0 F500 H1 T45
M106 P2 S1 I0 F500 H1 T45 -
If P1 fan port doesnt work, you should comment first line out. With second line try to change frequency, some fans dont work good at all with PWM signal. And be sure your fan is connected to Fan 2 connector, the leftmost of fan connectors and not to Fan 0 connector.
There is of course possibility, that this short fried up your fan mosfets as well. Take a close look of them and see if there are any signs of damage. -

Does your fan mosfet look like that?
