Question about fan control
-
Ok Yes I figured I would just let the hotend fan run whenever the power was on so i connected to always on. It spins just fine. Just cant get the part cooling fan to work
-
Ok so for the hell of it I hooked both the hotend and part cooling fan0 and fan1. Both dont work
I've checked all three fuses and they are ok
-
Try again, but this time change your fan commands in config.g to look like this
M106 P0 S0.5 H-1 M106 P1 S0.5 H-1 M106 P2 S0.5 H-1That should turn all 3 fan ports on at 50% for testing.

That worked
-
@jtroutt19 OK they are working with temp now. Not sure what I was doing wrong. I need to take a break seems like
-
Ok, so if you plug the fans into the recommended ports and follow the fan config example I posted above you should be good to go.
Part cooling on Fan0, Hotend on Fan1
M106 P0 S0 H-1 C"Part Cooling"
M106 P1 S1 H1 T45 C"Hotend Fan" -
Yip So the firmware config tool sets them up like this
M106 P1 S1 I0 F500 H1 T45
So exactly like you showed. I removed the "I" and the "F" and they started working like they should.
Thank you very much for you help.

@phaedrux
One more thing right quick the Part cooling fan is not shutting off when temp drops below 45°c. Hotend fan does -
That's because the part cooling fan isn't thermostatically controlled. It's controlled by the slicer in the gcode, or manually with the slider in DWC.

Ok I see it now. Right on thanks again
