M106 P1 C"hotend" S0 H1:2 T60Try changing the S0 to S1. When the temp is reached, you want it to turn on (S1), not off (S0).

@phaedrux Thanks, but that doesn't solve the issue of fan speed. its still much slower than a direct connection to the power supply.
-
I wonder if it's the mosfet on the Duex. The other fan headers on the duex work fine?
-
@phaedrux It's the strangest thing, but all of them do this. It's a consistent behavior.

@mentaluproar can you show your full config.g?

What position is the voltage select jumper in? Vin, 12v, or 5v?
Does disconnecting the LEDs make a difference?
Does changing the PWM frequency make a difference?
-
@phaedrux It's at 12v....because the LEDs are 12v, but the rest of the system is 24v! Of course!
I'll try fixing this tomorrow but I seem to remember there was some reason I had it wired up this way.
EDIT: I remember, I blew some of the mosfets on the duet over the years so the duet fan headers don't work right, hence I used the deus. I really should fix this things properly someday
