Fans not spinning
-
I have 2 out of 3 fans not spinning on my printer, they're connected to 'fan1' and 'fan0', the 3rd is connected to 'fan2' and works fine. I've tested the fans to verify they work, however the pins don't seem to work. I'm using a duet 2 maestro from M3D, here is my config file

What voltage are the fans?
Have you configured the jumpers?Refer to the notes here
Duet 2 Maestro has two 3-pin jumpers (V_FAN_A and V_FAN_B) to select fan pin voltages between VIN or the Duet's 5V supply. V FAN A controls FAN0, FAN1 and the always-on fan pins, V_FAN_B controls FAN2. You can supply a different voltage to the centre pin of the 3-pin jumper, pin V_FAN_A or V_FAN_B, to run fans at different voltages.

@owend
I changed the jumper placement and they work! I didn't know they were important before you mentioned them, thanks! -
